Ive been waiting a while for someone to bring forward something about the cause in detail, its good to finally see what is going on in there. Cheers guys

[@knobblyknob]

And people always seem so surprised when they get the bill for not servicing their transmissions.........There's a lot going on in there. Top work gentlemen.

[@jasongrant6939]

Holden has the first auto service scheduled at 140,000km, mine started shuddering at 84,000km. Mostly highway use for work, no offroad use and lucky to have towed a small tinny a hand full of times. Many people in the same boat as me if you start looking on colorado pages

[@jacksonwelch9870]

@@jasongrant6939the service interval for the autos has been “revised” by Holden to the 72,000km or 75,000km interval depending on what schedule your car is on

[@kepamurray1845]

Mine started at 43k and I had the transmission fluid flushed but the gearbox was out before it hit 60k. Jason is right about the servicing interval. "Fill for life transmission" was the service department managers comment. No warranty either.

[@stealth5959]

I just love watching your work on automatic transmissions. First, find the issue and upgrade the new parts. A real professional team at work.

[@WholesaleAutomatics]

Thanks for the kind words!

[@jamesgeorge4874]

TCC shudder is becoming common on everything, because the fluid is thinner, and more slippery than before, and the friction modifier blend oxidizes out faster, because these units are all clutch to clutch shifted and the regulation valves are moving continuously in their respective bores.

[@lukekerr7528]

That's the most attention I have ever payed to any video. I have one of the formerly mentioned vehicles that's had 2 torque converters and is causing chaos again. Rocket Rod, we'll certainly be in touch

[@craigmurphy1852]

That's interesting. I was a mechanic working for Holden. They were stating it was a torque convertor fault. We where only instructed to fit new ones. I wonder if they new the route cause and didn't acknowledge due to costs???

[@rosewood1]

I have a 2014 Colorado LTZ 4wd. Lots of very heavy towing since brand new. No problems 180K trans serviced by dealer 3 times so far. After 2014 a different transmission was fitted to Colorados and this clearly has been less reliable for many. Great that you are able to fix the problem properly. These are excellent reliable vehicles that are very capable. Money on the transmission is very well spent especially when you look at the cost of a new vehicle these days.

[@mitchell8934]

Transmissions were ok on the early models. Wasn’t until the updated model that they had the common shudder problem.

[@joshuagibson1825]

I think they started having that issue after 2017 woth the facelift and updated torque converter

[@horsehead8306]

My 2015 model has trans issues now after 250,000kms. It’s been serviced 4 times now. It’s t pitty wholesale automatics it’s over 1800km away. I wouldn’t trust the local auto shop to fix it properly 🤦‍♂️

Wish you guys were here in the U.S I'd be on the way to see guys. You obviously know what you are talking about. I have a 17 Colorado with a 2.8 liter diesel in it. Love the truck minus the transmission. I've had the same issues when towing with it. The shudder and at one point a millisecond lock up in tow haul mode going up hill. As soon as the transmission gets warm from towing it all starts. Shifts really smooth if your not towing and just normal driving but when you start working the transmission it all comes back. Took it to the dealer and had the thing flushed out and a TCM update but it all came back. Initially it started just driving it around while not towing anything. Thought it was all cured until I started towing with it after that. Like I said it all came back and worse. Anyway great video. Wish I knew of someone here in the states I could take it to with your knowledge.

[@trevorharper5151]

The over pressure from the worn valve will normally blow out the discs on the pressure switches to the TECHM too.

[@ashleydruce9777]

I own a rg and know absolutely nothing about "the shudder". I've got 250k on mine,runs sweeeet. Fitted a cooler from new and change fluid every 4th -8th oil change.Only oem fluid,happy days.Great box

[@WholesaleAutomatics]

This is a very common statement from the Colorado owners. Oil cooler seems to make a difference.

[@ashleydruce9777]

@@WholesaleAutomatics Yea Just a shame Holden were such tight asses.Like Australia doesnt warrant it,with 3.5tonne capacity etc etc etc

[@craighoffman6876]

Great video, it all makes sense. GM saved a few pennies here, and now we have to deal with it, usually out of warranty. Likely exacerbating the shudder issue - soft/slippy transmission programming and of course the lack of an external transmission cooler. It is stupid that the 2.8 diesel has an integrated in the radiator cooler while the V6 gets a big boy pants external cooler. They got it backwards, as usual 😆 I have a '17 Canyon with the 2.8, GDE engine and transmission tuned it at 10K miles and changed the OEM fill at 40K miles in favor of full synthetic. So far so fine, it sure shifts firmer and better after tuning the transmission's calibrations. I wager the tune + the hardware updates covered in the video would be awesome together. Wish you were in America as it is hard to find this kind of in depth knowledge here. As a nation I think we have gotten substantially dumber over the last 20 years or so in general, and too many repair shops and especially dealers are populated by code readers and parts swappers. Few holistically understand how systems work anymore...

Excelent video on what can go wrong and what needs to be fixed.

[@craigbright7400]

Interesting video. Holden have gone back to the "triple flush" of the trans fluid. Good to see someone actually finding the root cause

[@jayryia]

Interesting: I have a relative with one in Trinidad and the company stated it was a torque converter issue. Changed and over time, it did the same. He had it to a specialist who changes dome valve body components, among other things I can't recall. But what I was wondering is, many of the US users in forums stated the issue came down to the dexron6 ATF the company uses and by using a specific one (Mobil 1 HLVP) it stopped the shudder. I can't explain it.

[@WholesaleAutomatics]

The dealer are trying the oil change here as well, unfortunately they are having hit and miss success depending on the condition of the lock-up please in the torque convertor and the valve set.

[@jorjimaco5331]

I’ve had your twin oil cooler setup for over 80k and not 1 drama. On my second oil change and tow a 3 ton van around. Nothing over 85 ever. Cheers

[@Approach_Medium]

Wow, uh thanks for answering what nobody in the USA could about this trans for the past 6 years i have had my truck. Its been doing this since the day i took it home from the dealer new. They just kept telling me it was the tires but it would not go away. Its always worse in the warm months. I hope i can locate the updated parts in the states and get mine fixed correctly

Holden dealers are carrying out a triple flush before replacing any parts. Most of the time that seems to work.

[@ianmilne7047]

I have the vehicle you described and the shudder issue, have had it back to the dealer/stealer and each time no fault found and for me is getting worse. It's still in warranty till the end of the year but they choose to do nothing, the truck itself is great for what I do just need to sort the shudder out😢. Great job fella's what sort of $ to have this sorted, might be worth the road trip

[@ripperripper4076]

Hi Rod, something I would like to understand is why were are not seeing the same consistent issue across all gearboxes. I definitely acknowledge there is a fundamental issue with the valves as I am part of a number of groups where people are having issues anywhere from 20k up to 100k and beyond. I have a 2017 trailblazer, so just after the pre-facelift when the issue started to rear its head. I wouldnt say its had an easy life. I have towed caravans on the very limit, have done what I would consider somewhat serious 4wding enough to push the car to its limits with lockers as well as a lot of beach driving. I have had the TB tuned, bigger tyres and higher lift basically everything you would expect to considerably put more stress on the transmission. The car has 182k on it and have had a few issues but never a transmission shudder, which I am very surprised. I have done 2 transmission services on it and installed one of your coolers at around 90k. Given the history of the car I thought it would have been a prime candidate for the shudder. I have considered it is maybe shear luck, but I am stumped as to why it hasnt developed the shudder, other than possible inconsistent QA/QC of the valve hardness given the wear you are seeing in other gearboxes. Do you have any thoughts on why this issue is seen in basically soccer mum cars with low kms versus high km hard driven cars?

[@WholesaleAutomatics]

This a great question and I believe, and this is only my personal opinion but changing the oil from what was originally used and adding a cooler would make a difference. We know that Holden is changing the oil to be different from what was originally used but I don't know in what way. The early models didn't seem to have the problem and for the most part the torque convertor is the victim and not the cause. It can be the valve as seen and we will certainly see a lot more of these as the years go on. It's also pressure management and we know that the only sure way is to do a valve upgrade set, billet torque convertor and we HIGHLY recommend the oil cooler and aftermarket full synthetic oil. There are many that have no problem, in fact most don't, you mostly only hear about those who are. We have not done a case study to what the common factors are to those who do and those who don't, but we all know that we will see more as the years go on.

Hey Rod.. I work FIFO I can leave my 2018 Colorado Auto sit for 3 weeks some times.. I idle the car for a good 5 minutes before I drive off for the first time.. but when I put it in Drive and start to roll forward it can take a good second to build up drive and finally start moving.. it's fine after a week.. maybe 2. very much more prevalent after 3.... 140k on the clock has always seem to happen.. only ever noticed this in the Colorado

[@WholesaleAutomatics]

Can be the same pressure reg valve that we mentioned in this episode bleeding oil back from the torque convertor into the pan. Letting the car run for a few second recharges the torque convertor and you are good to go. Unfortunately no quick fix but no harm being done either until the shudder starts then you will to rebuild and upgrade.

[@christophermarshall5765]

I’m glad my cars don’t have one of these transmissions in them. My old Mercedes Benz 450SE has a 3 speed automatic transmission that has 2 pumps in it. This is designed so the car can be roll started down hill, or tow started. My A180 has a dct type transmission. I recently serviced the V8 transmission, and the dealer serviced the dct in my A180, as the A180 has warranty on it. I’m not keen on the transmissions built by GM. One would think they would have built them better. When I saw that valve, I knew it was worn out. Makes me glad I am retired.

[@andrewford80]

Love these videos. It's so good to get to see the innards! My Triton has a factory ATF cooler, but I'm always very conscious of ATF temps and monitor them when driving via obd2. What is the general opinion on what constitutes "too high"? Mine measures at two locations, the carter and the oil pipe. I've only seen it reach 104c before, max. That was 2nd gear up a really steep hill with the camper trailer on the back. Generally it's 80-90c. Cheers for the content. Keep it up!

[@WholesaleAutomatics]

120c is to hot. 104 is ok.

[@denzomurrayo2827]

At the very least they should replace the TC -absolutely no chance they can deny that. If you can push it then either a transmission replacement or decent service (I failed to get either). I’ll be asking my mechanic to upgrade the transmission at next service. Good luck.

[@jaredwhitby6279]

Hey Rocket, nice in depth video on what the actual problem is as Holden are just doing these so called triple flushes to cover the issue until your out of warranty and they kick you out afterwards. I have a question mine has 111,000km but never experienced the shudder but flairing would this be the issue for that as well?

I haven’t got a shudder, however, when I take my foot off the accelerator I can heard a low pitched whining noise that gets louder as the vehicle slows. Does this sound like a transmission issue?

[@philmarriott8084]

Good job as always Rocket! Just curious.. if the valve body is worn then wouldn’t the opposing surfaces inside the housing also be worn? It just seemed to me that only half the problem is being solved by changing all the valves.. but I’m not a gearbox specialist just a mechanically minded guy..

[@WholesaleAutomatics]

That is very true in many circumstances and we would ream the bore and oversize the valve to suit, this is very common with the Ford Ranger 6 speed autos and a few odd valves across other makes and models. However the valve bore in the Colorado seems to remain largely unaffected and the vacuum test was perfect with the new valve.

[@neilmay3420]

[@soloryderrr]

Rod, do you know if Holden/GM has updated these valves on more recent 6L50 transmissions? I had the shudder as well on my 2019 ZR2 diesel colorado and GM is replacing the whole transmission with a new unit

[@WholesaleAutomatics]

No, the valves that we use in our heavy duty Colorado builds are custom made to suit. They are not genuine.

[@tonymontana897]

My 2020 Colorado has that same shudder sometimes and I definitely feel the torque converter slippage between the lower gears as you push on off the mark, I usually back the accelerator off a bit to not put too much pressure on it so it can shift up better, but yes, it is a P.O.S of a transmission. Your upgrade sounds expensive though, but what choice do we have when the manufacturer dumps a bad design on us. I don't think my car has any more warranty either. Even if it did, what would they do anyway ?? Replace the torque converter or that valve for a short term fix until the car well and truly runs out of warranty, then they can tell you to go get stuffed after. What a disgrace. No wonder Holden went out of business.

[@justjoe8303]

Interesting that another automatic specialist in SEQLD believes the issue is the valve body and provide an upgrade kit.

[@WholesaleAutomatics]

The valve body only has a few valves, all the major valves are in the pump assembly. You watched the video and saw what we found.

[@Danos011]

Great video as per usual. Ive just had this happen to my colorado and holdens current warranty fix is to tripple flush the fluid. Are you able to explain how this could possibly fix a mechanical problem like any of the ones you mentioned in the video?

[@WholesaleAutomatics]

It certainly can't if the damage is already done and I have no way of knowing if they are adding any sort of additive to the oil to reduce shudder. I can't comment on exactly what they are doing or even what the hell a triple flush is. We do full flush transmission services but as a transmission specialist a triple flush doesn't sound like a correct terminology for what they might be trying to achieve.

[@Danos011]

To me changing the oil three times(and running it in between) means they really want to get all the oil out of all the nooks and crannys. But that just tells us they think the problem is the oil. The oil can only be contaminated by worn or failed parts or cooked from overheating in my mind. It's definitely made the shudder disappear for now. But just feels like a temporary solution to a more serious problem.

[@index6738]

Holden say its the torque converter which fails though Holden attempt to flush transmission hoping all clutch particles from burnt TC clutch hasn’t caused fowling down steam. However, flushing waste time since problem originated from TCC valve. Holden known for replacing both TC and transmission. Don’t be fooled by flushing as cure, but more about avoiding TC and trans replacement under warranty.

[@JSC-c]

🙄 wish I seen this video sooner, Just had my 2017 Colorado done a couple months ago, and all they changed was the torque converter, good chance I’m gonna have the same issue happen again since they didn’t change the valves?

[@WholesaleAutomatics]

Possible but hard to tell, fit an i cooler as soon as possible as well.

[@WholesaleAutomatics]

So you have the same problem in the 6 speed LDV? And yes it is the same Colorado engine and auto so it does make sense. Being in Lilydale I would bring it in and Ask for Trevor to take it for a road test but he is away till next week.

[@aussieaaron1133]

I had my whole auto replaced because the clutch that does 3rd, 5th and reverse had shat itself, does that sound right guys.

[@WholesaleAutomatics]

Without seeing the transmission our self it's a little hard to diagnose what exactly went wrong with your transmission. Your issue is not that common but can be caused by more than one component. I would assume that when they removed the pan of the auto that is was found to have excessive ware.

[@waynebroderick5664]

How much transmission fluid do you put in a Holden Colorado 2015 RG

[@WholesaleAutomatics]

Full flush transmission service is about 15L while a simple pan of service without fluch is 4-5L

[@darrenwest2465]

When the valve in the front pump fails can this be picked up when they look at pressures with the diagnostic tool?

[@WholesaleAutomatics]

It is possible but as the transmission normally needs to come out in every case so we just upgrade the valve set and torque convertor regardless.

[@darrenwest2465]

@@WholesaleAutomatics I would have thought the faulty valve would be indicated by a reduced or increased pressure, I thought the valve body distributes the fluid to the correct location to engage the correct clutch packs etc. If the problem is reduced pressure is there a pressure switch within the TCM that would provide this information to the diagnostic reader.

[@WholesaleAutomatics]

Unfortunately the TCM doesn't register pressure, only slip if it is in excess. The trouble is that the lock-up is supposed to slip from time to time, a lot in fact so the TCU has a tough time picking right from wrong. If the valve is ever the cause the TCU runs out of pressure rise and even if maxed out, still not enough to apply fully.

Whats the cost to rebuild one of these like this im assuming aud?

Drop me an email at [e-mail] and I will send you some info.

[@newy1960]

Do you guys know what changed between models that caused the issues?

[@WholesaleAutomatics]

The torque convertor certainly changed but our new valve set suits both. The older convertor is in fact a little smaller as is the bell housing. Strange seeing that you would think the later convertor would be more capable and problemy is from a fuel efficiency point of view. The older valves do not seem to have the same problems also.

[@bobstewart7344]

Can you please advise.. The new valve has longer landings has the corresponding bore where the new style valve goes into have the longer landings ?

In almost every ase it is always the valve that just shows the wear. The landing seems to stand up a hell of a lot better than the valve does.

[@bobstewart7344]

Appreciate & Thanks for your reply. Can you just replace the faulty valves with the new improved ones??, is this a gearbox out to do this? Rob

[@WholesaleAutomatics]

Yes you can, but if you already have the shudder then change the torque convertor at the same time as the transmission has to come out to install the new valve set.

[@bobstewart7344]

Thanks again for your advice. You are champions Rob

[@Rawkus919]

How many dont have a problem?

[@WholesaleAutomatics]

Who knows exactly, you won't know until you are in the transmission looking at the possibilities. Certainly some of the worst case shudders seem to have but that can also be because the torque convertor is showing signs of being damaged. We have seen them with no valve damage and have also seen them shudder with replacement torque convertors where no valve upgrade was done. I don't know of a single case of shuddering once you have done both a valve upgrade set and billet torque convertor. Remember the pressures are also increased as part of the valve set to make sure we are covering the least explained cases.

[@jonathanpike5879]

Mine in for work 2017 only done 92000 ks got a shudder

[@WholesaleAutomatics]

Oh that is extremely common, We have seen them as early as 60,000K

[@troughlolly]

Hi, do the 6spd autos in the Isuzu Dmax 2017+ have the same gbox , if so , same issue? Thanks.

[@WholesaleAutomatics]

I am not aware of the problem in the D-max. Make sure you don't have a dodgy injector. It will do the same thing.

[@biastv1234]

Do you do change over transmissions ?

[@WholesaleAutomatics]

In many cases yes.

[@marcushegarty8778]

so can someone send this to all dealers that sold colorado,s, so owners have a better chance for warranty work, also ive asked about fitting one of your coolers & my dealer believes I dont need one, who do I believe

[@WholesaleAutomatics]

I sell oil coolers so from your point of view I'm jut a salesman. That being said if you tow or have kitted out the car with extra weight then yes it's a must have but if not the oil cooler will always make your auto last longer although problem won't help with the shudder.

[@killstrees]

Dealer just wants to sell more parts to you and the cooler prevents them from doing that by extending the life of the fluid and transmission, especially if you push your car hard towing or off roading a lot. If anything, it will increase the reliability of your car. I own a 2.8 Colorado zr2 in the States, and we have the same shudder issues with our 6 speeds as well. If we continue to use factory fluids, we cut the recommended change intervals in half, or we swap to something like Amsoil's Signature Series fluids, add a cooler, and we don't have any more problems. Tripple billet converters are also commonly installed as well. I personally have a cooler and highly recommend it. Temps are much cooler and never reach 200F (93C) any more. Our trucks are setup where 270F (132C) is the max allowed temps, damage is occurring well before that. I'm a heavy equipment operator, so do what you will with this info

[@michaelvandeelen7130]

Hi Orto, what would i expect to pay for such a job?

[@WholesaleAutomatics]

Depends of if we are doing the remove and refit of the transmission including transmission upgrade or if you are just sending the auto for upgrade or you are just after the parts. Email me on [e-mail] and I will get you sorted Michael.

[@haydenfoster9031]

Whats the cost of these upgrades?

[@WholesaleAutomatics]

You have three options: 1st We do the whole job including removing the transmission doing all the upgrades and reinstalling the transmission, 2nd You send us your transmission, we do the upgrades and return to you (this is the most popular) and 3rd we send the upgrade parts and you do the job yourself if you are handy with the tools, this is really only an option for someone that is either a mechanic or is confident working on their own cars. Email me at [e-mail] for more info.

[@KevyMillin]

Is this the same box as the Craptiva ? His auto refused to move at 175k km i said go back to Holden

[@WholesaleAutomatics]

No, it is a completely different transmission. The Colorado is rear wheel drive in transmission orientation but has transfer case so 4x4 while the Captiva is front wheel drive.

[@KevyMillin]

@@WholesaleAutomatics 👍

[@jacksonwelch9870]

⁠the service interval for the autos has been “revised” by Holden to the 72,000km or 75,000km interval depending on what schedule your car is on Not that that will fix the problem 🤷‍♂️

[@MSTAOZ]

What's it cost to do that, and where?

[@WholesaleAutomatics]

We have 2-3 options depending on where you are in the world. Email me on [e-mail] and I will get you sorted.
