Valve Body Cleaning

[@JohnSmith-wj2wd]

Thanks a lot for filming this. I was cleaning out a valve bore gunk with a few wipes of scotch brite and started to worry in hindsight that I may have damaged it since some people say that anything abrasive is an absolute no go, even though the bores look fine. It's good to see that you even hone them and sand the valves themselves.

[@CurmudgeonTransmission]

If you are very careful with them and don't get radical you can. Different things for different valves, but Scotch Brite is good choice. I would use it over sand paper in most cases. I only use a hone in most cases to get a sleeve to slide in easier. Thanks for watching.

THIS WAS SUCH A GREAT VIDEO! ONE OF THE BEST VALVE BODY CLEANING VIDEOS I'VE SEEN! 👍 WELL DONE! 👏

[@CurmudgeonTransmission]

Thanks 👍

[@TheOlewinski]

Thank you very much for your video! You really know how to explain things very well and easy to follow! If you don’t mind, I was wondering with your expertise if I could get your opinion…I recently lost R, 3 , 5 . When I removed the trans cover on my 2012 traverse and got to the drum. The wave plate was still there and looked ok. Could a not fully functioning valve body be the culprit of this loss of R, 3 5?

[@CurmudgeonTransmission]

It's possible you could have a vb problem. I would put the drum on the end cover and air check it. I would bet you have either a bonded piston problem or something wrong with the drum. Regardless of where the problem is, replace that cushion plate while you are in there.

Can you do a video on replacing bushings?

See what I can do.

[@bradmitchell2374]

What a great video, Thank you! I have an 06 Buick Lucerne with the 4t65e trans and I believe I may have a sticking valve. It has intermit harsh shifts but only has 1-3 gears, No 4th gear. No codes, fluid condition is good. Trans does not slip. Any recommendations as to which valves I should check or what other condition may cause no 4th gear other than the stripped splines on the hub? This model has the hardened shaft.

[@CurmudgeonTransmission]

Thanks. If it has no codes and no 4th the computer must not be commanding 4th. Are there ANY codes in any other module., not just transmission?

[@bradmitchell2374]

@@CurmudgeonTransmission I just recently purchased it, it had a p0300, p0442, p0128. I replaced the ignition control module and fuel cap an reset all codes. Engine runs great and no codes have reset after a 7 mile test drive. Manual 1-3 work normal (with firm shift). I believe there is only a 1-2 and 2-3 shift solenoid and no 3-4 shift solenoid. Thats why I was thinking possible accumulator or valve issue.

[@CurmudgeonTransmission]

So, it only shifts 1-3 manually? Has shift solenoid A & B. Work in conjunction with to create all the shifts.

[@bradmitchell2374]

@@CurmudgeonTransmission It shifts by itself in D or Overdrive, but just doesnt go into 4th. it also shifts manually 1-3 but not into 4th.

[@CurmudgeonTransmission]

Still could be a stripped clutch hub. There is a bulletin that states it may not throw a code even though it should. I have seen even the hardened ones strip.

Hi. This is really great stuff here. Thanks a million. Ive got an xc90 t6 which has a wiring / electrical issue we're diagnosing but I have a xc90 d5 as well with tf-80sc transmission which has flaring in 4th and 5th. I have normal shifting from 1-3 and reverse is fine but from cold, it starts with minor flaring, hitting 4000rpm in both 4th and 5th gears. I opted not to drive it and in the past, I've done atf draining and topup twice, since I received it, which greatly improved the performance. So it seems like the dirt is in the VB. Can you advise if this seems probable and I've heard about the updated vb in the 2008 xc90 but have no idea what this update entails.

[@CurmudgeonTransmission]

These valve bodies are horrible about wear. Will give you the symptoms you are talking about. There was an update around 2010 I believe if I am not mistaken. It also has an updated computer. They are not interchangeable.

[@nabeeljacksonrhoda6480]

@@CurmudgeonTransmission you're saying the ecu and VB has been updated? Also, since I'm getting codes for incorrect gear ratios and nothing else in the transmission, I figured this might be a case of overall cleaning up needed, gold old ultrasonic, demagnetizing and pressure spraying. No experience here, just learning and trying to understand as these are really my first experiences with owning automatic transmissions.

[@nabeeljacksonrhoda6480]

@@CurmudgeonTransmission looking forward to your recommendations considering my symptoms. Wish I was in the US to bring it to you.

[@CurmudgeonTransmission]

You really only have 2 options. The best option is to buy a new VB. If you want to buy all the reamers and kit to repair the solenoids you can go that way. You will spend more than a VB costs for the first time doing it. After that you MIGHT save money. I have done them. You only have about a 50/50 shot of it coreecting all the problems. And it takes a ton of time to do it. The only other option is buying one that has been rebuilt. If you are going that route I would buy Sonnax. There are other people that sell the tools, you will just need to do a search. Here is one you can check out. maktrans.ae/09GSBTOOL

[@mikeenglish3936]

Sir, i have a U151E, it just started slipping and ramming back and forth into gear, then it lost all front gears but reverse worked, i got an overhaul kit with friction clutches and steel plates, new gaskets, orings, seals etc, after the mechanic replaced them all, it was still doing the same thing, transmission fluid had never been changed before but could a clogged valve body be the cause? If he cleans it do you think it it could come right? Im in debt, i cant afford to buy a new transmission, im praying it works.

[@CurmudgeonTransmission]

It's a good possibilty that there are valves stuck in the valve body. Especially if the planetaries broke like they usually do.

[@Sundog0811]

Can you come show me on my vehicle?

[@Devo1987]

Are the automatic transmission valve bodies on a 2006 mazda 3s tend to get dirty ? Would you know what parts fail the most on a 2006 mazda 3s automatic transmission ?

[@CurmudgeonTransmission]

When parts fail, they all do. These tend to wear out the servo bore for the band. How long it gets driven after that will determine how much damage is done.

Copywrite strikes are stupid especially when its a stupid on radio 50 feet away and its a 20-year-old song and depending on when tom starts his video its not even an entire song, and you cant even hear it sometimes over your voice, i mean seriously some people need to get a real job like what Tom does here day in day out, i mean for fucks sake they have full leghnth videos on you tube of regular people using an entire song and they made thier own version of a viseo for it and you know dam good and well they didnt get permmission from the artist to use it, yet if a radio in this transmission shop plays 12.7 seconds of some 30-year-old song OMG! its a NATIONAL CRISIS! really? who cares? its truely amazing what some people worry about. many artist and groups i listen to are no longer even alive smdh

Feel the same. Should be happy someone is playing their stuff. Someone may here it and think hey I like that and then go buy it. Free advertisement as far as I am concerned.

[@michaeljohnson91501]

So I have codes for transmission fluid pressure switch low..I thought it was the laminated disc's but they look fine...could gunk buildup inside valve body cause this?? It's a 6l80 for 07 escalade

[@michaeljohnson91501]

Codes are p0842 p0989 p0877

[@CurmudgeonTransmission]

It could be a few things. Those switches tell the Techm when the gear it has commanded applies. If it doesn't do it then you will get a code. So it either has not applied or it thinks it hasn't. You can plug the Techm into the harness and watch on the scanner to see if manually pushing on the switches to apply them changes their status. If they still don't then you have a bad Techm, if they do you have a problem in the transmission or valve body.

[@ayebabyboo1184]

Are you using pure water

[@CurmudgeonTransmission]

No it's a type of mineral spirits that Safety Clean provides in their machines. Not sure what grade it is. Never asked them, guess that is a good question the next time they show up to service the machine.

[@howardlovecraft750]

From your experiences with C6 transmissions, would this procedure remedy a transmission that won't go into 3rd? I've got an 87 f150 that sat for about 8 years that has only 56,000 miles on it, so when I bought it I flushed out the old fluid and it ran good for while then all of the sudden no 3rd gear. What's usually the fixes with the C6's in your opinion? Thanks.....Good video too.

[@CurmudgeonTransmission]

Thanks. Do you have good reverse? Is the 1-2 shift on time?

[@howardlovecraft750]

@@CurmudgeonTransmission Yes...reverse works good and 1st and 2nd gears shift right on time as they should, there's no shift into 3rd almost like it;s in limp mode.

[@CurmudgeonTransmission]

We rent ours from Safety Clean. They use some kind of mineral spirits mixed with something else to make it less harsh. When I first started we used mineral spirits and added transmission fluid to it. Some people use brake clean. Some use B12.

Why do transmission shops always try to replace the entire transmission as opposed to simply doing this?? At any rate, excellent video. I look forward to doing this as a diner. Any advice for those that want to do it themselves?

[@CurmudgeonTransmission]

Take your time, take pictures and mark they way things go. Lube and Aerokroil are your best friends. Small brake hone, fine sand paper and Scoth-Brite are a close second. Thanks for watching.

[@ZBrink11]

Cause they don't actually want to do work. They just want to swap.

[@scotgustafson3270]

If you are operating a transmission (or any mechanical) shop, you want the job done right the first time. First of all, if the "cleaning" only fixes the problem for a few weeks then the customer is going to tell everyone that you do bad work. Second, When they come back in a few weeks (after insisting you do the "cheaper" repair) they are going to expect you to warranty your first quick fix. Come-backs are a way to go out of business fast. This video instruction is for the do-it-yourselfer that wants to try to avoid a costly rebuild and get a little more life from an aging transmission.

[@spencemcmorris7686]

If I use pure water will that cause problems later??? I was planning to blow it dry and then use my heat gun to dry up as much as I can get with those two methods.... also considering just some brake clean and blow dry and call it a day. Never done this b4

[@CurmudgeonTransmission]

Of the 2, brake clean would be better.
