4L60E Teardown, No 3rd Gear

[@daveunbranded]

The customer is very lucky to have you. Most companies would not warranty that.

[@automaticosdovale-cambioautoma]

I'll work one of this tomorrow! Thanks for sharing.

[@keltecfan]

Hello Gary. Have you considered a caveat added to each work order, requiring a 2 week follow-up that requires the customer to bring the vehicle back to your shop for a test drive & inspection for leaks? That's the way we did it. There was a space on the invoice that required a date & signature to verify compliance. It might've caught this leak early enough to correct it? Just a suggestion. Thanks for taking the time out of your busy day to make these videos.

[@GaryFerraro]

We do that with Retail, alittle harder with wholesale to have them contact the client to bring the car back, sometimes even the retail clients do not show when we ask them to come back. Thanks for the suggestion

[@lukestrasser]

Sucks to have a comeback especially when it wasn’t really your fault. With the quality of your work it probably doesn’t happen very often. Cheers.

[@GaryFerraro]

Not to many issues here thank god.

[@kevinortega7810]

I have a 2007 H3 at the shop I work in. Replaced the trans and got the input speed code...assumed the junkyard sent a bad trans so had them send another and got the same code . Does the 07 have the separate TCM?? I'm getting some information says 07 up does and some says it's 08 and up??? I'll be looking in the morning. If it doesn't have the separate TCM what's the fix for the code??

Thank you Gary!

Great video, thanks for sharing it! I have an early 4L60E with the 3-4 burnout issue in a corvette i just picked up. I plan on doing clutches and steels yo run it the rest of the summer. Is there something you see that's a common contributor to this issue, or is it mainly a weak point from the factory?

[@GaryFerraro]

what year is this

[@Samll19821]

Hi Gary 2011 yukon Denali 6.2 motor, wich transmission has this truck? Torque converter is so noisy and going forward goes to 5- 6000 rpm.

[@GaryFerraro]

should have 6L80, converter going bad is common

[@Samll19821]

Should I take transmission apart and inspect or just replace converter? thanks for your help.

[@GaryFerraro]

@@Samll19821 I would drop the pan and see how much debris is in the pan, probably will need to be overhauled

[@Samll19821]

Thank you, as soon weather gets better here in minnesota I'm going to start with that project . My 5r55s still running after replacing overdrive sprag 4 years ago, your videos helps a lot.

Hallo Garry Im an your fan from italy I want ask you a problem i have with an 4l60e from an gmc sierra than 1999 , 5338 ccm 199 kw Lm2 motor number I lost the big checkballs on the gearbox accumulater I need measure of checkball The little checkballs are 6,27 mm

[@tptrsn]

I love your videos sir, so much so that if you were willing to consider getting a new camera, I would donate $20 toward it! The content is fantastic, and sometimes it's a little hard to see what is happening on that camera's image. Shoot, I may even have one I could just send you that is better than that one. What is it?

[@GaryFerraro]

I have a samsung. What brands do you recommend?

[@tptrsn]

@@GaryFerraro Samsung has made some really great cameras, but they seem to have gotten out of the business of making video cameras for the most part I think. So from the look of the image, I'm guessing that yours might be a camcorder that is pretty old at this point? I guess on the whole, there are a lot of small Sony camcorders from recent years that would be a pretty big upgrade in image. I usually use bigger, interchangable lens cameras, so it's hard for me to give a solid suggestion on a recent camcorder that would be one of the best ones to choose. My impression is that there are lots of recent models from Sony, Panasonic, maybe Canon, and maybe even Samsung that might be good options... If you did want to move to an interchangable lens camera, which would be a lot more expensive, and probably a lot less convenient to use, then I could actually offer suggestions.

[@tptrsn]

@@GaryFerraro I explained in my other answer why I can't offer a really good suggestion that is right on point, but from looking at what Marcuspix on KZbin has to say, I think I might be inclined to try a Sony CX405 for taking some better videos around the shop. It's not super expensive if it gets ATF or trans gel all over it or whatever, and does a pretty nice job!: kzbin.info/www/bejne/gZ69eWaofM-dorM

[@JBBRAD9267]

I am shocked at that fluid after just 8 months. Also you said they added fluid to drive. Why is it so nasty already?

[@Mr.BodyByFisher]

Will a new torque converter be needed after such a repair and was the part you replaced in the rebuild where you said it shouldn't do that and could it led up to the problem of no 3rd Gear

[@GaryFerraro]

Technically no, but if the fluid is really bad and a lot of debris in the pan you may want to consider it, can't really get them clean inside

[@Jus4Fun-j3l]

What does it mean when your 4L60E won't shift from 2nd to 3rd but only sometimes? Never slips and no codes.

[@GaryFerraro]

possible hanging 2-3 shift valve, maybe solenoid issue as well

[@mistermr2147]

Awesome channel! Do you guys replace bushings as well?

[@GaryFerraro]

Bushing when rebuilding the trans?

[@mistermr2147]

@@GaryFerraro Like the bushings for the shifter on a manual. I have a lot of play when shifting gears and it feels very sloppy.

[@smpropertymgmt6479]

What was the cause of 3rd gear failure? Could it have been a leaky check ball & capsule that lives inside the trans. case?

[@GaryFerraro]

Never really found the smoking gun, i did check that and seemed ok, put in new 3-4 piston, double checked the Boost valve, no leaks, put ne rings on input shaft, everything air checked good and the drum held pressure, so went back together with it

[@thechaindude1320]

more than likely was slipping due to low line pressure as a result of low fluid level

[@unclecowboy2003]

Will a 1999 4l60e out if a 1500 Chevy truck work in a 2007 4l60e 1500 avalanche

[@GaryFerraro]

No, Units are different

[@unclecowboy2003]

@@GaryFerraro ok is it the speed sensor inside I just counted the pins one is thirteen and the other is fifteen I believe

[@JBBRAD9267]

Thats a 4l65e not a 4l60e

[@e559]

I have a stage 2 tranny that i installed about a year ago and recently my 3rd gear started slipping so i check my tranny fluid and i ended up being short like 3 quarts so i did research and im guessing its the 2-3 clutches, should i replace all clutches and steels only? Since it was kinda low on fluid what should i look out for when im replacing them?

[@GaryFerraro]

you can, as long as it air checks ok. Check the pressure plates, check the snap ring, load up the new parts and air check, if solid you should be ok, If a lot of debris you may want to take the drum apart for cleaning

[@igotaction]

That is a bummer.

[@GaryFerraro]

It Happens, not to often thank god

[@DustinKeating-yk3vq]

If yall just done work on the transmission why did it leak enough fluid to mess it up so yall pit a leaky transmission back in the mans truck

[@GaryFerraro]

I'm sure it developed a leak

[@StevenSimpson-vy4bq]

So what would cuz one to have no second gear

[@GaryFerraro]

If your working with 4L60E That is the band

[@StevenSimpson-vy4bq]

@@GaryFerraro I have done a full rebuild on this unit it's being commanded for second gear but when it goes into second gear it just runs away even put different valve body in and still have the same even done the Corvette servo I am lost on this unit any help would be appreciated

[@SickleCellSuperSaiyan9000]

Hahahaha like a 4L60 sooo true

[@mails5054]

What is your most liked "older trans" and most hated. Trans that have been used for awhile(even if still used today).

[@GaryFerraro]

most liked is 4L60E, most disliked is 5L40E

[@thechaindude1320]

any experience with the AW55-50sn? I'm curious how many of these you've done these and at what mileages. I have a Nissan Quest at 156k with this transmission and unfortunately it is succumbing to the infamous 2-3 shift flare.@@GaryFerraro
