He is small so completely at the mercy of when he can get tranny shipped to him. Also a 1 man show. It was a second truck for my business so it wasn’t urgent. Guess that may not work for everyone, lol. Good luck, but yea, vehicle problems suck!

GH I've been waiting on two 6 speed transmissions from GM for 3 weeks, they're a hard get right now.
Supply is just a cluster fk across the board for just about any parts right now.
Goodluck hope it works out in your favor.

A rental is going to cost me as much as the repair.

Trucks end up in lakes all the time when launching boats and have to get totaled baw. Those guys probably get a new one in less than 3 weeks.

These responses are really making me glad I went with a Tundra last year.

Wish I still had a 2nd vehicle I'd loan it to you.

It might just be the clutch solenoid or something like that. I wouldn't right it off as needing a new torque converter just yet. You an drop the transmission pan yourself and see if there's any evidence in there like metal, sludge clutch material etc.

If you dig around and want to do it bad enough, you can probably find a 6L60E troubleshooting guide online and get after it.

I did a 4L80e rebuild myself once. Didnt last very long. Don't get too deep into that thing without the right stuff. Dropping the pan is no biggie, even taking the trans out and putting a new one in isn't too bad. Just don't take the guts out of the trans

Greenhead,

I just noticed your signature.

It was painted by a guy named Chig Biggers.
I knew him pretty well. He was pretty good friends with my dad.

Appreciate, and yea I don't think I'll be doing any work on myself since I am currently in Houston for work. Going to drop it off today at a transmission place for a diagnostic. I am hating to do it but can't afford to get stranded halfway home, especially with the whole interstate being torn up from Houston to Laff with construction.

Just dropped a trans on 2015 Sierra 6 speed at 153k miles two weeks ago. Similar symptoms as yours.

How soon would it have had to happen to be considered "too painful"?

My dad's 2018 GMC was having similar issues...I think there is a service bulletin of some kind concerning a trans flush and fill...specific number of times and certain fluids.

TSB about Trans

I think that's it.

Some say a temporary fix but it's currently working on his truck.

TCC shudder.

Get tranny checked and it is likely as simple as a fluid change.
