I have a 2007 3LT 2WD with 31,000 miles on it and last weekend i was driving it at about 32-35 mph and all of a sudden i hear a loud POP and then the rear tires locked up for a second and then let loose, when i tried to accelerate i had no forward gears, reverse works but it make a ton of noise and locks up every rotation. I have never towed anything with it, its pretty much stock except for exhaust. I took it to the dealer and i am waiting for them to call me and tell me what happen. i will give an update as soon as i have one.
Has anyone had any transmission problems like this?

 

are you sure that it is the trans?

 

sounds like the tranny to me... sounds like warrenty!

 

Welcome to the forum.

Keep us posted. Doesn't sound good but should be under the 5yr/100K warranty.

 

Thank you very much.

Update: The dealer called me today and said that the output shaft was what broke and that they are installing a new trans.

 

that is kinda crappy the transmission's are going out that soon. Mine lasted 152k in my tahoe

 

I got 285,000+ out of my old one, i sold it at 285, and the tranny was fine... i better get at least that out of the new one.

 

Update: #2 Well i picked my Tahoe up from the dealer with the new re manufactured transmission in it, The truck drives good but there is a big slip between 1-2. 2-3 feels ok. I guess i will have to put the BB TCM back in my truck ASAP. But all in all i am very satisfied with the service from my dealer.

 

You're easier to please than me must be. I would not have accepted a reman ona 31,000 mile truck.

Also if this one doesn't have a good 1-2 shift, I'd be back for a new one.
