Transmission went BOOM!!!

[Rollin Thunder]

the 4L60E is designed to hande 360 FT LB of torque and the 5.3 liter is rated at 340 FT lb of torque, a tune puts you right at that mark.

That's why GM puts so much "torque management" in their stock tune. Pretty sad that this is their answer to a transmission that is not up to the task, just restricting the power to it.

well its sad that it was 2009 before they did anything about it (putting a 6l80E in its place)

That 4l60, 65, 70e's are junk.. JUNK and GM knows it that's absolutely the reason for the torque management in there. Long live the 6l80e!! All you did by getting a tune was speed up the inevitable with that junk. it's like the ol' 50/50 chance of getting one that aint gonna break by 50k miles..

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

do a burnout in front of the service center when you get her back

Wel atleast you got your way, my tranny has not seemed to give any signs of issues, but then again i'm only at 19500k miles.

i wish i could, this thing can't burnout to save its life.

This Tahoe came with the 20 inch rims with a 3.42 gear ratio. i was thinking that was part of my problem, putting more load on the trans

I bet it wasn't the tune, just the stinky GM trannies.

Well we will see how the new trans holds up. i have 70,000 miles left on my warranty.
