Trans slips when it goes to 3rd

[obzidian]

yeup, sounds like your 3-4 clutch is burnt or going, soon.

unfortantely, the 4l60e is at its limits with 345hp and almost 7klbs. Even in my stock camaro, i had it go on me. I never really abused on it, its just heat, poor oil lubrication, sprag count, etc.... its makes the trans prone to failure. I had hoped the H2 came with a 80e but whatever, i guess we need the gearing of the 60e to get this thing of the line.

anyways, with your warranty ok, you should have no problem with the service. I wouldn't expect to pay a cent with something like this. If anything, you could add a decent trans cooler and with some practice, that trans will live a bit longer. One thing for sure, try not to go in 4th/od gear at or close to WOT. Also, never manually shift on the street and try to avoid as many 4-2 and/or 3-1 gear shifts.

good luck!!
