Quick background...07 Tahoe LTZ 125K. Lost my 3-4 clutch pack at 95K and rebuilt tranny myself. I replaced everything except the valve body separator plate. Tranny has been working fine up until last week when the Stabilatrak light came on for about 30 seconds and then turned off. After that it started shifting into OD slowly and there is a small amount of shudder when it does. I took it to the dealer and there are no codes. Dealer is baffled. Talked to a tranny shop, they think the clutch band wore out. But it shifts into 2nd just fine. So I doubt thats it. Any ideas?
Oh and the tranny is running about 10 degrees warmer. It used to run about 195 degrees no matter what temp it is outside, now it runs at 205
