Okay this is in my 2002 Silverado. 4L60E with billet servos, TT3000 TQ, and TransgGO shift kit. Install servos around 6 or 7 months ago, intalled stall 2 1/2 months ago , and installed shift kit 1 month ago.

I knew this was going to happen to me sooner or later, but why now?! Truck will not stay in OD. I have to give it gas for it to shift in to OD, and as soon as I let off the gas, just the slightest bit, it will go right back into 3rd. It also felt like it shifts into OD too soon before, when it acctually shifted into OD.

Also my 2-1 down shift feels funny. It will shift down and then shift right back up and the motor will bog. What is this all about?

Do I need a rebuild (or a 4l80) or do you thing I could have done something when I did the shift kit? It seemed all fine right after this last install.

If you have, or know some who has an OBD-II scanner, take a look at your TPS values over the entire throttle range. It really sounds like the PCM is getting bad throttle position data.
