Hey guys. I have a 99 A4 Z28 with blt ons and a cam. It shifts from 1st to 4th on occasion, not all the time. It also is throwing a TPS code, but I checked that and it seems okay. I logged some driving and looked at the map and tps voltage and it all looks okay. The calculated load was only at 30-40%, but I dont know what that is supposed to be or if it even matters. If I hit it off the line it will go for a little, then hit 4th and fall on its face like it isnt even accelerating anymore, then after 5-10 seconds or so it will take off again. If I manually shift I have no problems. Any help is appreciated.
