4l60e problems....any ideas? Okay, so here is what I've got going on...I literally just got a tranny rebuild. Everything was replaced in it. But when I take it out to drive...It shifts higher than normal. It will shift to second at 2500, third at 3500, and fourth at 5500. And while driving on the highway it has no passing gear. I was told it might be the TPS...but I don't know...any help appreciated....I'm not a transmission guy at all

4L60E shift points are totally PCM controlled so TPS is possible. Is the Speedo working ? Certainly it is a control issue.

Just for giggles have someone watch the throttle body cam while the gas pedal is pushed down (with the engine off of course). Make sure it's going wot. The TCS cars sometimes have the cable slip out of adjustment and the pcm tries to run off of cruise tables when you think you are wot.
