97 k1500 4l60e transmission help

[Dannothemanno]

I just got my transmission rebuilt about half a year ago and I seem to have a issue where when I'm driving around 45 and up the rpms seem to drop around 1200 rpm and stay there even while accelerating unless I step hard on the gas. so far I've replaced the tps and brake switch and nothing what else should I check?

You say you have replaces the TPS but did you test it first? My simple obd2 computer can test the TPS and show it in graph form. I would double check it if you can. Before I knew about the computer test..... I thought my tps was fine while chasing a hesitation. I swapped it and didnt notice a difference so I put the old one back on. It turns out it was actually a failing new delphi fuel pump. However while screwing around with the computer I see this tps test.... i giver a go and notice a very small break in the graph line.... it is no good. So I put the new tps back on and tore ass outta my drive way like a brand new sports car.

I love my truck! People look at me funny when they see my old burb launch at a red light. LOL. puts a smile in my face everytime.
