Engine/Transmission (1994 - 1998) Whats the deal with irregular shifting in auto trans?

[CumminFast]

Hey everyone,

I have done a search and I cant figure out what the deal is with my buddy's transmission in his 95 12 valve 2500 4x4. He has a 47RH with triple disk tc and valve body and he has checked both batteries and cables and he has changed the temp sensor. Im stumped now. I have read about the rewiring kit that shendren has. Do yall think that this will correct his problem? Any suggestions would be greatly appreciated.

Thanks for the help,

Rick

Dirty TPS? Mine would shift back and forth. Cleaned the TPS and problem solved. Hope it's that simple.

Where do I find the tps connection and what is it?

TPS stands for throttle position sensor. It is located drivers side at forward end of inj. pump. Looks lie a small hockey puck about 3" in size with a connector at the bottom of it with three wires. It comes off by removing two screws through it and unplugging wire harness. Do a search for TPS cleaning and you will get a ton of info on it!
