Engine/Transmission (1998.5 - 2002) Shift Help PLEASE!!

[JSelf]

I started down this road over three weeks ago. My 1999 Dodge 2500 Quad Cab LB 4x4 Diesel was starting to want to stick in second gear upon taking off until I would let up on the gas... then it would shift and drive fine. Dealer says I need a new trans. I buy a rebuilt heavy duty one from from an aftermarket source (they have been great) and have it put in by two trans mechs after hours. Two days later same problem. I follow the Disconnect Negative cable 30 min, reconnect, slow pedal depress, and start. Truck shifts great until I shut it off. Then I have to repeat the procedure or it will stick in second. Is it the APPS or is it the computer losing the setting? Has anyone else had this happen? Oh Yeah I forgot to mention that when it is stuck in second I dont have a dead pedal. The RPM's will rev (I've only taken them to 2800) but I get little speed increase and no shift. When it is idleing the rpm's are a steady 700.

When the trans was swapped out, did they re-use the two sensors on the Valvebody? These are pressure sensors and transducers. They can cause the issues you have.



Did they change EVERYTHING but the bad parts?

My 97 did the EXACT same thing for almost 2 years, but not every time I drove it. It would come and go. I changed the TPS a few weeks ago and it has not doen it yet, but I have also only put about 4-500 miles on it since...

All new electronics in the trans. But... This morning the battery cable trick wouldn't work so I pulled the connector from the PCM and checked voltage at pin 23 (. 530 volts) I then checked the APPS and it said it should read . 580 so I adjusted it to . 581. Everything worked great for about eight shutdowns and starts, then tonight it started sticking in second unilt I would let off the gas. Does anyone else thing the APPS is bad or maybe the slop in the Accelerator cable is causing it to reprogram?
