Ok thank you! I will give it a try

The governor pressure sensor and solenoid are only about 4 months old, but I know even knew parts can fail. So, you are saying next time it acts up that I should select 2nd gear and see if it starts in first?

So, when my transmission gets up to 140 degrees or warmer it will not downshift to 1st gear when coming to a stop. I can manually downshift to 1st gear then place the shifter back in drive and it'll work like normal. When the transmission temp is below 140 it downshifts as it should. The only mods to the transmission are a transgo shift kit, borg warner governor pressure solenoid, and a BD Diesel transducer upgrade. I checked the tv cable, but it was already adjusted properly. What could the issue be?

I ended up swapping the transducer and wiring harness inside the transmission which fixed overdrive and lockup.

I am almost positive the 8 pin connector on both trucks are the same. I just ohmed the trans temp sensor in the 97 transmission and it reads 1k ohms then I ohmed the trans temp sensor in the 01 transmission and it reads 2k ohms. Does anyone know if they will interchange?

I recently bought a 2001 4wd Cummins with an automatic transmission. The transmission was slipping in 2nd gear, but all the other gears worked great including overdrive. I swapped a 2wd transmission from a 1997 into the 2001 and now I do not have overdrive. I drove the 97 before the swap, so I know all the gears worked. The swap consisted of installing the 4wd overdrive housing with transfer case on the 2wd transmission, and I had to swap the neutral safety switch due to the plugs being different. I have checked pin 6 (brown wire) at the transmission plug and it has a constant 13-14 volts when driving the truck. The pcm isn't sending the signal to the overdrive solenoid. Where do I go from here? Is the 97 transmission temperature sensor different from 01?
