Just picked up a 2001 dodge diesel with an auto transmission. Main issue is not going into overdrive. It also doesnt want to shift down into 1st when in drive, so you are basically operating in 2 & 3. It will go into 1st if you put it there manually though.
The weird thing is that I spoke to the previous owner (last guy that actually owned the truck and drove it), and he said he never had ANY issues with the transmission. He had issues with the fuel pump, so he changed that out, but didnt wire it in right so couldnt get the truck to run. He sold the truck as is to a local shop that said they wired in the fuel pump right and sold the truck to someone else. I just bought it from him. So it is from that point forward that the transmission didnt work properly. Previous owner says the only other variable he could think of is he had a mild smarty tune in the truck which he took out when he was working on the fuel pump. So I put the tune back in and no difference. Took it back to the shop that had bought it and fixed the fuel pump for a diagnostic on the transmission. Charged me 160 to tell me that the solenoid was recieving the signal from the pcm to shift into overdrive, so maybe a bad solenoid. Said to change that one, and the one that commands the shift down into 1st.
The timing just seems odd on this issue though so thought I would throw it out there to people more experienced than I
