Hey I’m new to this forum and haven’t really used one before so here are my problems and questions well to start off I bought this 2000 Dodge Ram 1500 short wheel base 2wd it had the 3.9 magnum well I replaced the 3.9 with a 5.2 magnum I used the pcm and wiring that went to the 5.2 well my problem I’m having is the truck starts and run you can rev it up but I have the famous NO BUS and my dash and I have the transmission temperature light on and the O/D light saying off and seems like the truck doesn’t have any power when trying to drive it ok so my question are is the auto transmission going out and what could be causing my problems thanks in advance
You have an electronics mismatch. What year was the PCM/harness from?
Moving this to 2nd gen ram section for ya. Welcome to DF!
The truck is a 2000 model it did have a 3.9 I removed all wiring that went to the 3.9 I replaced the 3.9 with a 97 model 5.2 I used all wiring that went to the 5.2
And thanks for moving these for me I really appreciate it and thanks your responding and I can get pictures of everything if y’all need to see what I’ve done
That's not gonna work, 1997 had a different instrument cluster with a mechanical odometer vs the later models with the digital one. You need a newer PCM. Also, did you swap the transmission with the engine ?
I have the whole cluster out of the 97 will that help me any
No.
A LOT changed in 98, some more changed in 98.5, and yet more changed in 00. You need a pcm from a 98 or newer truck, and it will need to be flashed for the correct year/size engine/trans.
