Auto to Manual swap 98.5 & 2002 - Competition Diesel.Com

Turbonetics TQ · 08-03-2022, 10:01 AM

I am looking for a little guidance, and/or suggestions.
The swap will happen between a 98.5 manual and a 2002 auto.

So the 98.5 will be going Manual to Auto
The 2002 will be going Auto to Manual.

Both trucks need to be up and running afterwards.
I have done a lot of reading on the subject and a few items that I could not get clarified are as follows:

-Engine ECM: Will the 98.5 manual ECM need to be reprogrammed?
*if so, is this something the Dodge dealer can do?

-Gauge cluster: The 98.5 will need the PRND indicator, can it be swapped from the 02 so the mileage stays correct for the truck. (or does the entire cluster need swapped)

-Wiring harness: I know I will need the PCM/trans harness' swapped, but will the PDM (fuse box) stay in each truck?

I have a pretty firm grasp on all the main items required to swap the transmissions so I am not asking about all that. BUT if there is something you have run in to while completing this procedure PLEASE let me know.

Thank you,

Might want to reach out to Mark Nixon about specifics

I don’t think the 02’ pcm can run the 98.5. Something about the early 24v does or doesn’t have a cam or crank sensor. The 02 auto ecm/pcm won’t care that the auto trans is missing, at least my 01’ could care less. Anyone with a good scanner should be able to reprogram the odometer. The autel does. I assume both trucks are the same body style otherwise you’ll be making driveshafts .

PCM’s will be swapped and ECM’s will stay in place.

But if the 98.5 is rear wheel abs only, the 02 is 4 wheel abs it wont fly. The 98.5 is a differnt tranny harness setup compared to the 99-02 too.
