1997 cummins 12 valve engine computer

Guys I am currently restoring a burned out 1997 3500 and was wondering are the manual computers interchangeable with the automatic ones ? my parts truck was a stick and my burnt one is an auto.

No, the PCMs are different between the 2 since the PCM controlls some of the transmissions function (lockup/od).


As far as it getting the truck running, yes it will. The PCM only controls the charging and grid heaters as far as the engine goes (because of course its mechanical injection)

If it was me I would try it and see if it worked I swaped to a manual and still have my auto comp and it works. With the only other things the comp controls is the charging and heaters I dont see why it would not work to run just those unless the wireing to the main comp plugs is differant.

It will definatly run just may not charge or heaters may not work.

i think that the controllers themselves are the same, it's just the programming on them that are different. that's why they have to have the VIN programmed into them so that the correct software can be programmed into the controller

It probably wouldnt be too hard to have it sent out and 'reflashed' with the proper software. that is, if they are the same hardware internally.

It doesnt make sense that they would use 2 completely different PCMs just becuase one app requires a few extra basic functions. (it would probably cost them more money to use 2 different PCMs with different internals than what they would save for the electronic parts)

But ya never know, since when have any of the auto makers made any sense?

Well I was cleaning out under the hood last night. It is unbelievable you can't even tell what was what after a fire. It is just a big pile of melted junk. anyways the automatic computer is junk kinda toasted so the manula will go in to run the truck. I have leads on a 1997 auto computer the guy bought an engine with harness and computer and is only using the engine so I may have lucked out.

thanks guys
