Pulling the 360 and 46re out of a 99 sport 1500 2wd, I have the 4bt and a 47re to go in....

The questions....

are the plugs/harness the same between the 46 and 47?

Is there anyway to program the 1500 PCM to shift the trans at a different rpm with something like superchip or hemi fever tune?

Worst case I will get a 98 12v cummins harness and pcm but if I can make the gas electronics work, it will be a huge time and $ saver

 

Trans plugs should be the same.

Not sure you will be able to convince the gas PCM to run things. It is going to be missing some inputs that it wants.... (cel will constantly be on)

Another member did this swap.....

 

getting the pcm to work wont be an issue, just the shift points will be, i ran my 98 12v on the v-10 harness and computer for a bit, that stuff is simple for me, and the cel can be "fixed" :-) thanks for the link ill do some reading but looks like he went with the RH trans

 

here are a few pics

picked up the 99 sport 1500 2wd for $800 runs and drives great and still registered, couldnt pass that up, traded a old 454 for the 4bt, bought a complete rebuilt 47RE for $500, and have a few parts rigs to pull the power steering/vacuum pumps, intercooler and piping, and all of the other little stuff, with any luck this thing will look and work like it came from the factory this way

day i picked it up



changed tires wheels and both bumpers



and the 4bt.... wish it was a p-pump, but the a-pump will do just fine

 

I *think* the PCM will want vehicle speed, engine RPM, throttle position, and possibly engine temp to run the trans, that may be it.... try it and see I suppose.

 

ya i got the rpm and the tps covered,the vss will remain intact, and the temp sensor i will just swap from the 360 if the ohm's are different from the cummins sensor

 

I would think that would be enough for the PCM to run the trans..... Maybe MAP sensor as well.... (which would make your life really interesting.....)

 

well... im about 99% sure the map doesnt have anything to do with trans control, but thats one of the things i will probably hook up and install just because its simple to do, i know it will be reading boost instead of vacuum, but i know a few boosted gas guys that dont have any issues with that part of the mess

depending on how many codes this thing throughs with the minimum sensors hooked up, i may install some dummy sensors and/or resistors to keep the CEL off, but if its not feaseable, i'll just pop the dash apart and disable the bulb

 

Nice project! Gotta keep us updated...

 

will do! hopefully pulling the 360 and 46 out this weekend (weather permitting) and with any luck, will have the 4bt and 47 mocked up in the truck, from the looks of it, the 47 should bolt in with out any cross member or drive line mods, but we all know how that goes... then got to figure out the engine mounts, im going to use some 2nd gen 6bt engine mounts as to not modify the frame, just have to come up with some sort of an adapter plate to bolt them up to the engine
