That whole thing sounded weird.Hi guys,
Just finishing up my 3.9 to 5.9 swap in my 99 Dakota. All good, easiest swap I've probably ever done except for one little problem. I'm having absolute hell trying to find a 46RE to replace the 42RE that was behind the 3.9. The current trans was/is working fine and I figure I can keep on using it while I continue looking for a replacement. Here's the problem:
I now have no overdrive or TCC lockup. Had it before and I made no changes to the wiring harness other than add for the extra injectors. I had the donor computer reflashed by B&G and according to Dave the PCM will not support the 42RE - he set it up for the 46RE.
To add to my pain I don't have a FSM handy for the 99 - I do have one for a 98 Ram and I have seen some differences in the wiring, though not in the pinouts. So here's my question for any of the transmission experts out there:
The OD and TCC lockup for the 42RE are controlled by the PCM (I've isolated them through to the 8-pin connector on the trans). Is the 46RE OD and TCC controlled differently? Can I re-pin the PCM connector to get the right signals to the 42RE 8-pin connector? Or am I missing something?
