Wait are you saying that once you connected F7 on the TCCM to the VCM (thing in board of battery underhood) that 4lo started working??

I studied and studied and studied this forum..... I struggled following it in forum version so then I typed up the outline...... (which with Racrx7 I will update with some of my own thoughts to clarify a few of the steps) I then followed it to a freeking T. I ohm tested every wire that I installed from end to end. I did ask a few questions along the way, especially about TCCM to PCM connection (which will be added as step 5 to the wiring instructions rather than leaving it in the Q & A at the end of the document)

I guess now it is time to update my signature with NP236 4X4.

Racrx7, have you determined whether it is best to drive from day to day in 2WD and conserve the encoder motor, clutch packs, and the axle disconnect emulator relay or drive in AWD as we all did before the conversion since we don't have the disconnect?

SG, I always leave mine in 2WD on dry roads, and switch to 4WD auto if I get caught in rain. This can be done on the fly with no issues or adverse effects on any of the system.

Trip south, The wire from the TCCM to the VCM, PCM, ECM, is only to correct the transmission shift points when in 4LO. Mine shifted into 4LO WITHOUT this wire being hooked up. The transmission just didn't shift correctly until I made the connection. That being said, the '99-'00 model with the 4 plug VCM looks to share this connection along with the front axle disconnect emulator circuit. so its possible this could be causing issues for some trying to make this work. It is imperative that the front axle emulator circuit, along with all other circuits, be correctly wired or the TC will not shift into 4LO.

Just to throw this out here, for those that may be floor testing all this before transferring into your van, make sure you leave the encoder motor ATTACHED to the case. If you apply power and try to actuate the encoder motor OFF OF THE CASE, toss it. Its now trashed. The hall effect switch plate inside will over stroke and become damaged.

And also run a decent sized ground wire to the TCCM case. The encoder motor reversing relays inside of the TCCM use the case for the encoder motor ground

I have spent the last 3-4 days just beaming that I got this running....,, I however can't escape the thought that all I did was follow great directions from racrx7 and captain crunch. Your time and effort to put this together and document how you did this is just amazing..... I would have never been able to do this if left to my own talent.

I can't wait to head to the mountains this weekend!!

Thank you!

Ryan
