NV3500 manual swapped Durango ~ No Crank
Hey guys!
ive been digging and digging for the right info and im falling short of finding it.
ive already swapped the 45RFE out for a new flywheel, clutch kit and NV3500. Starter for the NV3500 installed. Transfer case bolted right up and my custom rear driveshaft installed.
i know i need to wire up the reverse switch and it wont take much brain power to sort that out, but which wire/wires do i need to ground or loop etc to get my truck to start? I have the full manual but id rather do it right the first time and not screw anything up. Im fairly certain on the 45RFE the wire(s) in question are in the big bundle that used to attach to the valve body… As all other info related to this topic for different transmissions list a 3 prong plug as the target source… Which the old 45RFE doesnt have.
HELP?
i do not plan to install a clutch safety switch. I want to bypass that whole circuit.
As a matter of record this is on a 2000 Durango SLT 4x4 4.7L with the separate pcm from the ecu.

This is just speculation but I believe the 45RFE uses a range position sensor instead of just a plain NSS switch at the transmission, so the PCM is actually looking for range position and then generates the starter lockout signal from there on whether or not it will allow the vehicle to crank? I'm not sure how factory you want things to be, I would be tempted to just run a separate starter button right to the starter, or hijack the ignition switch start wire mid harness and send it to a mag switch and down to the starter.
Im not sure I follow your pcm ecu statement, you are running a standalone ECU for the engine, or you're just pointing out this truck has a PCM and ECU separately already from the factory. Which yes if IRRC the 45RFE/545RFE had a separate TCM, It may be possible yo hijack the NSS from the TCM but I'm guessing that's all data link from there. If all the auto wiring is in place I might also be tempted to try plugging the range sensor back into the harness and locking it in the park or neutral position but that could be unreliable.
