- Make sure shift linkage isn't rubbing on NSS harness if you haven't already

- Verify NSS is hooked up properly under the hood

- At this point I would just unplug NSS harness from the trans , pull it up into the engine compartment and isolate it from any metal.

!!!!MAKE SURE CAR IS IN PARK!!! Then jump the start solenoid and fire up the car.

Hop in and run it thru the gears and see what happens.
