Summary:
THIS VEHICLE IS BRAND NEW.
WE ARE WORKING ON THIS FOR OUR LOCAL DEALER WHO IMPORTS THEM FROM THE STATES AND CONVERTS THEM TO RIGHT HAND DRIVE.
TRANSMISSION DRIVES FINE WITH TOW/HAUL SWITCH ENGAGED.
WHEN SWITCH RELEASED WILL BIND ON 3-4 SHIFT (ATTEMPT) AND GO INTO FAILSAFE SETTING CODES LISTED. EVERY TIME.
SOLENOID ASSEMBLY HAS BEEN REPLACED. FAULT STILL THE SAME.
WHEN CONDUCTING TRANSMISSION ACTIVATION TEST WITH DEALER SCAN TOOL, UNDERDRIVE SOLENOID ACTIVATES BUT UNDERDRIVE PRESSURE SWITCH DOES NOT CHANGE.
WE HAVE A LOOM PLUG ON ORDER TO FIT THE TRANX TO ELMINATE VEHICLE WIRING OR TCM.
ANY HELP FROM YOU GUYS IN THE STATES WOULD BE VERY MUCH APPRECIATED.
WE HAVE VERY LITTLE INFORMATION OR KNOWLEDGE ON THESE TRANSMISSIONS HERE.
REGARDS JASON
