All Thanks, Donations and Support to Shift Kits Australia for their Assistance
Installing 3.7, 3.9, 4.11 to AU will throw your speedometer out
Installing a Correcter behind the cluster to adjust the speedometer back into real time will result in your transmission shifting incorrectly across the board and Torque lock up
Below is a wiring diagram on how to successfully correct the issue
My Trans is shifting correctly again
Cut the White VSS wire out of the transmission
Rejoin and solder on correct gauge wire and shrink over to ensure its sealed from weather
Run new wire up into the engine bay and feed through
ECU loom bung
Remove Glove box and you should see the wire coming out
Neatly run down into the
ECU loom plug
Cut white wire into 58 pin and safely terminate cluster feed in, ( leave enough length out of
ECU plug to solder in new feed and to later return to stock )
Rejoin and solder new feed with one end of a 1K resistor to the wire out of the
ECU loom now directly feeding pin 58 on
ECU from VSS, Shrink over to keep neat and safe
Cut Red wire feeding pin 71, Rejoin with the other side of the 1K resistor. Solder and shrink over for safety and protection
Can supply photos, but would rather do it again on my car as i can neaten things up more to help demonstrate professionalism
