VSS Bypass* Corrected Trans Schedule* Success *

[NCII40]

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
