Hi all,
First post here, would like some help with a few fault codes which I think are related.
I DIY'd a test light and worked out how to read the fault codes on my EF Falcon.

Code 634 and 636 seem related by the same fault but I dont know where to find the wires.

636 is Trans Oil Temp Fault and 634 is Gear Selector Sensor Faulty.

Reading a technical bulletin I found it says the ground on the temp sensor is the needed for the gear selector. So I think the ground wire has a fault.

Where is the Automatic Transmission temp sensor and where does the wiring loom go? I can do some continuity testing with my multimeter maybe.

FYI: all fault codes are:

786,786
10 - break in codes to signify different codes are coming
452
578
634
636


Cheers!
