My Mechanic has run all diags and found no fault with my CVT or fluid but as mentioned in a few posts I may have an issue with one of the speed sensors however he's reluctant to touch it without a wiring diagram.

Was wondering has anyone had luck finding a wiring diagram for the CVT G35, ie 350GT-8 2002 ?

Any assistance greatly appreciated

That's going to be tough since the CVT was only available in a few markets, I suspect it uses the same wiring and similar valve body as the RE5R05A though, or a VERY similar version.

I would start by unplugging the transmission harness (battery disconnected first) take a picture and compare to the RE5 harness to see if the wiring looks the same.

I'm not aware of any Skyline V35 service manuals available online.

You could also look up wiring diagrams specifically for the Jatco JR006E which was the CVT transmission.
