TD 4.2 automatic gearbox problem

If you're only getting 5V at the transmission, then yeah, I'd be checking why it's so low.

Thanks boss - as said, need to confirm, but this was the number rattled off to me... fingers crossed ... then I know it's electrical ... so long as its not the TCU itself!!!! lol

If you have a manual lock-up switch in it (as I thought you said here) this rules out the TCU as being the problem.

As I'm sure it was 'measured' with the lockup switch selected

I wrecked that part of my TCU by feeding 12V into it instead of to the TC solenoid, but the manual switch still makes my TC lock no worries.

Lol - yep, I have a lockup switch mate ... I know it overrides the system as such and if it works it proves the science as it were that the TCU and TC are in fact working etc - was just being a goose!! Mum told me to do what I'm good at in life, and being a clown is about the strength of it!!! lmao

I will suss out that voltage this weekend myself me thinks ... got me interested now ...

Sounds good.

Guys please somebody tell me which wires need to be disconnected when changing to manual
Box fit awesome just need to know which wires go where
Thanks

Near the battery, just under the edge of the air cleaner there are a heap of connectors, I'd start there. They're really annoying to get at in mine because of the LPG conversion. I think they often just get cut off because they're hard to get at, but they need to be unplugged if anyone wants to use the box again.

There are other wires like the throttle position sensor, the full throttle switch, and the TCU, but I think the main ones to remove are the ones into the transmission itself (including it's rev sensor).

On the subject of removing wiring, do you want to sell your TCU?

But if u really need it I'm happy to sell it to u
