Problem with auto converter isnt locking up

[NissanGQ4.2]

Mine looked nothing like that with the sump off....

Would be interesting to know what gearbox is in yours Marc

When you did the auto service and had the pan off did you disconnect any electrical connectors or undo any bolts with an earth connection under them?

And when you have it off again check your temp sensor wires as well, mine was broken and could be the reason it is not locking up

Didnt have to unplug any wires, had access straight to the bolts..

I'm pretty sure I have them named correctly. The white wire should be connected to the A/T Fluid Temp Sensor, mine wasn't when I took the valve body out.

Also there were about 4 different styles of A/T temp sensors fitted to the GQs so yours might look slightly different to the one in the pic. Mine was different.
Sorry I'm still having internet issues so can't post a pic of mine

ok changed the filter today although look at the old one, it didnt look clogged and could run fluid through it with no restriction. nothing on magnet since last time i had it off a fortnight ago,put pan back on and filled it up. took it fdor a test drive and still wont lock up. when i had the pan off check and double checked for any loose or disconntect wires. might try running a wire as suggested to manually engage the lock up and see how that goes.

am leaning towards the converter it self is stuffed, but the tranny guy on the 9th should be able to tell me ya or nah when he does his diagnostics.
has any one else got any other ideas?
