TB42 Auto box Electricals?

[WADS]

Hi Mate, I have had an experience with a GQ diesel auto that had an auto failure and wad rebuilt. after which the transmission would drop out of lockup. After much testing it was found that the engine wad running too cool. The lock up in this transmission is sensitive to the temperature of the transmission oil. Ensure that the return oil line to the transmissoin is connected to the drivers side of the radiator and not bypassed by having an external oil cooler fitted.
We found the engine cooling system thermostat to be the cause of this.
Hope this helps.

Any updates? Did the new valve body fix it?

Ripper, update to his auto transmission drama's can be found in his members ride thread: http://www.nissanpatrol.com.au/forum...ucas-s-TB42-Ti

The valve body wasn't the problem they just upgraded it while the gearbox was apart, and no they haven't fixed it yet problem is still there

Cheers

Thanks Todd.
After months of frustration with our auto, I recently found the problem, a broken wire that was intermittently playing up, so I can sympathise, and may be able to help here.

I don't have much time today, but I'll make myself known in the other thread, and see if I can think of any new possibilities.

Cheers for that Todd.
I'd be interested in the broken wire info ripper. I've answered you in the other thread. If you've got any ideas it would be good to hear them in my members ride thread. Thanks in advance

tappn it

Was the wire that was broken inside the valve body??? when my gearbox sh!t itself I found a broken wire inside the valve body which I believe was the temperature sender

I'd be interested in the broken wire info ripper.

I've written up the story at the end of my old thread here, but I'm happy to give more details if you want them.
Anyone rewired a rev sensor in a GQ automatic?

Was the wire that was broken inside the valve body???

It went to a solenoid on the valve body. The break was either inside the box, or outside within about 100mm of the case.

Edit:
I'll keep future comments for the other threads, it'll make the info easier to understand.
