Thread: oil temp guage for ZF auto

Not a rangie but mine is welded into the sump. First one was next to the drain plug. New sump has it in the flat side at the front. I haven't got the box above 50 deg since the rebuilt yet. Old one wis farenheight. I bought an actaul gearbox oil temp guage.

Same. I silver soldered a brass fitting into the front of the sump next to the return line. temps get hot when towing and now gearbox is kaput...

Ok. But does anyone have any other method. I would rather not remove the crossmember again to remove the sump. I still have to run the hoses up to a custom oil cooler on the back of the ute so I was hoping to be able to get an inline sender.

silver solder a tee piece into the line and fit where you like. Preferable to use hot line.....from high side of oil pump.

Thanks. I'll do that

I guess the clue is that the standard temp switch on a RRC is in the circuit before the cooler.

IIRC somebody on this forum was using one of the TM2 temperature gauges to monitor their auto.
Its a bolt on sensor so no need to break into the oil system - just monitor the temp of the case itself.

Thanks Steve, but I would prefer to monitor the actual oil temp. The auto will be behind a 4.6 and pushing 35" tyres, mostly offroad so I reckon monitoring the oil temp ill be pretty important.
I will also be running the oil cooler at the back of the cab (ute) with a thermo fan so I will want to know if the thermo fan stps working for any reason.
