2K XJ Tranny Cooler Sending Unit Tread????
Hey Guys
I have a major predicament. I am planning on installing an auxiliury Transmiission Cooler on My 2000 XJ and in addition to that I want to add a tranny Temp Gauge. Problem being I need to determine the thread pattern ( either NPT, or METRIC ). Now here is the real KICKER. I have attempted to get in contact with several Jeep/Chrysler Dealers around the country and NO ONE has been able to come up with the answer?? Finally Don Davis here in Arlington gave me the direct number to the manufacturer in Michigan. Belive it or not after speaking with them and having them go through there archives they called me back and told me " I AM SORRY BUT WE ARE UNABLE TO GIVE YOU THE CORRECT INFORMATION YOU ARE LOOKING FOR AT THE PRESENT TIME!!!!!) So my response to them was, " So you are telling me that the manufacturer of this vehicle is unable to tell me something as simple as this"? His response was, "I UNFORTUNATELY GUESS SO".
Well to make a long story short, has anyone ever installed a tranny temp gauge into there XJ with an Aisian/ Warner-4 Automatic Transmission? and if so would you please tell me the correct fitting threads. It is a 50/50 **** shoot and being that the tranny was used in Toyotas I would Bet heavily on Metric, But I usually dont do well in the casino's or lottory's. So any assisitance in this matter would be greatly appreciated!
Best regards & Happy Holidays

One other thing, I would also appreciate it if you could tell me the location the sending unit would be mounted onto the the transmission?

 

If you can locate a sending unit to replace the drain plug you would be all set. I "think" that is 10x1.5.

 

Sending unit needs to be mounted in the fluid line that exits the tranny....that's the hot fluid. Tranny pan holds the cooled fluid. Take the temp gage sending unit to a hardware store and match the thread to fitting.

 

What he said... a third party sending unit won't go "in the transmission" but in the fluid line via a T fitting.

 

......and u can't mix/match different gauges with different sending units, use the sending unit that came/comes with the temp gauge.
