Jeep WJ transmission fluid temperature

My transmission fluid temperature is at 225°. I switched out the filters with brand-new Mopar ones and brand-new ATF 4 fluid. Along with all sensors and solenoid. Any idea why the temperature would be so high?

Also i put 10 quarts of ATF4 and when i check the dip stick its on the 2nd hole of cold. I am afraid to add more as they state for a filter change it should be 6.5 quarts.

Are you checking it while the transmission is hot or cold? Drive it around and let the fluid come to temp then check it. Should be somewhere between the 2 hot markers. Not too sure on what the actual temperature should be though.

I would still check it when the fluid is at operating temperature. Do you have a transmission temperature gauge?

I checked it right now and its right were it should be at operating temperature. I am using the super chip tuner to see the transmission temp. Everything works fine. Shifts great. Just that temperature problem, which i do not know if its normal.

The transmission fluid cooler is in a portion of the engine coolant radiator. It seems to me that the ATF temp would be close to or a little higher than the engine coolant temp. That 225 is probably normal.

Alright. Since all I seen was that higher than 200° is bad for the transmission I was worried and thought something was wrong.

That is about the temp that I would have expected. I have been threatening to install a trans temp gauge in my PML pan and your thread has inspired me to look into it more.

I wouldn't mind learning more about your tranny temp gauge set up?

This is what I am going to use for my install:
Autometer 2640 Electronic trans temp gauge
http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER


I am going to use this mount and put it in the cubby hole in the dash below the heater/ac controls
http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER


I am going to use these to angle it so it is easier to see from the driver's seat
http://www.amazon.com/gp/product/B00...=ATVPDKIKX0DER



Here is the PML pan that is tapped for the gauge.

I was having high temps on mine when I would pull my boat (yes i turned o/d off) so I installed a trans cooler with a fan and now my temp never gets over 180.

Here is the Hayden fan setup


I am pulling a 19.5ft boat with no issues now!

What do you have for a temp gauge set-up. Ryan?
