I just installed my tranny temp gauge today, and I wanted to know what everyone elses AT's run at.
AWWWW man, I just put a stall converter in mine and it has an instruction sheet /forums/images/graemlins/rolleyes.gif that notes the ideal running temp. for a tranny. Think I can remember what it was? Of course not. Ill take a look tommororw when I get to the shop.
I mjust put a new gauge in mine too.
The optimum temp is 150-160, if you can keep it in that range your transmission will live a long and happy life.
I've got a B&M gauge and the sending unit is installed in the pan's drain plug; which comes out the side of the pan. That's the only place to get a truly accurate temp.
Yes, I've gotta make a nice skid plate to cover the entire area below the pan very soon.
Mine stays around 150 or a little above pretty consistently. A couple of times it's bumped 180 when going up a hill on the interstate because the torque converter unlocks, but then it goes back down. I take it easy when I see it climbing much past 160 or so.
Most all trans fluid manufactures recomend a fluid temp between 150 and 165 degrees with 160-165 being the optimimum temp.Constant Fluid temps of 180 degrees can degrade the fluid by as much as 50 % shorting the fluids life drasticly.
Wore out fluid = wore out tranny /forums/images/graemlins/frown.gif
