Best place to mount ATF temp sensor
I ordered the short sweep 2 1/16th trans temp guage from auto meter, i think i know where im gonna mount the sensor but ima wait to do it till im do in 400 miles or so. Im thinkin the drivers side of the pan, two pan bolt holes from the tail housing, pointed in from the side of the car. keep in mind i made this judgement call lookin at the old tranny on the floor of my garage, not the one in the car.
Whos got it and where did you mount it?

I put all mine in the trans line to the cooler. IMO you want to read the highest readable temp. When you see the charts that tell you whats going on with the ATF at a certian temp and how long it's going to last at that temp, I see no point in reading the average pan temp.
In the cooler line you read the average highest temp IMO that gives you a better idea of what the internal temps are that you can't read.

I did some experimenting with this subject in in a pickup with a 700R4. I tried the cooler feed line and three locations in the pan, all with the same Dakota Digital 2-1/16" gauge. The temp at the front of the pan (closest to the torque converter) was highest by as much as 10 degrees.
After choosing that location permanently for my sender, I added a big B&M cooler and a deep TCI aluminum pan. I found the major benefit of those mods to be as follows. By increasing the amount of trans fluid (with the cooler & deep pan), it took quite a bit longer for the temperature to change. When towing on a grade it took much longer to get the the trans HOT. But due to having more fluid, it also took quite a bit longer to cool the fluid down. Such as going down the other side of the mountain and staying off the gas.
I've always suspected that in something as light as a passenger car, simply increasing the fluid capacity does more to curb transmission overheating. Unless your going to bury the speedometer for 20 minutes...

i buried it for 15 one time so 20 damn sure aint out of reach.
lol, 40 min trip in 15. never again though, not that stupid nowadays. im just lookin for the sensor to be where the fluid is highest. The PCM will throw a code if it gets too hot but ive got a TC and a brand new trans and wanna go to the track without toasting it all. Ill put it in the pan for now and maybe experiment with it later. Thanks guys youve been a big help.

well ok. I was going to put the sensor in the pan and change the gasket and filter at the same time but that turned into a total train wreck and the sensor was left out. next we try the output line of the tranny.
so witch line is the output and which is input?

pressure port worked perfect. threaded in with no adapter, wire clear of anything harmful, even close to an existing hole in the floor pan.
Thanks fellas, helpful as always
