Good morning all! I’m going to spark a question this morning about the best place to install a transmission temperature sensor. With today’s aftermarket you can pretty much put them anywhere, pan, trans cooler out port, trans cooler in port, line pressure test port, in the cooler and more. Please refrain from: This is the only way to do it, stock is… and I’ve always.
This is a question of where you think the optimal location is it and WHY, it is a discussion and not an argument. I really look forward to all of the insight from the gurus out there! ![]() |

Re: Best Trans Temp Sensor Location, What’s Your Two Cents?
I put mine in the line going to the trans cooler. Figured that would be the hottest temp readings and give me an idea of what's going on in the trans.

I have the ECU in the 71 reading mine. Which is inside the tans. Not sure where it's mounted but think it's in the pan area.
On my 64 SS Impala I installed it in the pan drain hole of the power glide.I have to take it out any way to drain the fluid so I just used it to plug it up. Chevy puts their's in the pan that's good enough for me I don't race them so it's a general reading anyway. ![]()

Re: Best Trans Temp Sensor Location, What’s Your Two Cents?
So, do you guys think it is better to know the temperature of the fluid in the pan or the peak temp coming out of the transmission? ?? ???

![]() The return line supplies the fluid back to the transmission and to the pan. The fluid is in the pan to be pumped back through to the transmission so if the fluid in the pan is the cooliest spot then I think it's the best place to read temp for it. ![]() Quote:

Re: Best Trans Temp Sensor Location, What’s Your Two Cents?
The factory puts the temp sender in the pan. Hopefully their engineers know best.
It would be nice to know the temp of the outlet of the cooler. That fluid is going back to the trans to lubricate the gearset before it falls in the pan.

Re: Best Trans Temp Sensor Location, What’s Your Two Cents?
Put mine in the return from the cooler along with a filter. I wanted to know what the temperature of the returning fluid was. This was on my GTO which was my daily driver/ Bracket race car. The theory was I could see how well temperature from being hard up on the convertor was being controlled. It didn't take long after I installed it to change how I used the convertor and how I did my burnouts in the water box.

Re: Best Trans Temp Sensor Location, What’s Your Two Cents?
Cooler return is also the lubrication circuit. The fluid doesn't go from the cooler to the pan.
