I am putting a temp sensor in the trans line for the Racepak. Should I put in the top or bottom line coming out of the trans. Also what kind of temperature should I see during the run.

You can’t put it in the pan?

Better to install the temp sensor in the trans pan.

Why is it better to install in the pan? Just curious as to your reasoning.

I put mine on the pan simply because I want to know trans temp of oil going into trans and converter. That tells me how well the cooler is working.

The output line from the trans is on the bottom. That is where you will see the fluid temp as it leaves the converter. You will see the temp increase rapidly during the run. It may rise 60-70 degrees or more during the run. What is surprising is how much the temp will drop just driving the car back after the run.

Depends on what you want to watch. ^^^^^ Bob ^^^^^ is right bottom line out will show instantly what is going on with the trans. By the time it gets back into the pan it is already cooled off. During a run the temp in the pan barely moves.

So IMO if you're trying to identify a possible problem use the line out, if you're only concerned about consistency the pan would be the spot.

I am not just concerned about the fluid temp. I have always considered the expansion potentially of the converter physically due to heat. Measure your converter at room temp and then when fully hot. I Try to use the fluid temp coming out to correlate (somewhat) with the Size of the converter for consistency. Still working on it.

Place a sensor in both the pan and the line then put a switch on it? I know it can be done for digital gauges. Why not a racepak guage?


Do not argue with an idiot. They will drag you down to their level and beat you with experience.
