I'm not a transmission guy but I have an opinion..... I think the 2 choices you have are either pluming it into the output line from the transmission (into the cooler) or in the pan. Personally my suggestion is in the output line. The fluid is picked up through the filter and put into the converter where most of the heat is generated. Not sure but I think temps can reach like 300 out of the converter. It's then sent through the cooler and back into the transmission where it is routed to the valve body for distribution to the clutches, then back to the pan. So, you can put it into the pan but you are not going to read the max temp in the transmission. Also, the hot fluid coming out the transmission is mixing with cooler fluid that has been sitting in the pan. If you have a finned or deep pan your fluid in the pan is going to be cooler than that coming out of the transmission so you are not going to see a temp change as easily.
Probably true, somewhere in the middle is probably the true temp.Originally posted by PTS XTREME

You want to measure working trans temp not just fluid temp waiting in a reservoir to be used, pan temp is inconsistent and coverter out temp is not true trans temp as it is what the tc is generating not trans. we believe cooler return is the most accurate and consistent place to measure what the trans is actually running.
I aim to add comedic value wherever I go....
Certainly if you know your car you're OK. All things being equal, if your trans is heating up it'll eventually heat the fluid in the pan, it might just take a little longer and be less pronounced. Putting it in the lines it going to give you a better indication that something it up sooner I would imagine. If Eric says it's OK in the pan, who am I to argue!

Above 250 on the cooler side of the cooler would be bad...
I’ll let the experts who actually build these things tell you temperatures, I’d be interested too. I think it also depends on what you are doing with the transmission. You have it before the cooler so you are getting the supper heated fluid after it comes out of the converter, at least with a TH-400 you do. I’d think the temperatures should be the same for a TH-400 and TH-200R. I know if you have a trans brake on the car temps are going to soar very quickly when on the brake. One book I read stated that with a really high HP car a TH-400 can increase trans temps 100 degrees per second. Naturally you’re continually pulling in cooler fluid from the pan so the trans temp gauge isn’t going to go up by that much. Foot brake won’t raise it that fast I’d imagine.
