What is the best temp sensor location. I have personally found that the temp coming out of the trany going to the cooler runs about 20+ deg hotter then in the pan temperature I thought it would be more important to know the hottest temp so you can at least tell if you are starting to burn your oil. any trany experts out there?

what do you think is the best way to take trany temp??


A. In the trany oil pan
B. The pressure out line going to the cooler

 

have you gotten any opinions on where to place the tranny temp sensor? where did you put yours? are you getting good gauge readings? i just got an Auto Meter tranny gauge (mech) for my '02 F150 Super Crew - I do a lot of towing and thought this would be a good precaution. Do you have any suggestions on where to place the sensor? Also, can you give me some pointers on the intallation of the sensor.


Thanks

I set mine up with the sensor spliced into the trany outline, between the trany and the trany cooler. I put mine right behind/below engine radiator I just cut the rubber hose going to the cooler installed a brass 1/2 cast "T" fitting with nipple fittings on each end plugged into the trany hose and clamped quick easy install. I found this set up gives me instant! readings on my trany temp. I was amazed at finding out what things caused your trany temp to sore!. Such as stopping after a long drive and just letting it sit at an idle with it still in drive like when your in a drive thru. NEVER! leave it in drive if you are going to sit for more then 1-2 minutes. If you run your sensor to your pan you would not notice this fact for about another 20-30 minutes when the temp of the oil is well into 240-260 range. So for that reason alone I now swear by installing the sensor on the out line of the trany it may read a little high as an average compared to the temp in the pan but I know when I am damaging my trany before someone who use pan temp does. On average the outline temp reading is close to the same as the pan temp when you are moving / towing because the fluid is moving more. I compared mine with my brothers temp in his truck (same as mine) but his sensor is in the pan we both read about the same temp at the top of a mountain pass and such.

 

thanks for the good info - as for the install - the Autometer has a pipr thread brass fiting used for threading in the sensor. How did you get aroung this with the install you described?

Thanks

A picture is worth a thousand words. I posted a pic of my set up (see link below) You will see the bottom were the sensor screws in. My meter was an Autometer also I think it came with with a 1/2 nut fitting? I used a 1/2 to 3/4 adaptor so it would screw into the "T" fitting. I used a 3/4 "T" because thats all they had at the time but it worked perfect because it accomidated for the length of the sensor (it might of been 3/8 to 1/2, I cant remember which) you should be able to get this stuff at any good hardware store or pipe fitting store. Just make sure you use a pipe dope on the threads and screw in the nipples and adaptor in tight so you dont get any leaks
