here's my question, i just picked up a hayden trans cooler from the swap meet. installed in about 40 minutes, while i was at it i picked up a sunpro trans temp guage. here's my question should i put the sensor before or after the trans cooler? i have it before the trans cooler now, so as the guage reads it's at it's highest temperature. what do you think?

2 things. I know you didn't really specify either way, but it's a common mistake. From transmissionhead.com:
"Transmission Cooling: You must have a transmission cooler in your radiator regardless of what someone has told you for the transmission to last. Auxiliary coolers are just that, in addition to. Water cools 32 times better (faster) than air always, period. The transmission fluid comes directly from the torque converter at a much higher temperature than the water in your radiator and is cooled to the water temperature fast. Then it goes to the auxiliary cooler to be cooled far below the water temperature. If you wanted to cool a red hot piece of steel fast would you stick it in water or air, see the point. For the best cooling you need both water and air cooling for the transmission to be cooler than the motor."


From the instructions that came with my B&M gauge:
"Step 2. Locate the Oil return line in to the transmission ... Note: This location is recommended to monitor the true transmission temperature going in, as well as checking the oil cooler efficiency."

That said, I installed the sensor in the drain plug in the pan.
