Hey guys, what's the average tranny temp for a car with a 3500 stall and a trans cooler? Mine is sitting around 191 while driving.

I have a SY3500 converter and I average about 20 to 25 degrees cooler than my coolant temp. My coolant temp varies 180 to 200, and my tranny is around 160 to 175.
I got better tranny temps by upping my radiator in size and then moving my tranny cooler under the airbox (Used to have it on RH side by turn lamp).

I have a Y3000 coupled to 3.73's with a 24K cooler and 3qt deeper pan by B&M.
My freeway temperatures in hot summer are 135F to 150F, and stop and go around town 165F to 180F.
I live in a very warm climate.
I am running a 180F thermo with the fan on/off adjusted in the PCM. I rarley see temps over 200F, mostly 187F on freeway, 197F around town.
I am reading the trans temp from the 1/8 NPT port on the transmission housing, and using a Cyburdine digital gauge.
