I was currently using a flex-a-lite cooler (about 7"x4" in size) and with my mods (read sig) the trans temp was always around 215-225 degrees . Today, I picked up the B&M supercooler (The biggest one) PArt # I think is 70566. This thing is huge compared to my old one. I hope now I can get my temps down to 200 or less.

 

hell they need to be around 190...i know with a bigger stall it heats it up more. i'm getting a temp gauge and bigger tranny pan to make sure i don't *** my tranny for a third time.

 

i have yet to see above 180 in mine with a B&M 19000

 

I already have the 3QT aluminum deep pan with fins from B&M, and now with this huge cooler, I should be under 200 degrees. I think the hardest thing about keeping our tranys cool (assuming you using a cooler) Is that no matter where we mount the cooler, its next to impossible to get air to travel "OVER" the entire cooler. The is almost no room to mount these things.

 

Mount the cooler on the condenser where it will have air drawn over it from the fans. There is plenty of room.

I tried mounting my cooler under the air dam but my fluid got way too hot. I had to re-mount it where the fans draw air across it before the cooler lowered the temperature any significant amount. My tranny never gets over 180 degrees now in 90 degree temps. It may be too cool this winter though.

 

Yep, never higher than 175 with my B&M 24k

 

I belive I have a 24K cooler, And someone mentioned to mount it on the condenser, well I dont have any of the A/C system anymore, so It tried to the radiator, separated with rubber feet.
