Their are a lot of companys out their that make tranny coolers. Which one do you guys have in your 3rd gen's and what size did you buy? What comany has the best one, or does it make a diffrence?

 

i would like to know too, and I would like to know how and where to mount a tranny temp guage?

 

When I installed a tranny temp guage I did it when I change the tranny fluid so I had the pan off. I bought a temp guage and senser at carquest. I drilled hole in the pan and installed the senser which came with a brass fitting but i bought a steel fitting so it could braze it to the pan and installed the guage under the dash. I put in a tranny cooler shorter after. A believe it was a medium sized cooler but it probably wouldnt hurt to get a smaller since im not pulling anything. I also installed the cooler before the radiator so the tranny fluid would have a chance to warm up.
