Trannsmission cooler
 

ok, i read the threads about using synth trans oil as an upgrade, if you have added decent hp/rwt to ur stang, rather it be automatic or stick. Ive talked to my friends and my people for a few weeks and what i have learned is #1. I could beef up my tranny.#2 i can upgrade my tranny cooler. i hear that will do better than just going synthetic alone.
Bottom Line, Heat Kills and warps.

You have an 08 GT with an auto right?
