Coool

it does the job keeping trans cooler and an easy install in minutes. you gotta get one of these.

Noticeable Difference

Install took perhaps 15 minutes and was done in conjunction with the deeper pan. Prior to installation, my transmission temperature averaged 167F and now it’s 24-30 degrees cooler. Ambient temperature was 95F and after a hour of highway driving, the highest temperature registered was 143F. Very satisfied with my purchase and decision to swap out the factory’s restrictive valve.
