Review on JET 80421 Auto Transmission Module by Tyler Parker

Revainrating 5 out of 5

Excellent 04 f150 4.6

Easy install, about 10 minutes. This element takes 4.6 in 04 f150 to the next level. Throttle response is great and you can feel the power. He recommended 91 pump gas for best performance and 93 for towing. I ran 87 on the first test.
