Review on JET 80401 Auto Transmission Module by Chris Marable

After trying out what seemed like countless different automotive ignition parts to improve the performance of my car`s transmission, I was starting to get pretty discouraged .But finally I hit the jackpot with this module from JET 80401. It's amazing how much smoother and more responsive the SHIFTING is now, and I'm confident I won't have to worry about any transmission issues in the future. The only downside was a slightly higher price point than some other options..
