Review on JET 80001 Auto Transmission Module by Michael Ostler

This product failed to deliver any substantial improvement in my automotive performance.As a result of using this product I found that it only caused my vehicle to shake and stutter while trying to shift gears. The only positive note is that the installation process was relatively easy. Unfortunately, the downsides far outweigh any potential benefits. Save yourself the hassle and look elsewhere for quality ignition parts..
