With about 240,000 miles on my '96 truck, I've suffered with less than optimal performance from the transmission for awhile now. Upon the advice from an auto parts employee, I added a bottle of your transmission fix. Guess what, I was skeptical at first (probably like most people), but two weeks later and a full tank of gas later and I'M a BELIEVER! The tranny shifts smoother, there's more power on the accelerations, and...the best part of all... I've gained a full 2 MPG increase over what I was seeing just prior to using your transmission fix! Thanks a bunch!
