After towing out 5000 pound trailer back and forth to florida with our 6 cylinder Trailblazer with the 4L60e transmission a couple times, we found that our 2-3 shift was slipping badly and he transmission fluid was turning brown (in only 1700 miles)......we installed the JET Shift Improver Kit and we now have very firm 1-2 and 2-3 shifts with no slippage......this an excellent product and would highly recommend it to anyone with the newer electronic transmission....we had excellent service with fast delivery, and the installation was simple.....I only wish I had had we had installed this unit when the vehicle was new.....Bill Hewitt & Bettina Laier

The product seems to work very well and is a good edition to any automatic transmission that has a higher performance demand. The only set back was the instructions. They didn't go into much detail. Other than that I would say it's a great product.
