Ken Majchrzak uses Lucas Transmission Fix in 1993 Dodge Dynasty and 1990 Pontiac Bonneville

My wife's 1993 Dodge Dynasty had 95,000 miles on it and the transmission began to shift and downshift hard. I had the transmission and filter changed with back-flush treatment for $180 at a local Precision Tune shop. The fluid really did need changing. However, this did not fix the hard shift problem, in fact the car got stuck in first gear for a short time immediately following the flush. The shop manager/owner told me the transnission was "on it's way out" and to take it to an AAMCO transmission shop for an estimate.

The following testomonial is no BS - I bought a $10 bottle of Lucas Transmision Fix and added it to the 1993 Dynasty. Not only did it fix the hard shift problem within two days of driving, the car (temp guage) actually ran cooler also! It continues to shift quietly and smoothly for over 4-months since adding the Lucas transmission treatment without any trouble. The car has over 100K miles on it now.

Because I was so impressed, I added a bottle of Lucas Transmission Fix to my 1990 Bonnevile that had 190K miles on it. This car was shifting OK to begin with, but it shifted even more smoothly and ran cooler after I added the Lucas product. My Bonneville now has 200K miles and you cannot even feel the shifts from 3rd gear to O-drive. I am now a true believer - THIS LUCAS TRANSMISSION FIX PRODUCT REALLY WORKS!

I now plan to try Lucas Oil Stabilizer as well as the Upper Cylinder Lubricant with Injector Cleaner.
