Chris uses Lucas Transmission Fix in 1991 Chevy Suburban

I purchased my dream vehicle well used. The previous owner used it to pull a small trailer with a sports car on it; he said that after having transmission work done it never pulled the same slow shifting, if at all. I test drove the vehicle and found it to be as he said. So I bought it. Got it home drove it that way for probably a good three weeks until I got tired of it. Went to a local parts store, picked up some trans fix, removed some of the old trans fluid. Added your product, now I pull a 22 foot Crestliner (fiberglass) with a 150 horse outboard regularly, stuck and broke down vehicles (every chance I get) during the winter months. I frequent mud, fields and where ever else I need to take my pride and joy to get to favorite fishing or hunting spot, yep even off road, did I mention all of this made possible for less than $20. Oh by the way 234,000 miles now it had 160,000 when I brought her home. Been using that stabilizer since I bought my 91 pickup in 95; 180,000 miles later does not burn an ounce of oil. My mechanic has been begging to buy it, no way no how. THANKS FOR A GREAT LINE OF PRODUCTS!!!
