B Haufe uses Lucas Transmission Fix for 1989 Acura Legend

I am so excited, that I just had to write you at once. I just returned from a mobile quick lube place, for an oil and transmission fluid change.

I drive a 1989 Acura Legend. When I bought it, it had about 90,000 miles on it. I was pleased with it, except it would shift rough. I took it to a Honda dealership, and was told it probably needed "Acura transmission fluid". Since it can't be replaced all at once, we did three separate changes, at $29.00 a piece. The problem improved slightly and I let it go for about one year. Then I took it to a reputable transmission shop, prepared to have to rebuild the transmission. I was told my transmission was OK and that this model car normally shifts rough. They suggested trying a fluid change and an additive that might improve it slightly. I tried without great success.

Resolved to the fact I probably would have to drive the car as it was, I let it go until today. Sick of the rough shifting, especially into second and third gear, also it now had started to "shutter" when shifting gears. I went to Discount Auto Parts. The salesman recommended your product. I asked to have your products added to the engine and the transmission. After driving out of their driveway, I already noticed a difference. Two miles down the road I had about 20% of the rough shifting into second gear, and 10% into third.

I feel like I have a new car and can't wait to see if the engine knocking goes away (it only does it when cold).

Thank you.
