Purchased car 2 years ago with 65,000 around 70,000 it started shifting extremely hard into 1st when slowing down and had hard launches from the start. In the winter you had to let the car warm up 15 minutes or when it shifted into 2nd it would slip. The tranny shop said I needed to have the tranny rebuilt. I figured I wouold just drive it until it left me stranded and then have a complete rebuild. Fast forward to now the car has 107,000. I was in buying air filter for the car and over heard the sales man tell another guy to try your tranny fix oil. So I thought what the heck $10 vesres $1200. I poured it in drove around for about 2 miles then started to stop and go and noticed that the shifting was getting smoother. Now a week later you cant even feel the tranny shifting at all its so smooth. I will be having the tranny flushed and will add another bottle. I am sold on your products. Thanks for saving me over $1100. Aaron
