While on a trip out west the seal on our transmission started to leak, at one point as much as a quart every couple of 100 miles. In Cheyenne Wyoming a transmission repair wanted $300 just to look at it. I put your Transmission Fix in and not only did the leak stop, the shifting has never been smoother. 20000 miles later and everything works great. This van has 163000 miles and the transmission works like new. I'm going to use more of your products on my F150

Thanks
