Transmission Stop Slip with Leak Repair

Slip No More: Rislone Transmission Stop Slip with Leak Repair
You know how our bodies can’t function correctly without the proper amount of fluids? Well, the same is true for your car. Automatic transmissions don’t work without fluid, nor do they work well without the correct fluid. And did we mention these fluids are one of the most complex lubricants in your car’s system?

This product contains a special blend of viscosity improvers, anti-wear friction modifiers and extreme pressure performance additives to solve most transmission problems. These additives reduce rough…
