JLM Automatic Transmission Fluid ATF Stop leak & conditioner

JLM’s Automatic Transmission Stop Leak & Conditioner is designed to prevent slipping, leaks, and wear to provide smooth, quiet operation while conditioning seals to extend the life of the transmission. 

Automatic transmission fluid (ATF) serves a few vital roles. It acts as a hydraulic fluid to enable shifting, protects gears and bearings against wear, manages heat and provides frictional properties to ensure smooth, consistent shifts. Over time, the fluid deteriorates, especially if the transmission gets extremely hot from towing or hauling.

Heat causes transmission fluid to oxidize or break down. Fluids that break down allow sludge to form, which plugs narrow passages and interferes with shifting. Worn fluid can also fail to provide the correct frictional properties for your transmission. Eventually, you notice your vehicle shifting hard or erratically. Over time, the seals can also harden, causing them to crack and leak.

JLM’s transmission fluid additive is designed to restore the fluid’s properties responsible for providing the correct frictional properties, heat resistance and other benefits. In addition, it is also designed to soften and swell worn seals, purportedly “fixing” leaks.
