Transmission and Differential Stop Leak (TDSL)

Seals, gaskets and o-rings can deteriorate over time, especially when exposed to wide temperature variations, dust, dirt and water ingress. Failure to fix leaks can lead to part failure and expensive repair bills. Nulon Transmission & Differential Stop Leak is a uniquely formulated product which works fast by rejuvenating seals, gaskets and o-ring elasticity to stop leaks and fluid seepage.
