An additive for your automatic transmission fluid that stops small leaks. Lucas Oil has one such product in their product line up. Need to stop spots on the garage floor.

Great products. I was at the Memphis dragsd last year with pit passes. Watched Dean Scuza;s team rebuild a blower. After they were done, they cut the tops off 2 bottles of Lucas oil addative and dumped both in the blower! ;) Sold me.
