What are some good stop-leak solutions for a transmission?

Transmission sealers can restore worn-out seals and gaskets and are an effective solution for most minor leaks. Low dipstick readings or fluid leaking onto the transmission housing or pooling below the vehicle often indicate a leak. Unaddressed leaks can lead to serious mechanical problems.

A high-quality brand of transmission stop-leak that is appropriate for the make and model of the vehicle offers an effective way to address minor leaks. Sealers should be poured down the dipstick opening until fluid levels have been restored. Stop-leak products and sealers are less effective for major leaks, and mechanical repair services may be required to address the problem.
