Works perfectly
Worked like a charmed...no more transmission leak on my 2003 Lincoln Towncar. The only issue I had was the fact that it was very hard to put on but that's cause I didn't have the right tool.

These seals (National) are a good investment.
National seals are a favorite brand of mine. They are sized properly, the quality still seems to be there. I put grease on the spring before I use a mallet to install these seals, so the spring won’t be jarred out.
