Torque converter seal question
Posted by: thumper477 ()

I am replacing the torque converter on my 1965 Monza.The ring gear is bad causing starter problems.I have heard here of problems with new torque converter seals leaking.What is the best seal to use for this? I only want to do this job once.I am putting in a remanufactured converter with a new bushing.

National seal #9845 according to a post Steve G made on the forum. Some time back!

Hope this helps!


I believe it has two lips on the inside to get better sealing.

That was the one I used when I replaced mine!

Hope this helps!

Thanks.I looked it up on autozone and it shows 2 lips.They have it in stock.Apparantly it fits modern cars for timing covers and main seals.

Mike Dawson in KC gets credit for finding the seal, I just pass the number along and of course use it in customer cars.

best wishes, Steve

The seal I used from Clarks leaked not from the lips but from the outer seal to case. I used a thin coating of grey rtv around the outer perimeter of the seal the second time and no more problems. I also recommend a new converter bushing to hold everything tight.

The spring loaded lip is the oil seal. The second lip is to keep dirt off the main lip. Always install seal with spring lip toward the liquid or grease.
