Trans pan gasket

728 6
I had a new trans installed and Im leaking a bit of ATF from the front of the pan. I have a feeling the gasket could be bad. The trans has a mag-hytec double deep pan on it. Do you think I should get a mag-hytec gasket or just a normal napa trans gasket? Mags gasket is $9 dollars, OEM is $13.50, and a napa gasket is $2.50. Whats the difference with these gaskets?

Plus napa has two different sizes if I went with them: 15" L x 11.5" W x .09" H or 14" L x 11.5" W x .067" H

I have no clue which to buy now.

from my experiences the cork gaskets work the best, so make sure it isnt a rubber gasket where ever you get it. Not sure on the size, i thought all 47re's were the same.

NAPA don't know which so offer the 727 and 904 gskts without comment. You want the larger. However I recomend the reuseable gasket from Dodge. Will fit with ease especially if your pan has a solid/flat sealing surface. It is much more expensive and gives lots of bragging rights.

If you don't want bragging rights then install the first you come across and torque properly. All will be golden and you still brag.
