Dear Marston:

If you are going to do the work yourself I would try replacing the pan gasket first. The fluid level when parked is higher than the gasket.

For a sealer I recommend Mopar ATF RTV which is very good. Make sure the pan is not distorted and if so true up the surfaces. The original gasket was paper but today imitation cork is being sold, so I wouldn't over tighten the bolts. Tighten enough to compress the cork and let the sealer act as a threadlocker.

Finally, let the thing sit empty for at least 24 hours for the sealer to cure.

If the unit is a good performer I wouldn't change to a 727 Torqueflite, but if the trans is a clinker then the cost of switching to the 727 is about the same and worthwhile. The 727 will outperform a stick shift.

Hope this helps
