A friend of mine has a TH350 short tail out of a early 70`s Nova, the car came with a 307 small block. When the transmission was removed it was working, it had over 70,000 miles on it at the time, if memorey serves me right it was removed sometimes in 1989 or 90, it was kept in storage and out of the weather, I said we should just check the condition of the seals, as I don`t trust seals that are 15 years old that have not been used, I`d guess they`re likely hard, he got other opinions, and they all say "run it" It would be simple to just reseal it if that`s all it needs, but he`s getting ready to run it so he wants to try it as is, Opinions please? what do yall think?

Flush it out, new filter and fluid and replace the seals.

[crazy larry]

filter, fluid and seals. good to go.

or, just run it, realize that it does leak, then pull it, and then do the seal swap.

tell your lame-o buddy to do it right.


for what it would take to do it now, as opposed to later, do it now. think he'd like that better?

Inspect it , like everyone else here said,
It is easier now , than putting it in and only get 1,000 miles out of it.

At least do the input seal because you can replace the rest without having to pull the trans out.

Speaking from experiance it SUCKS when the input seal (torque converter seal) goes out. It took me 24 QUARTS of tranny fluid to get it home At least no one tailgated me because their windshield would be coated with ATF in a hurry It didn't seem to matter what speed I was going it leaked out 3-quarts (enough to make it not go forward) in about 45min.

Going threw the very same thing myself. I pulled the trans out of a full size truck that I had driven and know the trans was good. It's been sitting now for three years....I figured, IF, there was any problems after it was in........What a PITA it would be to pull the darn thing back out to fix something I could have prevented to begin with......

A Master Rebuild kit that comes with all the seals, gaskets, bushings, thrust washers, frictions, and steels is under a hundred bucks off Ebay. Seems cheap for the piece of mind knowing I won't have to fool with the trans for years to come. Dan
