TH 350 Leak ?

When I bought my 71 GMC it had sat for years, the transmission has a leak and was wondering if any of the stop leak products on the market are worth trying to stop it ? Should I just plan on pulling it to replace a seal ?

Replace the seals. It sucks to do but don't trust gunk all I. Your tranny

I wouldn't bother with stop-leak products. They might buy you a little time, but if seals or gaskets have gone bad, they should be replaced..... even though it takes more effort & money.
