Leaking tranny 84 Old Cutlass

Just got an 84 Olds Cutlass Supreme
sat for 13 years, 89560 actual miles
3.8 v-6, appears front seal in tranny is leaking
someone said to put one oz of brake fluid and then two bottles of Lucas Oil tranny stop leak and drive it and see it that works
Said if it didn't I would have to pull tranny anyway and replace seals
Opinions much appreciated

Brake fluid and trans stop leak are used car lot fixes, and are ticking time bombs.
Where will you be with that false sense of security when that trans just up and quits?
Take it out... fix it right..enjoy. Its That simple.
The brake fluid will swell the seals, "helping" them to ply easier ans seal. Untill it gets so soft it blows out. AND it affects EVERY SEAL, not just of the one being a problem. Meaning that clutch pack seals, which are under way more pressure than the front seal will likely blow out before the front seal, giving no indication of impending failure.
Lucas is OK, but is still a patch, or car lot fix for a bigger problem. It also strains the pump, especially when cold, but is still better than brake fluid.
If the car isnt much , just put in a seal. If the car is decent , and has a lot of miles avoid trouble, put in a reman trans.

Sounds like a nice car. Well worth repairing correctly. A good repair should last ten years easy. Peace of mind is priceless.
