My 95 (2nd gen) began leaking tranny fluid at about 95K. It leaked especially when it was warm. I had never changed the fluid prior to this time. I began adding ATF+3 on a regular basis, and tried stop leak. The stop leak did not work for me. Finally, at 129,000 miles, I had a complete seal job done, which cost about $1,000, including a front transmission mount. I got another 40,000 miles out of it, which works out to 2.5 cents per mile. For another $300 I could have had a complete overhaul, and looking back, I wish I had. It would have saved me money, as I had to replace it due to a bad torque converter.
My point is if you find you have to have the transmission re-sealed, and they offer to overhaul for a few hundred more, go for it if you want to hold on to the vehicle. It could save you money.
