rear main seal must be replaced. also, is it leaking because the crankcase is holding pressure? your PCV is supposed to prevent that, to keep the seals from bolwing oil. if it got clogged, the rear main was the first to give, but wont be the last. once a seal blows ANY oil it is all done. Is PCV clogged? Are other seals leaking. Replacing seal not complex, but plenty time-consuming. The transmission is backed out or removed completely. The torque converter or clutch is disconnected from the flywheel or driveplate, and the flywheel is removed. the rear main seal is removed and new one drifted in. 3 hours in a shop. good time to replace clutch or torque converter if problems there, too.

Is there an additive to stop transmission leaks?
Depends of where the leak is. If it's a seal they have some additives that can swell up and restore an old dried out seal which "might" fix the front seals or rear seals from leaking. If it's from the transmission pan you might be able to "slightly" tighten the pan bolts and stop a leak if it's "small". Bolts are small and you don't want to overtighten and maybe bend the pan or worse break one off in the transmission. Be careful.

Do the products used to stop transmission leaks wor?
Generally, no. However. Sometimes the transmission "stop leak" products may allow you to get just a little more service out of a transmission, depending on the type of leak. Most transmission leaks are internal, and cause shifting problems, primarily slipping. When a transmission leaks internally, the hydraulic pressure is reduced and clutches do not properly engage. Stop leak formulas can reduce those problems and at least temporarily, restore most of the internal hydraulic pressure; but the transmission will not last long. In the process of reducing the leak, the internal seals are softened, causing them to wear out quickly. If your transmission is experiencing leaking to the outside through a seal, the results are less promising. External seals, those which prevent fluid from escaping to the outside of the transmission, fail quickly when you use a stop leak formula, and they do not usually result in leak reduction. External seal leaks are usually caused by a split or crack in the seal and stop leak formulas do not help with that. If the leak is caused by a loose or poorly fitting gasket, stop leak formulas do not help at all.
