Its anybody's guess as to whether or not the leak will go away if you change back to regular fluid - ***its worth a try***, but if I were betting, I'd say that once it starts leaking, it will continue to leak (just a guess). I would be interested in hearing your results.

You should be able to tell the difference between the tranny fluid synthetic, and the engine oil. Figure out which one is leaking by *carefully* examining the fluid. The engine rear main seal is notorious for leaking on our cars, and it might be leaking, by coincidence.

The front of the tranny has a seal on the input shaft. Its a $15-20 seal, and its easy to change, ONCE you get the tranny out. Getting the tranny out is the pain in the butt part, but not as hard as you might think. You have to remove the exhaust, disconnect the driveshaft, disconnect the shift linkage, remove the bolts that connect the tranny to the engine (at least one is tough to get to, so you need an inexpensive crowsfoot wrench to loosen/tighten it). Then lower the tranny, done easiest with a tranny jack. This job can be done by an ambitious DIY'er with a decent repair manual as reference. Its tedious, but doesn't require a whole lot of specialized skill.

An experienced shop with a lift and great tools should be able to do the job in 3-4 hours (maybe faster, but I don't want to sent the wrong expectation). A DIY with mediocre tools can do it in 4-6 hours, probably 8 first time out.

Let us know how it works out.
