Thanks for the feedback so far. Although the later tranny swap out is appealing from a reliability standpoint, I am going to keep the 4+3 in the car. I like the reaction of people who look at my car, and ask "what is that?". And it was funny the day I went into Pep Boys looking for a transmission filter, and the "expert" manager told me there were no 84 Corvettes with manual transmissions. I asked him to come outside and look at it, which he did, then proceeded to tell me it was not original. I then took the window sticker out of the glove compartment, and then he finally believed me. The 4+3 and the Crossfire are both good conversation starters....
The 2nd owner of my Vette did not do much maintenance unfortunately. When I bought it 9 years ago, it leaked coolant, and it took me 3 quarts of oil to get 500 miles (it leaked really bad). I knew he did not change the tranny fluid(s) in the 4+3. I knew all of this when I bought the car, but I got it cheap with the intention of working on it and restoring it back to its former glory. I rebuilt the engine, did most of the suspension, brakes, exhaust, etc....so now on to the Tranny.
I have heard good things about SK Speed so far. I know the direct drive T10 is bullet proof, but I am having both the T10 and the OD re-done. I have put the best of everything into the car so far, so I am not going to stop now. The gear oil and the Dexron mixed in the T10, and I think one of the teeth are broken, so for piece of mind, I'm doing the whole thing.

)...they are decent units as long as they are properly serviced, which is the main reason they fail...folks never service them, and/or they ignore the leaks until it's too late.
