1. Anyone know how tough it is to replace the clutch?
2. Do you have to drop the trannie?
3. Do you think the other Levin would be asking stupid questions like these?
As the clutch resides between the engine and the transmission, you do indeed have to separate the two. Some people do it by pulling engine. However, its usually easier to pull the transmission to get to it, as long as that is all you are planning on working on.
I've done a couple of clutch replacements on previous cars (RX-7s and the like), but I could easily bench-press the trannsmission into place, and I didn't worry about lifting the car 18-24 inches into the air on jack stands and ramps. However, I'm going to go out on a limb and bet the T56 would require a transmission jack and a two-post lift at the minimum, so it all depends on your resources.
Otherwise, its pretty straighforward...
