I have a 4-speed in my Nova that seems to have a few leak's in it. Rear seal and from the side cover , I think? has anyone else had these problem's? , and is it a big deal to fix , without taking it out of the car? I would appreciate any help.

Jim,

The rear seal isn't much of a problem. Pull the driveshaft, pry out the old seal, and tap a new one in. To put on a side cover gasket, you would have to remove the shifter linkage. That's easy, but I don't know if you have room in a Nova to get at all the bolts. If you can get a socket or a box end wrench on them, and there's room to pull the side cover, then it's not a big deal. When you put it back together, you have to make sure the shifter forks fit back in the sliders.

If you don't have enough room, you can put a jack under the tailshaft, remove the trans crossmember, and probably drop it low enough to work on without removing it.

Take a look at this page. There are parts photos, and an exploded diagram near the bottom.
