Clutch Servicing

[2001GTPEWTER]

I'm not drag racer but this car has proved to me that I seem to ride heavily at some times on the clutch, and every 20,000 miles that I put on one of these cars, the clutch will warn me that its not working exactly 100%. The gears are shifting fine, of course I don't always shift the same way every time I drive, a lot of times I short shift to save both gas AND the clutch plate..The throwout bearing I'm still sure is gonna present a problem in the next 5,000 or so. But instead of paying another $800 to have another clutch put in when I need it, PLEASE help me learn how to service this tranny myself. I put the car on four blocks yesterday, I don't like the jack stands I bought, just to look at the tranny and cross member. First I think I have to disconnect the starter, and as long as Im not removing the entire tranny I can leave all hoses in tact. But once I unbolt the bell housing from the engine, how do I move the transmission back far enough to work on the clutch? Do I need to remove any part of the drivetrain or anything else? Greg
