How to replace a clutch on a 1998 Toyota Corolla?

well, if you know for sure something is mechanically wrong, not like lack of fluid, then you want to start by taking the half-shafts out; those are the round driveshafts that have rubber boots on either end, then loosen the transmission mounts. next take off the air box and remove the battery, these are in the way for the next step- loosen off and remove all the fasteners that hold the transmission case to the engine. remove the transmission, then inspect and replace any broken, worn or old parts replace the transmission, airbox and battery. this would probably take a mechanic somewhere in the range of 5 hrs. it took me about 7 hrs with a break.
