You can get a Chilton's manual for the Ford Tempo, or, in your case, whatever you got for an engine (if it is a stroked & bored 289, or whatever). Find the bolts that will enable you to separate the transmission/axle housing from the motor; go online and find a step-by-step for the same, or, get a mechanic friend to help you. Replace the pressure plate, clutch disc, and release bearing (throwout). Put it all back together w/ new gaskets, fill with the specified amount and 'weight' of gear oil, and you will spend far less in parts & labor.
Unfortunately most modern cars are front wheel drive so step 1 to separating the engine from transmission is to remove the car from it. And thats just about how it says it, you unbolt the engine/transmission subframe from the car body and then lift the car body up off of it.
