Clutch is loose and the gears are hard to shift.

Take the rear driver side tire off, u shoul see a spigut (like that on the break calipor) to use to bleed ur clutch....u need two ppl for this too... have someone pump ur clutch pedel 3times and hold it on the 3rd pump, take a 10-12mm wrench, and real quickly open and close the spout. do this a few times, if there is air in ur lines, it should "spit" at u a few times... and its a good idea to have a container of brake fluid on hand... You will need it. ( open the front trunk and take the cap of the master sillendor and check and make sure u have enough fluid..... hope it helps and hope u understand.. if not, contact me.... (i just installed a new clutch in my MR2)

When you say clucth is loose you probably mean that you have a lot of free play on the pedal..?

is it hydraulic?

if it is you'll have to bleed the clutch. if it isn't you'll have to adjust the clucth linkage.....
