Probably not a big deal to fix yourself. The main thing to watch out for is where the shims go. When you remove the cover they will either be on the end of the shafts, or they will stick to the inside of the transmission cover. You'll have a few big ones on the end of the pedal shaft and one or maybe two smaller ones that go on the end of the gear cluster shaft. Make sure they go back in the right spot when you put it back together.
