I've recently got an MR2. It will move a few foot in 1st gear when started from cold, but there is suddenly a loud jarring noise and you get no more drive. The noise sounds a bit like when you use an air gun to tighten something and when it's at the correct torque it'll click.

So basically, when I let the clutch out, it'll do that and not move. It does the same in 2nd gear. I can slip the clutch loads and it'll move little before doing it. If it's in reverse, it goes fine, no problems at all.

I've bought a new box to fit, just wondering if anyone has come across this before and if so, what was the cause?
