Hi Guys. I have a Gen 6 celica with about 218k on the odo. Just today, i was leaving the driveway and the road was a bit up hill. My steering was locked right to its max (narrow street), and i was giving it some power to move forward and narrowly miss the kerb. I suddenly heard a huge bang from my engine bay and my car was just rolling backwards. I initially thought i had hit something, but it turns out that it was something mechanical inside my car. The car doesn't move in any gear...all you hear is some weird gear grinding noise which gets a higher pitch at higher gears or rpm. The car never stalls...when in gear, if i completely let go of the clutch, the gear grinding sound is only heard while motionless. Prior to this, i've had a few problems which I think may have led up to this. Just in the last 6 months, the car will ***** like crazy if cold and when the clutch is in contact. This would go away after 2 mins (when car's warmed up). Also, while driving, I remember hearing weird clattering sounds coming from the engine bay while accelerating after changing gears. The car is now sitting in a depot, waiting for transfer to a mechanic. Does anybody know what the problem is? Clutch, gearbox, drivetrain? Also, how much will I be looking at for repair? Thanks guys
