So i have no idea where to start, my car was running find then one day decided not to shift into gear during start up. After a few pumps of the clutch went into gear and drove fine with no slippage or grinding. But now its having the same issue during startup every time and once again runs fine once it actually starts driving. The clutch also started engaging higher during all of this. Clutch is an aftermarket stage 3 done by previous owner
