This happened a few months ago, my transmission would not go into gear. So i just now got around changing the clutch, throwout bearing, master and slave cylinders. I get all finished turn the car on and I still cannot get the damn thing in gear. It shifts just fine when the car is OFF or if i jack it up (being level) and turn the car on, but once it gets on the ground it will not go into any gear. Its doing the same it was doing with the bad clutch. I am baffled, I double checked everything and everything is ok. The Clutch is bled properly with no leaks. I really hope its not the transmission.
