i just replaced my tranny i swaped housing because my old one had a hole so i swapped the gears into the new housing while i did that i replaced the clutch and flywheel but now for some reason its stuck in gear when i start it but when its off i can shift freely but still in gear when i start, and when i let off the clutch there is a loud knocking sound comming from the tranny. could this be a isb related problem?
