I was driving normal in 5th gear low Rpms and my tranny popped out of 5th making a grinding noise. I tried to put back in 5th and nothing was there. Just sounds like a bunch of grinding noise in the tranny. I have 1st threw 4th but the rest will go into gear but nothing. I have a mgw orange shifter. Even at idle I can here the grinding noise coming from tranny I push the clutch in and it stops. Does this sound like a fork or more internal. If it matters this is a stock tranny other then the orange mgw. Help please?
