1) There seems to be some sort of locking mechanism that keep you from being able to shift into first gear when the wheels are spinning at a certain speed. But now, even when I'm stopped, the locking mechanism seems to occasionally still be engaged preventing me from shifting into first when I'm stopped. Enough coaxing and it'll go in. Any info on this lock and if it's adjustable or serviceable without dropping the trans?
2) If I'm rolling backwards slowly, even with the clutch in, when I shift into reverse it's makes a clunk and sounds like I'm grinding the gears. Does the clutch act differently for the reverse gear or is that something I need to look at?
