Yes on what Chuck said. That is the common failure of the earlier non-syncro
first gear transmissions. Especially for racing, the later case is a must
have. But you would still have the o.d. issues.

p.s. if you have leaks, as a last resort, try to catch them with absorbent
material and not drip freely to the pavement and race track.
