Saginaw 3 speed problem
Installed rebuilt Saginaw 3 speed. Trans will not down shift from second to first while moving. Trying to downshift to first results in grinding noise. However, if car is at a dead stop, with engine running, if I shift into reverse and then into first gear it engages easily with no grinding. If I shut the engine off it will shift easily into first.
Any ideas ? |

It is a non synchronized first gear trans. Or the first gear sychro is messed up.

This. Pretty sure that the pre 70' transmissions were not fully synchronized.

If you recently changed the clutch and pressure plate, did you wipe the pressure plate down with thinner to get the oil off it?
I agree with the above, I'd look at the clutch first.. |
