Hello! My sons and I are the new owner of a 1972 FJ40. It is a 3 speed manual transmission. We believe it is original. The problem we are having is it wont shift back into 1st gear unless the vehicle is stopped or nearly stopped. We have made sure the reservoir is filled and we have bled the master cylinder to remove any air. Doing this improved the performance of shifting but did not fix the shifting back into 1st issue. Any recommendations on how to solve would be appreciated.
