Hi.
I am planning to address the grinding I get when going into 1st gear at anything faster than a full stop. The Pelican article on the replacing first gear seems pretty good, and I plan to search these pages for nuggets of wisdom before starting. This thing has been grinding as long as I have had it and certainly long before that ... so I figure it is in pretty bad shape. Pelican suggests the following parts: slider, shift fork, synchro ring and brake band, dog teeth, and maybe first gear if it is worn. I plan to open it up before getting parts - and I assume they are all available without much trouble. I'd appreciate your thoughts on tackling this project as well as any advice. Thanks. Christian |

Christian You do know there isn’t any syncro from 2nd to first, you basically have to let the gears mesh up to shift. |

My experience, after rebuilding a couple dozen transmissions over the past couple years is it’s rarely just first gear. That gear might be giving you most of the issues but unless it’s a really low mileage trans, there’s probably more to do. You will know once you open it up.
Before you get too far into it, you can open up the side cover and inspect the ring and pinion. A damaged r&p pretty much disqualifies the trans from getting rebuilt. |
