sometimes mine wont go into reverse no matter how hard i push on the stick. i have to do one of two things, 1.let the clutch out a little bit while applying a little pressure to the stick and it slides right in or 2. take foot off the brake and let the car roll forward or backwards a couple inches and itll go in.

am I missing something here???? As far as I know, every car or truck that I have driven in the past 25 years, including brand new cars while I worked at car dealerships, there is not one car with manual transmission that will not grind at times when you put it into reverse. It's as common as the turn indicator on a car not turning itself off while making a lane change on the freeway. There is no solution, just accept it, put the car in any forward gear, pull the clutch out enough to move the car forward an inch then go back into reverse.

The reason you grind gears in reverse is because the tranny is still spinning. come to a complete stop, Push in clutch, place in 1-5(to stop movement), then into reverse. If it still grinds then your pilot bearing is sticking or the clutch isn't fully releasing the clutch plate for whatever reason. Reverse is unsynchronized because the gear it's self doesn't move unless engaged. So if your having trouble pushing it in and it's not grinding then usually a little roll forward or just letting the clutch out and depressing it again will get the gear teeth to line up. Reverse doesn't have a helical cut, it's square and it isn't constantly meshed like your other gears are.

Ive just made a habbit of shifting into first and then into reverse everytime, and make sure youre at a complete stop. If you still have grinds then bleed your clutch line and adjust your engagement height.
When you go to put it in reverse and it doesnt go, its just because the teeth on the gear arent lined up and they wont mesh, they have a cone shape to them from the factory which helps it mesh but the more you grind the more those round off. If it doesnt go in when i push at reverse i just slowwwly let the clutch out as if im ready to drive in reverse and it slips in right as the clutch begins to engage and then youre on your way.

Me too I just shift into 1st move the car about a inch and then It slides right into reverse. If I dont it doesn't grind but it just wont go into gear. The w58 does not have a syncro for reverse.
