    I have an 83 with 4 speed manual trans. I'm pretty sure its the muncie version. Its jumping out of 3rd gear under load and when going from load to coasting. If I hold it in it will stay in gear. When it pops out of 3rd if I dont take the shifter to neutral before trying to put it back in gear it will grind. Any ideas what this would be? shift forks? syncros? Can I reach them through the cover on the side of the trans front left.

    I do not mean this in a bad way but search this subject . There is a whole bunch of great info on that problem .

    It is very common and skip third gear until you can make repairs.

    Shift fork was the fix for me.

    I did search. I didnt find much on it. Maybe I should be typing in a different phrase. My main question was if its the shift forks can I reach them through the side cover?

    Thanks

    The side PTO covers will not let you get at the forks.

    You"ll need to remove the top cover - just as a note - the shifter needs to be in reverse to take the cover off.

    All that stuff is a waste of money IMO. They do not even mention worn forks as a problem, which worries me since they are supposedly experts.
