My 2003 Club Car DS pops into neutral when going forward unless I physically hold down the gear selector in the forward position to keep it from doing so. I cannot figure out why.
Popping out of gear is a common problem when it comes to manual transmissions. The most common reason a manual transmission would jump out of gear is due to low or contaminated fluid, worn synchronizers inside the transmission, or improperly adjusted shift linkage. Also I suggest that the transmission mount is checked for excessive wear because bad mounts have been verified as a fix to similar concerns.
You have to adjust the cables because they stretch over time
