Just had my campervan give me the first bit of trouble. The gear stick just recently was sticking in reverse, so I crawled underneath and oiled everything up. Went back in to check the gear stick again and it felt better, but then it got stuck again, when I gave it a little shove to get it out of reverse, it stopped shifting into anything. The gear stick doesn't move at all. The cables are fine, if I detach them at the gearbox, the stick will move. The actual shift rod and levers on the gearbox seem like they have lifted up?? Any ideas?? Hoping maybe it is something I can fix myself, but figured I should ask in case.
