Manual. 5 Speed. Works wonderful until I try to get into 5th gear, then (it feels like 5th position) it goes into 3rd gear. Ive checked with the linkage and everything. Adjusted it all over the place and still haven't gotten it to grab the 5th gear. Is it possible its just transmission fluid or do i need to purchase a new 5th gear? Doesn't even register as a gear when shifting, no matter the RPM's or speed.
