about a month ago i was having trouble being able to select 5th and reverse ...
i couldn't move the shifter all the way to the right, i can feel the feed back of the shifter but i can only go so far. if i drove around for awhile i could get the gears back... now i cant seem to get 5th or reverse at all .... i check the shift linkage and i have replace the bitch pin.... any ideas would be awsome.

 

jack the car up and look under the car and see if ur exhaust is in the way of the shifter when shifting to the far right where reverse and 5th gear are. it sounds like u have something in the way keeping u from getting in gear...

 

I have it up right now and everything is clear of the linkage assembly, i am under the car moving the linkage around and nothings hitting it nor rubbing against it .... crap, thinking it might be the sleeves in the tranny. its not the synchros, when i can select 5th and reverse the gears are nice and smooth.
