yeah i pulled ou tthe shifter and tried with a screwdriver, it just wont let me get into 4th,
and yes i can still get reverse,
one thing i noticed was, if i pushed really hard in the direction of 4th, then i have to push really hard to get into any other gear,
once i get it into a different gear, pull it out, then its easy to change gears again.
(still without 4th obviously)
