racinfool40 202 #2 Posted June 11, 2014 well, Could be a number of things...weak spring and detent ball in the high/low shift fork..Bent shift fork which wont let is seat completely gears rounded over which would cause it to push it out of gear..And the only way to tell is you gonna have to pull it and split the trans.. 1 Share this post Link to post Share on other sites
