|John Capehart||My 4230 Quad Range pops of of A and B occasionally. I've read that a spring could be at fault, though manually holding the lever in A does not prevent it popping out - there seems to be considerable force pushing on the lever. Any thoughts?
|wolfie||You can try to tighten the lower shifting cam and change the detent and spring first. (Follow the shifting linkage down to the lower bellcrank and try to pull the attached shaft out of the tranny. It should have very little endplay.) If it still jumps out after adjusting it (providing the linkage isn't pulling it out of gear),you will problably have to replace a couple of shift collars and possible gears if it is too bad.
