If you are nicking reverse when 5-4 downshifting, then the reverse lock-out is not working properly.


The problem comes from having the shift coupler adjusted improperly. If the shift lever is not far enough forward in the housing when 5th is fully engaged, then the lever never makes it past the lock-out.

Installing a short-shifter will only make the problem worse, since the throws are shorter. So you have to set the adjustment so that the neutral gate is slightly forward of the center line between the 5th and reverse resting plates on the toip of the shifter.


If the reverse lock-out is working properly, then you should never move the lever into the neutral gate, wiggle it around, then engage 4th, because then you are defeating the reverse lock-out action. It should be a smooth pull straight back, as the lock-out will guide it right into 4th, so long as it's properly adjusted.

I suggest removing the rubber boot, and watching the lock-out while you do some 4-5 and 5-4 shifts. It will begin to make sense once you see what it's supposed to be doing.
