One of the most common problems with VW transaxles is their tendency to jump out of gear for no apparent reason.  Despite the best efforts of conscientious rebuilders to properly adjust shift forks,  tighten detent springs, even remove the "fat" drive teeth (bad idea) these gearboxes can still jump out of gear.  This is expensive and aggravating for both the customer and the rebuilder.  The reason for the failure of these linkage related attempts to fix the problem is simple:  The fork doesn't hold the slider in gearThe slider and gear stay engaged as long as there is correct tooth geometry.  Back in the 70ís, believing the slider to be the main cause of the problem, we developed a method to recut the flanks (sides) of the sliderís engagement teeth.  Extensive tests proved this unique machining process solves the jumping out of gear problem.

We found, unlike gears with their greater mass, the majority of sliders are out of round (most likely occurring during factory heat treating).  While rounded corners and unfavorable tooth angles are often apparent, small discrepancies in tooth spacing on the sliders generally cannot be seen.  This out-of-roundness and subsequent uneven tooth spacing causes some teeth to carry a greater burden of the load than others.  Many forward gears have only 3 sets of 3 "fat" drive teeth 120 degrees apart, (the remaining 21 "skinny" teeth carrying no load).  It is critical that the engagement teeth on the slider be able to contact all 'fat' drive teeth on the forward gear evenly.  Otherwise the uneven or asymmetric loading of the slider will cause the transaxle to jump out of gear.  Click here for more discussion on undercut tooth geometry.

Our remachined sliders have improved tooth geometry as the undercut produced is slightly steeper.  In addition, since the process removes very little material, excessive backlash is not a factor.  Our remachined sliders are capable of uniform engagement with the ability to stay in gear even in high horsepower, high load environments.
