The 76mm and 89mm four-speed transmissions may develop a "stuck in gear" condition. This condition may be caused by the external
shifter assembly slipping into neutral. This happens because the 1-2 shift lever is chamfered, allowing the selector pin to slide past the
lever into a neutral position while the transmission remains in gear.
An improved shifter has been released eliminating the chamfer on the 1-2 shift lever. The shifter may be used on past models to replace
worn or damaged shifter assemblies. The shifter part number for each model are as follows:

C/K

G
