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:
MODEL PART NUMBER
M 15522264
C/K 15538302
G 15522263
