Removal Procedure

Important: 

   • Ensure that the control lever is positioned into the mechanical third or fourth gear prior to removal of the shift lever from the transmission. The transmission must remain in this state when the shift lever is removed.
   • Do not disassemble the transmission shift lever. Internal parts for this shift lever are not available. Opening the shift housing lever voids the warranty.
   • When removing the shift lever from the transmission, use the exposed bolts on the base of the lever.
