Note: Contact the JLG Service Department if internal
transmission repair is required during the warranty
period.
Note: Cleanliness is of extreme importance. Before
attempting to remove the transmission, thoroughly clean
the exterior of the transmission to help prevent dirt from
entering during the replacement process. Avoid spraying
water or cleaning solution onto or near the transmission
shift solenoids and other electrical components.
