IMPORTANT: These instructions cover only the routine 
maintenance of the transmission. Refer to the ZF 4

Cleanliness is of extreme importance. Before attempting 
any repairs, thoroughly clean the exterior of the 
transmission to help prevent dirt from entering while 
performing maintenance checks and procedures.
Section 6.6.2, “Transmission Maintenance Schedule” 
provides a suggested maintenance schedule with
