Transmission/Transfer Case/Steering Gear
and Pump Fluid
Recommended lubricant for the transmission, transfer case,
and steering system is Dexron III automatic transmission fluid.
Approximate fluid capacities are:
¥ 1 qt (0.95L) for the steering gear and pump
¥ 3.5 qts (3.3L) for the transfer case
¥ 13.5 qts (12.8L) for the transmission, converter, and
cooler
¥ 7.7 qts (7.3L) for the transmission (during fluid drain/re-
fill)
Brake Fluid
Recommended brake fluid for all Hummer vehicles is DOT 3
brake fluid. Master cylinder approximate capacity is 1.64 pints
(0.78L). Brake system approximate capacity is 3.1 pints
(1.5L).
Front/Rear Axle and Geared Hub Lubricant
Recommended lubricant for axles and hubs is a heavy duty,
multipurpose, API GL-5 gear lubricant, with viscosity ratings
of 80W-90 or 75W-90.
The 80W-90 is an all purpose lubricant. The 75W-90 lubricant
is suggested for use in areas where winter temperatures are
consistently below freezing.
Steering Linkage and Suspension Lubricant
Recommended lubricant for steering and driveline components
is an NLGI LB, or GC-LB grade multipurpose chassis grease.
Use only those lubricants that display the NLGI certification
symbol.
Body Lubrication
Door hinges, linkage parts, cables, and other body components
can be lubricated with a number of different lubricants. Sug-
gested lubricants and applications are:
¥ Window regulator mechanisms Ð spray white grease
¥ Window slides Ð silicone spray lube
¥ Door hinges Ð engine oil, ATF, or LPS brand spray lube
¥ Linkage/cables Ð LPS brand silicone spray lube
¥ Lock strikers Ð chassis grease, white grease, or LPS #3.
¥ Seat track Ð multipurpose chassis grease (NLGI-LB)
¥ Lock mechanisms ÐATF, silicone spray lube, graphite
lube
