Fuller transmissions with 3/4-inch pipe
threads.
•

Fuller transmissions with 1-1/4-inch pipe
threads.

tion.

Level Inspection
NOTICE
Operating a transmission with the fluid level
higher or lower than recommended can result in
transmission damage. Do not overfill the transmis-
sion.
Do not mix types and brands of fluid, because of
possible incompatibility. Do not use fluid addi-
tives, friction modifiers, extreme-pressure gear
fluids, or multiviscosity lubricants.
