Capacities
NOTE: In all cases, the correct fluid level is es-
tablished by checking at the fill opening.
8. Operate the engine for five minutes after filling
the transmission, then check the fluid level again.
9. Clean the fill plug, then install it in the transmis-
sion. Tighten the plug as follows:
• 25 to 35 lbf·ft (34 to 48 N·m) for Eaton
Fuller transmissions with 3/4-inch pipe
threads.
• 60 to 75 lbf·ft (81 to 102 N·m) for Eaton
Fuller transmissions with 1-1/4-inch pipe
threads.
10. Operate the vehicle to check for correct opera-
tion.
26–03 Allison and Eaton Fuller
Transmission Breather
Check
If the transmission is equipped with a housing
breather (see
Fig. 3), it must remain clear. A plugged
breather could result in pressure build-up, which
could cause oil leakage.
IMPORTANT: Do not spray water, steam, or
cleaning solution directly at the breather. These
actions can force water or cleaning solution into
the transmission and contaminate the transmis-
sion fluid.
If the breather is plugged, clean or replace it. If re-
placing it, use a correct-size wrench (pliers or a pipe
wrench can crush or damage the breather stem and
produce metal particles that could enter the transmis-
sion).
Check more often if the vehicle is operating under
very dusty conditions.

NOTE: When the optional prognostics feature is
enabled on an Allison transmission, the system
monitors oil life and filter life. To reset the indica-
tor, press the Mode button (on the electronic
shift control) for 10 seconds with the ignition on
but the engine not running. For more informa-
tion, see the Allison Transmission website,
www.allisontransmission.com.
1. Park the vehicle on a level surface and apply the
parking brakes.
2. Operate the vehicle until the transmission

200°F (71 to 93°C).
