TRANSMISSION CLUTCH FILL CALIBRATION - CONTINUED
N OT E
Hydraulic fan speed is controlled by transmission oil temperature during transmission clutch fill calibra-
tion.
e.
Display area will show these setup conditions:
(1)
Warm transmission oil to proper temperature. Temperature required to start calibration is different from
temperature required to maintain calibration procedure.
(2)
Temperature for START of calibration must be 181 to 194F (83 to 90C).
(3)
Temperature for MAINTAINING calibration must be 167 to 208F (75 to 98C).
(4)
Place transmission direction and shift lever in NEUTRAL position.
(5)
Engage parking brake (TM 5-3805-290-10).
(6)
Operate engine at high idle.
f.
Perform these procedures to satisfy setup condition.
(1)
To warm transmission oil:
(a) Engage parking brake (TM 5-3805-290-10).
(b) Place autoshift switch in MANUAL position.
(c) Ensure transmission neutralizer override is enabled. Transmission neutralizer override is enabled
when transmission neutralizer switch is illuminated (TM 5-3805-290-10).
(d) Place transmission direction and shift lever in third gear position (TM 5-3805-290-10).
(e) Shift transmission direction and shift lever in FORWARD position (TM 5-3805-290-10). Since park-
ing brake is engaged, transmission direction and shift lever must be shifted to FORWARD position
twice within two seconds to shift transmission.
(f) Operate engine at high idle (TM 5-3805-290-10). Use throttle lock to set engine high idle speed (TM
5-3805-290-10). Monitor gage on instrument panel for transmission oil temperature. Reduce engine
speed when gage enters high temperature area.
(2)
Use MSD calibration screen to monitor transmission oil temperature.
(3)
Maintain transmission oil temperature displayed by MSD between 3 and 5 minutes to properly heat up
transmission.
(4)
While transmission temperature is maintained, perform this procedure to warm hydraulic oil:
(a) Disengage hydraulic lockout (TM 5-3805-290-10).
(b) Stall raise circuit for 30 seconds (TM 5-3805-290-10).
(c) Stall tilt circuit for 30 seconds (TM 5-3805-290-10).
(d) Alternate stalling raise circuit and tilt circuit until hydraulic oil reaches normal operating temperature.
Oil is at normal operating temperature when needle on hydraulic oil temperature gage is at midpoint
of gage.
(e) Engage hydraulic lockout (TM 5-3805-290-10).
