z Shift the transmission into reverse gear, then move the shift
lever forward to the position in between reverse gear and
neutral. Slowly release the clutch pedal (if the vehicle creeps
rearward, move the shift lever forward a little more). The
transmission will behave as if in neutral, but the reverse gear
synchronizer will be bypassed.
z With the clutch pedal up, gently pull the shift lever toward the
reverse gear position. Gear clash can now be heard.
z Slowly depress the clutch pedal. Using the steering wheel
inner seam as a reference, note the measurement when the
gear clash stops or the shift lever slides into reverse gear.

Install the gear selector interlock sleeve and the selector body as an assembly.
4. Lubricate the main shift control shaft with petroleum jelly.
5. NOTE: The 1-2 gear shifter fork is the larger shifter fork. The gear shifter fork offset lever must
face the cover. Position the gear shift plate attached to the 3- 4 gear shifter fork under the gear
shift plate attached to the 1- 2 gear shifter fork.
Position the gear shifter forks and the main shift control shaft in the cover. zSlide the shaft through the cover and shift the components until the shaft stops against
the cover.

z Inspect the output shaft for scoring or worn or damaged splines. Install new components
as necessary.
2. Lubricate all components with the recommended transmission fluid when reassembling.
3. NOTE: Position the output shaft with the output end facing upward.
NOTE: Install the synchronizer assembly with the deeper center flange of the synchronizer hub
facing toward the rear of the output shaft.

GENERAL PROCEDURES
Heater Hose Coupling
Disconnect
CAUTION: Do not attempt to install a new bushing, spacer or O- rings in the heater hose
coupling; damage to the heater hose coupling can result. If the heater hose coupling is the
cause of a coolant leak, the affected heater hose must be replaced as an assembly.
1. WARNING: The engine must be off, fully cool and the cooling system fully
depressurized before attempting to disconnect any heater water hoses. Failure to comply
with this warning can result in serious injury or burns from hot liquid escaping out of the
engine cooling system.
Depressurize the engine cooling system.
2. Push the heater hose toward the tube to fully expose the locking tabs.
3. NOTE: When compressing the white coupling retainer with the special tool, the special tool
must be perpendicular to and on the highest point of the coupling.
NOTE: If the heater hose coupling is accessible, the retainer tabs can be compressed by hand
to disconnect the heater hose.
Push the special tool over the coupling retainer windows to compress the retainer locking tabs.
