Installation Procedure
- Apply a thin coat of J 36850
to all of the components prior to assembly.
- Install the gearshift lever case seat into the gearshift lever
case.
Notice: Use the correct fastener in the correct location. Replacement fasteners
must be the correct part number for that application. Fasteners requiring
replacement or fasteners requiring the use of thread locking compound or sealant
are identified in the service procedure. Do not use paints, lubricants, or
corrosion inhibitors on fasteners or fastener joint surfaces unless specified.
These coatings affect fastener torque and joint clamping force and may damage
the fastener. Use the correct tightening sequence and specifications when
installing fasteners in order to avoid damage to parts and systems.
- Install the following
components into the gearshift lever case:
3.1. | The two lever locating bolts (1) |

limit bolt (1) into the gearshift lever case.
Tighten
Tighten the reverse gearshift limit bolt to 35 N·m (26 lb ft).
Important: Position the portion of the gearshift shaft which has been machined
flat so that it faces downward, toward the inside of the gearshift lever case,
in order to ensure correct installation.

installing the following components onto the gearshift shaft:
5.1. | The gearshift lever (3) |
5.2. | The reverse gearshift limit yoke (1) |
5.3. | The gearshift limit spring (2) |
- Install the gearshift lever case plug into the gearshift lever
case.
- Stake the gearshift lever case plug in 2 places.
- Install one roll pin into the reverse gearshift limit yoke.
- Install the following
components into the gearshift arm (1) and the gearshift shaft:
- Install one roll pin into the gearshift shaft in order to retain
tension on the gearshift limit spring.
- Install the gearshift control lever bushing into the gearshift
arm.
- Install one inner and one outer roll pin into the gearshift arm
and the gearshift shaft.
- Attach the hooked end
of the gearshift limit spring (3) around the roll pin (1).
Wind the gearshift limit spring until the straight end can be fitted
into the groove on the reverse gearshift limit yoke.
- Install the following
components into the gearshift lever case:
14.1. | The 2 select guide pins (3) |
14.2. | The 3 select return springs (2) |
14.3. | The 2 select return spring bolts (1) |
Tighten
Tighten the select return spring bolts to 23 N·m (17 lb ft).
- Apply Loctite™ 414 GM P/N 1345493 or equivalent to the threaded
portion of the reverse gearshift limit bolt.
- Apply Loctite™ 599
RTV silicone sealer or equivalent to the gearshift lever case plate mating
surface (1) on the gearshift lever case (2).
- Install the gearshift lever case plate (3) onto the bottom of
the gearshift lever case (2).
Secure the gearshift lever case plate (3) with the 4 screws.
