Tools Required
J 33037 Band Apply
Pin Tool
- Install the band apply
pin and the J 33037
.
- Install the servo cover retaining ring to secure the tool.
- Apply 11 N·m (98 lb in) torque. If the white
line appears in the gauge slot, the pin length is correct.
- If the white line is not seen in the slot, replace the pin using
the following pin identification:
• | One groove, pin length 65.82--66.12 mm (2.59--2.60 in) |
• | Two grooves, pin length 67.23--67.53 mm (2.65--2.66 in) |
• | No grooves, pin length 68.64--68.94 mm (2.70--2.71 in) |
- Remove the pin and the J 33037
.
- Check the 2nd apply piston
and the housing dimension.
- Measure the piston (25) dimension (1)
- Measure the housing (22) dimension (2)
- Check the chart for the transmission and piston/housing specifications.

Installation Procedure
Tools Required
J 29714-A Servo Cover
Compressor
- Install the 2-4 servo
assembly into the 2-4 servo bore.
- Install the J 29714-A
.
- Tighten the bolt in order
to compress the servo cover.
- Install the servo cover retaining ring.
- Remove the J 29714-A
from the oil pan flange.
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 oil pan
bolt.
Tighten
Tighten the oil pan bolt to 11 N·m (97 lb in).
- Lower the vehicle.
- Check the automatic transmission fluid level and install new automatic
transmission fluid as needed. Refer to
Transmission Fluid Check
and
Fluid Capacity
.
