Section 3 Production Line Procedures
3.1 Assembly Procedures
3.1.1 Storage Requirements
The transmission shipping containers are designed to protect the transmission from some environmental conditions.
They are only effective if they are properly closed. Verify the top cover on the cocoons is properly aligned to
insure no foreign materials such as water can get inside. Transmissions should remain in shipping cocoons until
engine marriage. Transmissions should be stored in a dry, dust free environment at room temperature. Do not
store outside. Even if they are in the cocoons, there is still a risk for water and other foreign mater to get inside. If
water accumulates inside the cocoon, there are no drain holes for it to escape. The resulting condensation cycles
will insert water and debris into the transmission fluid and cause permanent damage. Water damage will void all
warranties.
3.1.2 Handling Requirements
Transmissions should be assembled to vehicles in a timely manner to avoid contamination risks or damage
during the storage period.
Transmissions should be lifted from appropriate shipping racks by approved lifting hooks. The lifting hooks should
be designed to allow the following:
1. Lift the transmission by at least two lift points.
2. Employ one counter balance arm to ensure that the transmission is lifted straight up from the rack and it does
not swing or tilt.
3. Lift hook must include a safety latch to prevent the transmission from sliding off the hook during lifting.
4. The hooks utilized to lift and place the transmission parallel to the engine should position the transmission so
that the torque converter will line up with the flywheel and fit squarely on the engine block alignment features.
The transmission should not be allowed to tip forward. The torque converter may be disengaged from the
transmission causing injury or damage, or it may move away from the transmission bell housing far enough to
disengage from the oil pump (pump could be damaged).
Once the transmission is removed from the cocoon, the transmission shall not be set down on the bottom pan
or be allowed to contact any sharp or hard objects. Damage to the oil pan, gaskets, or internal components may
result from resting transmissions on their bottom pans. If transmissions must be staged, they should be placed
on approved racks that allow them to sit on oil pan bolt heads.
Transmission storage time should be held to a minimum by using a first-in/first-out process.
