Aluminum shell 10R80 10L90 HL3P-7B177-CD 24289480

The aluminum outer cylinder, which is the housing for the internal components of the transmission, has received the ironic nickname "garbage can" in the professional environment, is one of the most vulnerable components of the 10R80 transmission.

Let's consider the main problems caused by the aluminum shell.

1. Damage to the inside of the shell by the teeth of the F Clutch friction discs.

When the teeth knock out the grooves on the shell body, the teeth get stuck in these grooves, making it difficult to engage and disengage the F Clutch.
A free play problem with the disc getting stuck in the shell housing causes the clutch discs to slip, which can cause a 3-5, 5-3 shift problem or a 2-4, 4-2 shift problem.
There may also be problems with engaging and disengaging reverse gear, as well as with shifting gears 3-4, 4-3.

2. Damage to the inner part of the shell by the teeth of the planetary gear housing P1.

If you remove this unit, then upon careful examination of the place where it is attached to the cylinder, you can see damage to the aluminum shell body.

This allows the underside of the P1 planet housing to fall and rub against the P2 planet housing. This will also cause metal shavings to be spread throughout the transmission.
