Summary
This Preliminary Information communication provides information to the technician about vehicles that may have a delayed engagement into drive, shudder at a launch, or the transmission is slipping when shifting into 1st, 2nd, 3rd or 4th gears. This may be due to loose stator support to pump cover bolts causing a leak at the stator support to pump cover gasket. Technician will check for the bolts to be loose. If any of the bolts are loose or the gasket is misaligned or leaking, the transmission pump cover must be replaced and the 1234 clutch plates should be inspected for being distressed and repaired as needed.
Condition / Concern
Customers may comment on a delayed engagement into drive, shudder at a launch, or the transmission is slipping when shifting into 1st, 2nd, 3rd or 4th gears.
The customer may also comment that they feel a bump or hear a clunk noise during a 1-2 shift.
These concerns may only be present when the transmission is at operating temperature.

The following information only applies to transmissions with a source code (item number 7 in document 2610129) of (2). Supersession Statement: This PI was superseded to add the MYB 6L60 and model years. Please discard PIP5175D. Condition / Concern Customers may comment on a delayed engagement into drive, shudder at a launch, or the transmission is slipping when shifting into 1st, 2nd, 3rd or 4th gears. The customer may also comment that they feel a bump or hear a clunk noise during a 1-2 shift. These concerns may only be present when the transmission is at operating temperature. Recommendations / Instructions These concerns may be due to loose stator support to pump cover bolts causing a leak at the stator support to pump cover gasket. If the root cause cannot be found following normal SI diagnostics, remove the transmission fluid pan and the transmission control assemblies. Referring to the picture below and wearing proper eye protection apply compressed air to the 1-2-3-4 clutch apply passage and inspect for air leaking out of the compensator feed passage in the pump cover. If no leakage is found out of the compensator feed passage listen for excessive air leakage inside the transmission. Callout 1 Component Name: Applying compressed air to the 1234 clutch passage. Callout 2 Component Name: Compensator feed passage. You may also notice fluid leaking or see a misaligned gasket by looking up through the case opening between the pump stator support and the 1234/35R clutch housing during this test as shown below. Callout 2 Component Name: Gap between the pump cover and the 1234/35R clutch housing. If excessive air leakage is found inspect the transmission fluid pump for loose stator support to pump cover bolts or a misaligned stator support to pump cover gasket. Note: The bolts should never be checked for being loose by using a hand tool. The bolts are supposed to be torqued at the factory and never loosened. The recommended procedure to check for loose bolts is to use your fingers or just a socket and your fingers and attempt to rotate the bolts in a counter clockwise direction. If the bolts are loose for any reason the pump cover must be replaced. Refer to the picture below. Callout 1 Component Name: Misaligned Gasket Callout 2 Component Name: Stator Support Bolts If any of the bolts are loose or the gasket is misaligned or leaking, the transmission pump cover must be replaced and the 1234 clutch plates should be inspected for being distressed and repaired as needed. Note: The transmission adapts must be reset if the pump cover is replaced to address this concern.
