Silverado 1500 2WD V6-4.3L (2007)
Notice
The three clutch fluid seal rings are required to be installed in a specific way. Failure to install new clutch fluid seal rings may cause internal
transmission leaks and transmission damage.
6. Inspect and remove the three clutch fluid seal rings (1). Install new pump rings, GM P/N 24238248. Refer to 1-2-3-4 and 3-5 Reverse Clutch Fluid
Seal Ring Installation (6L80/90) in SI for correct installation.
7. After completing the repair procedure, a Service Fast Learn Adapts procedure must be completed. Refer to Service Fast Learn Adapts in SI for
procedure details. After completing the Service Fast Learn Adapts procedure, the vehicle may still experience some minor driveability issues but
should learn improved shifting performance over the next several key cycles and driving time. Review with the customer the facts about the
transmission's ability to self-correct shifting issues or concerns. The transmission adapts are always functional and operate at transmission oil
temperatures about 40°C (104°F).
