Diagnostic Aids

WARNING: This page is about a different car, the 2002 GMC Yukon XL, 2002 GMC Sierra, 2002 Chevrolet Suburban, and 2002 Chevrolet Silverado. However, it is still accessible from the selected car via links, so may be relevant.

Verify that the transmission meets the specifications in the SHIFT SPEED SPECIFICATIONS  under PERFORMANCE TESTS.

Other internal transmission failures can cause more than one shift to occur. See SHIFT SOLENOID VALVE STATE & GEAR RATIO  table under DESCRIPTION & OPERATION.

DTC P0752 defaults to an elevated line pressure condition which may result in TCC partial apply. This may induce idle surge and engine stall.
