Diagnostic Aids

WARNING: This page does not describe the selected car, but rather 12 other vehicles, including the 2002 GMC Savana Special, 2002 GMC Savana Camper Special, 2002 GMC Savana, 2002 Chevrolet RV Cutaway, and 2002 Chevrolet Cutaway. 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.

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