2009 Chevrolet Express 2500 QuestionsIs it my transmission, transfer case or both (1 answer)
Shifts very hard with a thump from first to second gear and a bit less from second to 3rd. Can feel the shift hard in the rear only. Nothing from transmission area.
Looking for advice/direction on where to start diagnosing the 1.6 AMP draw. Short to ground, bad relay, pull one fuse at a time while measuring AMPS? If the AMPS drop then check each component on that fuse/circuit? What are acceptable parasitic drain levels... 25-30 mA ?
2009 Chevrolet Express 2500 RecallsInsufficient Instrument Panel Padding
Certain vehicles are being recalled because if a crash were to occur not requiring deployment of the front airbags, the head of an unbelted front seat passenger could hit the instrument panel, resulting in personal injury because the panel may not sufficiently absorb the impact. As of this writing, General Motors is still working on a remedy for this concern.
The heating and AC control knobs may fracture and spin on the control shafts. The driver may not be able to control the heating and ventilation for the vehicle. If this happens when the defrost system is needed, visibility could be reduced, which could lead to a crash. Dealers will replace all of the heating and AC control knobs free of charge. The recall began March 11, 2010. The GM recall number is 10012.
