Chevrolet Express 2500 ProblemsCheck Engine Light With Code P1870
Vehicles equipped whit a 4 speed automatic transmission may develop a harsh 1-2 shift and/or illumination of the Check Engine Light with code P1870 stored. This can be caused by wear of the bore for the TCC isolator and regulator valves in the valve body. This condition does not commonly occur until the transmission reaches normal operating temperature. If the valve body is worn, replacement will be necessary to correct this concern.
The fuel pump may fail causing the engine to stall and not restart.
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.

The chassis electrical module can short due to internal contamination. This can result in the vehicle stalling. Dealers will replace the chassis electronic module free of charge to resolve the concern.
Certain vehicles equipped to run on compressed natural gas are being recalled because the high pressure natural gas regulator could develop a leak, increasing the risk of a fire or explosion. Dealers will replace the natural gas regulator to correct this concern.
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.
