GMC 1500 Pickup Problems

Check 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.

Replace Fuel Filter Every 30,000 to Prevent Fuel Pump Failure

The fuel pump may fail causing the engine to stall and not restart. Our technicians recommend replacing the fuel filter every 30,000 miles to help prevent undue strain on the fuel pump.

Windshield Wipers May Fail Due to Faulty Wiper Motor Control Board

The windshield wipers may not work intermittently due to a faulty wiper motor control board. Our technicians tell us that lightly taping on the wiper motor when the fault occurs should temporarily get the wipers working again. Some vehicles were recalled for this problem and some were not. You will need to check with your local dealer to find out if a specific vehicle was included.

Dash and gauge lights are too dim... New switch does not fix the problem...
1995 GMC 1500 5.0L. 280K and still running strong. Had to replace intake gaskets twice, heater hose connectors and fuel pump. Only run 20w50 Castrol with Lucas oil stabilizer. I believe that is the secrete to a strong running 305.
