i have a 1995 gmc 2500 with a 5.0 L AUTO 4X4
when i start my truck, very frequently the tach and speedo do not work at all, i believe causing the transmission not to shift. But the other guages do work ( gas. oil. temp. volts). on the other hand when i use my remote starter the tach does work until i turn the key on and hit the brake pedal (clearing the remote starter) then the tach drops to nothing. any help would be appreiciated, i'm stumped
