If the car will move in reverse but won’t go forward, the likely cause is worn out solenoids, clutches, or gears. Check the transmission fluid, as a low level is a potential reason for making the car move in reverse only.

Fluid is good it is a 2wd truck but I am getting a c1500 trouble code which is transfer case encoder circuit b fault and when put in any gear other then reverse it idles up extremely high I am bum founded because no burnt fluid and trans worked perfect one day and it sat for a month and now nothing but reverse
