While going from 3rd to 4th and whenever I step on or release the gas in 4th regardless of speed something vibrates. Sometimes I feel the vibes through the gas pedal. It seems as though the vibration is something trying to keep up if that makes any sense. It almost seems like it's the drivetrain that goes into the transmission. My truck is a 61'W200 with a 420 transmission, my transfer case is a 201 New Process. Any and all help appreciated!!
