Transmission Oil Change on a M35A2 Deuce and a Half
This guide details a transmission oil change for an M35A2 Deuce and a Half military truck. It covers removing the transmission cover, identifying and draining the old GL-1 or GL-5 fluid, and refilling with 30 weight non-detergent motor oil, which is stated as the manufacturer's original specification. The process includes checking the fluid level by inserting a finger into the fill hole to the first knuckle and notes that the new oil may improve shifting, particularly into second gear.
