if it is the Isuzu 5-speed transmission. It takes a special lube. its Gm part #
12345349. it takes 4.0 pints. the drain plug is on the left side and the check plug is on the top right.

If it is the Muncie,New Venture 5 speed Transmission, it also takes the special lube gm part # 12345349. the drain plus is on the bottom and the check plug is on the top.
