REMOVAL & INSTALLATION
Borg-Warner and JM600
- Jack up the front of the car and support it safely on stands.
- Slide a drain pan under the transmission. Some late model JM600 transmissions are equipped with an oil drain plug. On these models, loosen and remove the plug to drain the fluid. On models not equipped with a drain plug: Loosen the rear oil pan bolts first, to allow most of the fluid to drain off without making a mess on your garage floor.
- Remove the remaining bolts and drop the pan.
- Discard the old gasket, clean the pan, and re-install the pan with a new gasket.
- Tighten the pan bolts to 8-13 ft. lbs. on the Borg-Warner and 4-6 ft. lbs. on the JM 600 in a criss-cross pattern.
The transmission case is aluminum, so don't exert too much force on the bolts.
- Install the drain plug, on models equipped. Fill the transmission through the dipstick tube. Check the fluid level as described in .
- Jack up the front of the car and support it safely on jackstands. Place a drain container with a large opening, under transmission and pan.
- Loosen pan bolts and tap the pan at one corner to break it loose allowing fluid to drain, then remove the oil pan.
- If necessary, adjust the reverse band.
- Install a new filter on bottom of the valve body, and tighten retaining screws to 35 in. lbs.
- Clean the oil pan, and reinstall using a new gasket. Tighten oil pan bolts to 150 in. lbs. in a criss-cross pattern. Lower the car.
- Pour four quarts of DEXRON®II type automatic transmission fluid through the filler tube.
- Start the engine and allow to idle for at least two minutes. Then, with parking brake on, move selector lever momentarily to each position, ending in the neutral position.
- Add sufficient fluid to bring level to the ADD 1 PINT mark. Check fluid level after transmission is at normal operating temperature. The level should be between the FULL and ADD 1 PINT mark.
