There ya go:

  1. Disconnect the negative and positive battery cables.
  2. Remove the battery.
  3. Support the hood as far open as possible. If you choose to remove the hood, first matchmark the hood hinge plates with a felt-tipped marker.
  4. Remove the console and shift boot. Unbolt the shift lever from the transmission case and remove it. Cover the quadrant box hole to prevent contaminants from entering the transmission.
  5. Raise and support the vehicle safely.
  6. Drain the transmission oil. Install the drain plug with a new washer.
  7. If equipped with a two-piece driveshaft, remove the center bearing retainer bolts.
  8. Matchmark the driveshaft to transmission and differential flanges. Remove the driveshaft.
  9. Remove the starter.
  10. Disconnect the speedometer cable.
  11. Disconnect the clutch cable from the release fork.
  12. Remove the exhaust pipe bracket from the transmission case. Disconnect the front exhaust pipe from the exhaust manifold and disconnect the second exhaust pipe.
  13. Use a lifting chain or jack to support the engine. Support the transmission with a jack.
  14. Remove the rear housing mount from the transmission. Remove the mount bracket from the No. 3 crossmember.
  15. Remove the quadrant box from the transmission.

The frame crossmember may interfere with transmission removal. An assistant will be helpful for shifting the transmission back and away from the engine.

  1. Position a jack under the transmission and remove the transmission case bolts. Move the transmission as far to the rear of the vehicle as possible to clear the mainshaft. Then, lower the clutch housing end of the transmission toward the jack and lower the transmission from the vehicle.

To install:
  1. Using a transmission jack, position the transmission-to-engine and tighten the retaining bolts to 28 ft. lbs. (37 Nm). Install the quadrant box.
  2. Install the mount bracket and tighten the bolt to 27 ft. lbs. (37 Nm).
  3. Install the frame-to-rear housing mount bolts at the No. 3 crossmember. Tighten the rear mount nut to 62 ft. lbs. (83 Nm).
  4. Tighten the engine mount nuts to 30 ft. lbs. (40 Nm).
  5. Install the exhaust pipe and bracket.
  6. Install the driveshaft and align the matchmarks. Tighten the center bearing bolts to 46 ft. lbs. (65 Nm). Position the retaining bolts with the head facing to the rear of the vehicle and tighten to 22 ft. lbs. (30 Nm).
  7. Install the speedometer cable and starter motor. Tighten the starter motor bolts to 30 ft. lbs. (40 Nm).
  8. Reconnect and adjust the clutch cable.
  9. Lower the vehicle and install the shift lever, shift boot, and console.
  10. Refill the transmission with the proper type of oil.
  11. Install the battery and reconnect the positive and negative cables.
  12. Install the hood if it was removed.
