  10. On 4WD vehicles, remove the transfer case from the vehicle.
  11. Remove the starter motor.
  12. Position a transmission jack, under the transmission.
  13. Remove the transmission-to-engine retaining bolts and washers.
  14. Remove the nuts and bolts attaching the transmission mount and damper to the crossmember.
  15. Remove the nuts and bolts attaching the crossmember to the frame side rails and remove the crossmember.
  16. Lower the engine jack slightly to angle the transmission assembly. Work the clutch housing off the locating dowels and slide the clutch housing and the transmission rearward until the input shaft clears the clutch disc.
  17. Lower the transmission jack and remove the transmission from the vehicle.

    To install:

  18. Check that the mating surfaces of the clutch housing, engine rear and dowel holes are free of burrs, dirt and paint.
