  16.  
  17. Pull the transmission straight back and remove it from the vehicle.
  18.  

To install:

Installation is the reverse of removal, but please note the following important steps.

  1. Make sure the torque converter is fully seated in the pump drive. If not, the transmission will not fit tightly to the rear of the engine block.
  2.  
  3. Raise the transmission into position and remove the torque converter holding strap. Carefully slide the transmission forward until the dowel pins are engaged while lining up the marks on the flywheel made during removal.
  4.  
  5. The torque converter should be flush with the flywheel and turn freely by hand.
  6.  
  7. Install the transmission-to-engine nuts, studs and or bolts. Tighten the studs and/or bolts to 37 ft. lbs. (50 Nm).
  8.  
  9. Tighten the bolts securing the heat shield to the transmission to 13 ft. lbs. (17 Nm).
  10.  
  11. Tighten the bolts and washers securing the transmission mount to 18 ft. lbs. (25 Nm).
  12.  
  13. Tighten the nut and washer securing the transmission mount to the transmission support to 35 ft. lbs. (46 Nm).
  14.  
  15. Refill the transmission with the proper amount and type of fluid.
