Remove all the transmission mounting bolts (bottom to top) from the engine. • When removing the two lower passenger side bolts, the passenger side gusset will drop free. • The upper driver side exhaust bracket bolt requires a 21” extension, universal joint, and 14 mm socket. Access to the bolt is gained from behind and above the lower portion of the transmission dipstick tube, outside of the selector rod. Loosen the lower exhaust bracket mounting bolt, and slip the bracket out of the way after the top two mounting bolts have been removed. • The remaining upper driver side mounting bolts require a 17 mm socket, universal joint, and 40” of extensions (two 20, etc.). Access to the bolts is gained from between the selector rod and transmission housing, driver side, at the rear section of the transmission oil pan. The transmission needs to be “hanging” to provide maximum tool clearance. (Do not remove the transmission jack, just lower it). • The upper passenger side mounting bolts require a 17 mm socket, universal joint, and 20” extension, Access to the bolts is gained from below the transmission, beside the gear box, passenger side. The transmission needs to be “hanging” to allow maximum tool clearance. (Do not remove the transmission jack, just lower it). 46. Once all the transmission-to- engine mounting bolts have been removed, raise the transmission until it is level (as close to it's original position as possible, with the converter housing equally spaced against the engine block). 47.

Remove the driver side lower gusset to allow access to the driver side torque converter inspection cover bolt. 49. Remove two torque converter inspection cover bolts and remove the converter inspection cover. 50. Remove six torque converter-to-drive plate mounting bolts. • This requires hand cranking the engine using a 21 mm deep socket and ratchet at the crankshaft pulley to gain access to the torque converter bolts. • Slide the transmission away from the engine approximately 2-3 inches, as necessary, to gain access to these bolts. 51. Simultaneously slide the transmission away from the engine as far as possible (without forcing), and slowly lower the transmission slightly. • Only lower the transmission enough to gain access to the upper electrical connectors, and to the crankshaft position sensor (located on the converter housing, driver side, near the top). • Lowering the transmission too far at this point could result in damaging the crankshaft position sensor, wire, or any／all of the three remaining connectors. 52. Remove the crankshaft position sensor bolt and remove the crankshaft position sensor. 53. Slowly lower the transmission (guiding the A／T control cable out of the engine compartment until it is clear). 54. Disconnect the 4WD Indicator Switch, 4WD Low Switch, and Vehicle Speed Sensor connectors. • Continuously check above and around the transmission as you lower it, to make sure all connectors have been disconnected, and that nothing is getting caught, or “hung-up” as the transmission lowers. • Disconnect any connected electrical connectors, and free anything that becomes caught by the transmission before continuing to lower the transmission. Failure to do so could result in damage to the transmission, electrical wiring, or the vehicle itself. WITH THE TRANSMISSION OUT OF THE VEHICLE, THE CENTER OF GRAVITY WILL SHIFT FORWARD SIGNIFLCANTLY. DEPENDING ON EXACTLY WHERE THE LIFT POINTS HAVE BEEN PLACED, FAILURE TO OBSERVE THE PRECEDING NOTICE COULE POTENTIALLY TIP THE VEHICLE, RESULTING IN SEVERE OR FATAL INJURY TO PERSONNEL. REMOVAL OF COMPONENT PARTS • Disassemble the transmission in a clean area (dust-free). • Place a rubber mat on the work bench to protect parts from damage. • When separating the case joint, do not pry with a screwdriver or similar tool, but lightly tap with a plastic hammer. • All disassembled parts should be carefully arranged for reassembly. • Wear eye protection when using compressed air to clean components. 1.
