24. Disconnect the connector from the countershaft speed sensor (F).
25. Remove the bolt (G) securing the harness cover (H) then remove the harness cover from the mounting bracket (I).
26. Remove the primary heated oxygen sensor (Primary H02S) connector (A) from its connector bracket (B).
27. Disconnect the Primary H02S connector (A), and remove the Primary H02S harness from the harness clamp (C).
28. Remove the transmission housing mounting bolts (3).
29. Remove the nut (A) from the front mount (B), and remove the ground cable (C) from the engine.
30. Remove the front bulkhead cover (A), windshield wiper arms (B), cowl cover sealing (C), and cowl cover (D).
31. Lift and support the engine with an engine hanger, T/N AAR-T-12566, and support bar, T/N 07AAK-S3VA000, or equivalent. (The engine hanger and support bar are available through the American Honda Tool and Equipment Program.)
32. Remove the splash shield.
33. Remove the front sub-frame stiffener.
34. Remove the Primary H02S harness (B) from the clamp (C) on the transfer mounting bolt.
35. Remove exhaust pipe A.
36. Remove the spring clips (A) and castle nuts (B), and separate the lower arms (C) from the knuckles (D).
37. Insert a 6 mm Allen wrench (E) in the top of the ball joint pin (F), and remove the nut (G), then separate the stabilizer link (H).
38. Remove the cotter pins (I) and nuts (J), and separate the tie-rod end ball joints (K) from the knuckles.
39. Pry the left driveshaft out of the differential and the right driveshaft from the intermediate shaft.
40. Make a reference mark (A) across the propeller shaft (B) and the transfer companion flange (C), then separate the propeller shaft from the companion flange.
41. Remove the shift cable cover (A), then remove the bolts securing the shift cable holder (B).
42. Remove the change shaft (C) and the lock bolt (D) securing the control lever (E), then remove the shift cable (F) with the control lever. Do not bend the shift cable excessively.
43. Install a 6 x 1.0 x 14 mm bolt (A) and nut (B) on the shift cable cover (C), then reinstall the shift cable cover to the torque converter housing. If you don't do this, the bolt head of the cable cover may prevent you from removing the torque converter during transmission removal.
44. Remove the transfer assembly from the transmission.
45. Remove the torque converter cover (A), then remove the eight drive plate bolts (B) one at a time while rotating the crankshaft pulley.
46. Remove the engine-to-torque converter housing mounting bolts (C).
47. Disconnect the power steering pressure switch connector.
48. Remove the power steering hose clamp (A), then disconnect the hose (B) from the pipe (C) at the right front of the sub-frame (D).
49. Remove the transmission lower mount nuts (four).
50. Make reference marks (A) on the body across the marks (B) on the edge of the front sub-frame (C).
51. Remove the rear mount bracket bolts (three).
52. Loosen the four bolts (A) holding the adjustable arms (B) of the front sub-frame adapter (T/N EQS02BMDXB0) to its center plate.
NOTE: The adapter is designed to be use with the Acura transmission jack (model number LSL-W93714) or powertrain lift (model number OTC-1585), both available through the Acura Tool and Equipment Program. It will also work with most commercially available transmission jack.
53. Line up the slots in the arms with the bolt holes on the corner of the jack base, then attach the adapter to the jack base with the bolts (A) that came with the jack. Tighten all bolts securely.
54. Raise the jack to vehicle height, then attach the adapter to the front sub-frame using the subframe stiffener mounting bolts (B) and bolt holes.
55. Remove the 12 X 1.25 mm bolts (6) (A) securing the sub-frame stiffeners (B), the four sub-frame mounting bolts (C), and the stiffeners, then lower the front sub-frame (D).
56. Remove the transmission lower mounts.
57. Remove the driveshafts from the differential and the intermediate shaft. Coat all precision finished surfaces with clean engine oil, then tie plastic bags over the driveshaft ends.
58. Move the left driveshaft to the front side.
59. Remove the intermediate shaft.
60. Coat all precision finished surfaces with clean engine oil, then tie plastic bags over both ends of the intermediate shaft.
61. Remove the front mount bracket.
62. Remove the transmission housing mounting bolts.
63. Lower the transmission, and tilt the engine just enough for the transmission to clear its end cover from the side frame.
64. Place a jack under the transmission.
65. Pull the transmission away from the engine until it clears the dowel pins, then lower it on the jack.
NOTE: If the torque converter is stuck to the drive plate, pull it toward the transmission housing from the starter opening.
66. Remove the shift cable cover, then remove the torque converter assembly from the torque converter housing.
67. Inspect the drive plate, and replace if it's damaged.
68. Remove the 6 X 1.0 X 14 mm bolt that you installed on the shift cable cover in step 43.
