Automatic Transmission - Disassembled View
NOTICE: Before beginning assembly, carry out and inspect the following:
When building up subassemblies and assembling the transmission, ALWAYS use new gaskets and seals.
All fasteners must be tightened to the torque specification indicated. In addition to appearing in the system, the necessary torques can be found in the General Specifications Chart.
When building up subassemblies, each component part should be lubricated with transmission fluid. It is also good practice to lubricate the subassemblies as they are installed in the case.
Needle bearings, thrust washers and seals should be lightly coated with petroleum jelly during subassembly buildup or transmission assembly.
Many components and surfaces in the transmission are precision machined. Careful handling during disassembly, cleaning, inspection and assembly can prevent unnecessary damage to machined surfaces.
36. NOTE: When installing the new seal, make sure that the drain hole in the seal is in the 6 o'clock position.

43. Install the 1-2 accumulator retaining ring.
44. NOTE: This is not an ordinary installation procedure and does not compensate for band wear. When new piston and rod assembly installation becomes necessary, or when a new reverse band has been installed, the reverse piston and rod length must be adjusted.
NOTE: Lubricate the reverse piston seal with transmission fluid to facilitate assembly and prevent damage to the seal.
NOTE: Do not install the reverse servo piston cover and seal at this time.

47. Loosen the bolt until the piston stops against the Dial Indicator Gauge stem.
48. Verify that the amount of piston travel on the Dial Indicator Gauge is within specification.
49. If piston travel is not within specification, select and install the correct servo assembly to bring the servo piston travel within specification.
1. 1 groove
2. 2 grooves
3. 3 grooves
50. Remove the Dial Indicator Gauge with Holding Fixture.
51. Install the reverse servo assembly.

54. Using the Transmission Air Test Plate, Transmission Test Plate Screw Set and Rubber Tip Air Nozzle, apply regulated air pressure to the test ports. Verify that the components are applied and released.
55. NOTE: The tab on the electrical connector is secured by the main control valve body.
Inspect the transmission internal harness connector O-ring for damage. If damaged, install a new O-ring. Install the electrical connector into the case.
56. NOTE: The alignment bolts are valve body assembly bolts and are in the valve body.
Align the main control valve body alignment bolts and position the main control valve body.
57. NOTE: The main control valve body bolts will be tightened in later steps.
Loosely install the 11 long main control valve body bolts.
58. NOTE: The main control valve body bolts will be tightened in later steps.
Loosely install the 12 short main control valve body bolts.
59. NOTE: Lubricate the EPC solenoid O-rings with transmission fluid.
Position the EPC solenoid bracket and loosely install the bolt.
60. Install the manual control valve detent lever spring and loosely install the bolt.

63. Install the transmission fluid filter and seal assembly.
64. NOTICE: The transmission internal wire harness needs to be properly routed to avoid the potential of damage to the harness. Pinched or trapped wires may result in a transmission failure.
Make sure the transmission internal wire harness is properly routed.
65. Position the magnet into the transmission fluid pan.
66. NOTE: The transmission fluid pan gasket is reusable. Clean and inspect for damage. If not damaged, the transmission fluid pan gasket should be reused.
