Transmission


















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.

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.

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.
