Transaxle Disassembly

Transaxle













Disassembly

1. NOTICE: If, during repair work, abrasive particles are found in the transmission fluid (particles from the clutch or metal chips or foreign material), the transaxle must be disassembled completely and thoroughly cleaned. Also, clean the fluid tubes, fluid cooler and torque converter carefully. In the case of extreme soiling of the fluid pipes, install a new fluid cooler and torque converter.

NOTE: In case of clutch abrasion, rinse the torque converter with clean automatic transmission fluid.

Inspect the transaxle during disassembly.

- Using a suitable tool, remove the transmission fluid pan.





36. Clean the silicone from the transmission fluid pan and transaxle case surfaces thoroughly with metal surface prep.

37. Disconnect the Transmission Fluid Temperature (TFT) sensor.





38. Remove the transmission fluid filter.





39. NOTE: It is necessary to note the location of the main control wire harness connectors so they can be connected in the same positions. Connector color letters are cast into the solenoid body.

Remove the main control ground wire bolt, disconnect the electrical connectors and remove the wire harness.

1. Shift Solenoid C (SSC), color N (white).

2. Shift Solenoid E (SSE), color G (green).

3. Shift Solenoid D (SSD), color L (blue).

4. Line Pressure Control (LPC), color B (black).

5. Shift Solenoid A (SSA), color N (neutral).

6. Shift Solenoid B (SSB), color B (black).





40. NOTE: Note the locations of the longer bolts.

Remove the 13 main control valve body bolts.





41. NOTE: Squeeze the tabs on the side of the electrical connector.

Remove the transaxle internal harness electrical connector.





42. NOTE: Each accumulator piston has 2 springs inside of them, totaling 4 springs. All 4 springs are different sizes. The accumulator piston bore and accumulator pistons are a match as to depth. Some of the accumulator piston may have steps. Take note of the size, depth and location of the accumulator pistons and the spring sizes to aid assembly.

Remove the accumulator pistons and springs.





43. Remove the manual control lever shaft roll pin.





44. Remove the manual control lever shaft.





45. Remove the O-ring seals from the manual control lever shaft.





46. Remove the manual control lever detent assembly.





47. NOTICE: The intermediate/Overdrive (O/D) band servo cover plate is spring loaded. The bolts should be removed evenly until plate is unloaded, then remove the bolts. Failure to do so can result in bolt thread damage.

Remove the 3 intermediate/O/D piston servo cover bolts and the servo cover.





48. Remove the O-ring seal.





49. Remove the intermediate/ O/D servo piston.





50. Remove the intermediate/ O/D servo piston return spring.





51. Rotate the transaxle 180 degrees.

52. Remove the bolts and separate the converter housing from the transaxle case.





53. Remove the differential assembly.





54. Remove the parking pawl assembly cover.
- Remove the bolts and the parking pawl assembly cover.





55. Remove the parking pawl abutment.

1. Unclip the spring.

2. Remove the pin.

3. Remove the lever.

4. Remove the parking pawl abutment.





56. Remove the spring.





57. Remove the transfer shaft gears.





58. Using the Final Drive Input Gear Holding Tool, lock the final drive input gear.
