Overhaul

36. Remove the front planetary sun gear and shell assembly.





37. Clean and inspect the front planetary sun gear and shell assembly for damage or wear and install new, if necessary.

- Sun gear teeth

- Shell-to-clutch pack surfaces

- Bearing surfaces





38. Remove the No. 10 front sun gear thrust bearing.





39. Remove the front planetary carrier hub assembly.





40. Clean and inspect the front planetary carrier hub for damage or wear and install new, if necessary.

- Spline teeth

- Thrust bearing surfaces

- Hub-to-stator support surfaces





41. Remove the No. 11 support assembly thrust bearing.





42. NOTE: Note the orientation of the snap ring for assembly. The snap ring gap must fit around the tab of the low/reverse clutch pressure plate.

Remove the low OWC (One-Way Clutch) snap ring.





43. Remove the low OWC (One-Way Clutch).





44. NOTICE: Do not clean in water or with water-based solvents. Damage to the component may occur.

NOTE: The low OWC (One-Way Clutch) cannot be disassembled.

Clean and inspect the low OWC (One-Way Clutch) for cracks and damaged splines. The internal splined section should rotate counterclockwise and lock when rotated clockwise. If any damage is found or the clutch does not rotate or lock, install a new low OWC (One-Way Clutch).





45. Inspect the forward clutch surface for damage. If the surface is burned or worn excessively, install a new OWC (One-Way Clutch).





46. Remove the forward clutch assembly.





47. NOTE: Install 307-584/1 with the stepped end of the cylinder facing upward when compressing the forward clutch piston return spring.

Using 307-584/1, 307-584/2, 307-574/1 and 307-574/2 compress the forward clutch piston return spring.





48. NOTE: 307-584 and 307-574 are not shown for clarity.

Remove the forward clutch piston return spring snap ring.





49. Remove 307-584/1, 307-584/2, 307-574/1 and 307-574/2.





50. Remove the forward clutch piston return spring.





51. Using a suitable tool, remove and discard the forward clutch piston.





52. NOTE: Note the location of the studbolts for assembly.

Remove the 19 torque converter housing bolts.





53. NOTICE: Carefully pry on the transmission torque converter housing and the case to separate the torque converter housing from the case. Do not pry up on the silicone sealant mating surfaces, damage to the mating surfaces may occur. Carefully lift the torque converter housing off the dowel pins.

Using a suitable tool, carefully pry the torque converter housing off the transmission case just enough to break the seal of the silicone and remove the torque converter housing from the transmission case.





54. Remove the transmission lube tube.





55. Remove the differential and ring gear assembly.





56. Remove the transfer shaft and gear assembly.





57. NOTICE: If a differential bearing is damaged, a new bearing and bearing cup must be installed on both sides of the transfer shaft or excessive noise or transmission failure can occur.

Inspect the differential for damage or excessive wear. Inspect the bearings for excessive wear or damage and inspect the ring gear for damage. Install new bearings or a ring gear on the differential if damage or excessive wear is found. REFER to Differential - Front Wheel Drive (FWD) Differential for FWD (Front Wheel Drive) vehicles or refer to REFER to Differential - All Wheel Drive (AWD) Differential for AWD (All-Wheel Drive) vehicles. If the differential bearings are replaced the bearing races in the transmission case and the torque converter housing must also be replaced. REFER to Transmission Case Transmission Case and REFER to Torque Converter Housing Torque Converter Housing. If the differential ring gear is replaced, the transfer shaft must also be replaced. REFER to Transfer Shaft and Gear Transfer Shaft and Gear.





58. NOTICE: If a transfer shaft bearing is damaged, a new bearing and bearing cup must be installed on both sides of the transfer shaft or excessive noise or transmission failure can occur.

Inspect the transfer shaft for damage or excessive wear. Inspect the bearings for excessive wear or damage and inspect the park pawl wheel, transfer shaft and transfer shaft input gear for damage. Install new bearings, park pawl wheel, transfer shaft or transfer shaft input gear if damage or excessive wear is found. REFER to Transfer Shaft and Gear Transfer Shaft and Gear. If the transfer shaft bearings are replaced the bearing races in the transmission case and the torque converter housing case must also be replaced. REFER to Transmission Case Transmission Case and REFER to Torque Converter Housing Torque Converter Housing. If the transfer shaft is replaced, the differential ring gear must also be replaced. REFER to Differential - Front Wheel Drive (FWD) Differential for FWD (Front Wheel Drive) vehicles or REFER to Differential - All Wheel Drive (AWD) Differential for AWD (All-Wheel Drive) vehicles.

1. Bearings

2. Transfer shaft input gear

3. Transfer shaft

4. Park pawl wheel





59. Remove the pump-to-case seal.





60. Remove the 2 bolts and the oil reservoir.





61. Using a suitable tool, remove the reservoir O-ring seal.





62. NOTICE: Gently pry the pin out of the hole from under the head on each side with a suitable tool or the pin may be broken off in the hole.

Using a suitable tool, remove and discard the TR (Transmission Range) sensor locking pin.





63. Remove the TR (Transmission Range) sensor.

1. Slide the TR (Transmission Range) sensor out of the transmission case.

2. Rotate the TR (Transmission Range) sensor detent plate until it rests against the transmission case.

3. Remove the park pawl actuator rod from the detent lever and remove the TR (Transmission Range) sensor.





64. Remove the park pawl actuator rod.





65. Using a suitable tool, remove the manual lever shaft seal.





66. NOTICE: If the transfer shaft bearing cup is damaged, a new bearing and bearing cup must be installed on both sides of the transfer shaft or excessive noise or transmission failure can occur.

Inspect the transmission case side transfer shaft bearing cup for damage. If the transmission case side transfer shaft bearing cup is damaged, install a new bearing cup. REFER to Transmission Case Transmission Case. If a new bearing cup is installed in the transmission case, install a new transfer shaft bearing cup in the torque converter housing. REFER to Torque Converter Housing Torque Converter Housing. Install new bearings on the transfer shaft. REFER to Transfer Shaft and Gear Transfer Shaft and Gear.





67. Using a suitable tool, remove the halfshaft seal from the transmission case.





68. NOTICE: If the differential bearing cup is damaged, a new bearing and bearing cup must be installed on both sides of the differential or excessive noise or transmission failure can occur.

Inspect the transmission case side differential bearing cup for damage. If the transmission case side differential bearing cup is damaged, install a new bearing cup. REFER to Transmission Case Transmission Case. If a new bearing cup is installed in the transmission case, install a new differential bearing cup in the torque converter housing. REFER to Torque Converter Housing Torque Converter Housing. If a new bearing cup was installed, the differential bearings must also be replaced. REFER to Differential - Front Wheel Drive (FWD) Differential for FWD (Front Wheel Drive) vehicles or REFER to Differential - All Wheel Drive (AWD) Differential for AWD (All-Wheel Drive) vehicles.
