Low/Reverse Servo Assembly Replacement

Removal Procedure

Danger: To avoid any vehicle damage, serious personal injury or death when major components are removed from the vehicle and the vehicle is supported by a hoist, support the vehicle with jack stands at the opposite end from which the components are being removed and strap the vehicle to the hoist.


1. Raise the vehicle. Support the vehicle.
2. Remove the oil pan and filter. Refer to Automatic Transmission Fluid Filter and Seal Replacement (Service and Repair).
3. Remove the oil feed pipes. Refer to Oil Feed Pipes Replacement (Service and Repair).




4. Remove the three low/reverse band servo cover bolts, the servo and the spring.
5. Disassemble, clean and inspect the low/reverse servo assembly. Refer to Low and Reverse Servo Disassemble (110. Low and Reverse Servo Disassemble).

Installation Procedure

1. Assemble the low/reverse servo. Refer to Low and Reverse Servo Assemble and Installation (111. Low and Reverse Servo Assemble and Installation).





Caution: Refer to Fastener Caution (Fastener Caution).

2. Install the low/reverse band servo cover bolts.

Tighten the bolts to 12 Nm (106 lb in).

3. Install the oil feed pipe. Refer to Oil Feed Pipes Replacement (Service and Repair).
4. Install the oil filter and pan. Refer to Automatic Transmission Fluid Filter and Seal Replacement (Service and Repair).
5. Lower the vehicle.
6. Connect the negative battery cable.
7. Fill the transmission. Refer to Fluid Capacity Specifications (Capacity Specifications).
8. Inspect the transmission fluid level. Refer to Transmission Fluid Level and Condition Check (Transmission Fluid Level and Condition Check).

Note: It is recommended that transmission adaptive pressure (TAP) information be reset.

Resetting the TAP values using a scan tool will erase all learned values in all cells. As a result, The ECM, PCM or TCM will need to relearn TAP values. Transmission performance may be affected as new TAP values are learned.

9. Reset the TAP values. Refer to Transmission Adaptive Functions (Transmission Adaptive Functions).
