Automatic Transmission Assembly

Removal & Installation

To Remove:

NOTE: If the transmission will be removed for an extended period of time, make sure to support the engine with a safety stand and a wood block.

1. Disconnect the negative battery cable.
2. Put the vehicle in NEUTRAL then raise and safely support the vehicle.
3. If it is necessary to disassemble the transmission, drain the transmission fluid.
4. In 4x4 vehicles ONLY: Remove the transfer case.
5. To keep the driveshaft balance the same, draw marks on the driveshaft yoke and axle flange to ensure they can be installed with their original alignment.
6. Remove the bolts on the rear driveshaft then remove the rear driveshaft.
7. Remove the Starter Motor.
8. Remove the torque converter access cover.

   NOTE: Mark the torque converter and flexplate to ensure correct alignment at installation.

9. Rotate the flexplate to access the nuts then remove and discard the converter nuts.
10. Disconnect the shift cable from the bracket and from the manual control lever.
11. Remove the transmission wiring harness, disconnect the heated oxygen sensor (HO2S) connector, the transmission connector, the output shaft speed (OSS) sensor, and the digital transmission range (TR) sensor connector.
12. Remove the three way catalytic converter.

    CAUTION
    Be very careful to not damage or bend the cooler lines.

13. Hold the case fitting and remove the transmission cooler lines.
14. Remove the nuts.

    CAUTION
    Do not let the transmission hang freely.

15. Place a High-Lift Transmission Jack under the transmission. Safely raise and support the transmission.
16. Remove the crossmember by removing the bolts on each side.
17. Remove the transmission mount and screws.
18. Remove the transmission upper fill tube.

19. Lower a High-Lift Transmission Jack to get access to the screws to remove them.
20. On 4x4 vehicles ONLY: Remove the vent tube assembly.

    WARNING
    The torque converter is heavy and can cause injury if it falls out of the transmission. Make sure the torque converter is secured in the transmission. Failure to do this can cause personal injury and/or damage to the vehicle.

21. Install the torque converter retainer (307-346) before lowering the transmission from the vehicle.

    WARNING
    Make sure to secure the transmission to the transmission jack with a safety chain. Failure to do this can cause personal injury and/or damage to the vehicle.

22. Safely lower the transmission.
23. If the transmission is being overhauled or if a new or remanufactured transmission is being installed, perform transmission fluid cooler backflushing and cleaning.

To Install:

1. On 4x4 vehicles ONLY: Install the vent tube assembly.

   WARNING
   Make sure to secure the transmission to the transmission jack with a safety chain. Failure to do this can cause personal injury and/or damage to the vehicle.

2. Safely raise and position the transmission.
3. Remove the torque converter retainer (307-346).
4. Using the marks made during removal, align the flexplate to the converter and install the transmission-to-engine screws as indicated below:
   • Step 1: Install 1 M10 x 1.6 in (40 mm) screws. Torque to 35 ft-lb (48 Nm).
   • Step 2: Install 4 M10 x 2 in (50 mm) screws. Torque to 35 ft-lb (48 Nm).
   • Step 3: Install 2 M10 x 3 in (75 mm) screws. Torque to 35 ft-lb (48 Nm).

   Transmission-to-engine screw types

5. First install the upper fluid filler tube as shown in the diagram below. Next, install the M10 x 1.6 in (40 mm) bracket screw and torque to 35 ft-lb (48 Nm).

6. If present, install the transfer case.
7. Install the exhaust bracket and screws. Torque to 73 ft-lb (99 Nm).
8. Position the crossmember and install the bolts. Torque to 74 ft-lb (101 Nm).
9. Install the transmission mount into the crossmember and tighten the nuts. Torque to 73 ft-lb (99 Nm).
10. Remove the High-Lift Transmission Jack.

    CAUTION
    Be careful to not damage or bend the cooler lines.

11. Hold the case fitting and install the transmission cooler lines. Torque to 19 ft-lb (28 Nm).
12. Install the new torque converter nuts. Torque to 26 ft-lb (35 Nm). To get access to all the nuts, rotate the crankshaft as needed.
13. Install the starter motor.
14. Install the catalytic converter assembly.
15. Install the transmission wiring harnesses. Connect the following parts: the heated oxygen sensor (HO2S) connector, the transmission connector, the output shaft speed sensor (OSS) connector, and the digital transmission range (TR) sensor connector.
16. To install the shift cable, connect the shift cable to the manual control lever, and then connect the shift cable to the bracket.

    NOTE: Line up the driveshaft yoke and the axle shaft marks you made during removal.

17. To install the rear driveshaft, position the driveshaft then install the 4 bolts. Torque the bolts to 83 ft-lb (112 Nm).
18. Prior to lowering the vehicle, observe the following guidelines for installing the in-line transmission fluid filter.
    • If the transmission has been overhauled and the vehicle was equipped with an in-line fluid filter, install a new in-line fluid filter.
    • If the transmission has been overhauled and the vehicle was not equipped with an in-line fluid filter, install a new in-line fluid filter kit.
    • If the transmission is being installed for a non-internal repair, do not install an in-line filter or filter kit.
    • If installing a new Ford-authorized remanufactured transmission, install the in-line transmission fluid filter that is supplied.
19. Safely lower the vehicle.
20. Connect the negative battery cable.
