This procedure covers the removal and replacement of the transmission mount on a 2015-2020 Ford F-150 with 5.0L V8 Coyote engine and rear-wheel drive.

Warnings

Tools required

Parts

• Transmission mount assembly × 1 — Use OEM Ford specification or quality aftermarket

Preparation

1. Park vehicle on level, solid surface and engage parking brake
2. Chock the front wheels to prevent vehicle movement
3. Allow engine and exhaust system to cool completely if recently driven
4. Gather all tools and new transmission mount before starting
5. Raise vehicle using floor jack at manufacturer-designated lift points
6. Secure vehicle on jack stands rated for vehicle weight
7. Visually inspect the transmission mount area and note routing of any nearby components

Procedure

1. 1

   Support the transmission
   Position a transmission jack or sturdy adjustable jack stand under the transmission pan with a block of wood between the jack and pan to distribute load. Raise the jack until it just makes contact with the transmission but is not lifting it. The jack should be ready to support the transmission weight when the mount is removed.
2. 2

   Remove transmission mount-to-crossmember bolts
   Locate the transmission mount where it attaches to the crossmember. Remove the bolts securing the transmission mount to the crossmember. These are typically two or more bolts depending on mount design. Keep these bolts organized as they may differ from other fasteners in this assembly.

   Transmission Mount Bolts65 Nm (48 lb-ft)
3. 3

   Remove transmission mount-to-transmission bolts
   Access the bolts that secure the transmission mount to the transmission housing or extension housing. Remove these mounting bolts completely. You may need to slightly raise or lower the transmission jack to improve access to these bolts.

4. 4

   Raise transmission slightly
   Using the transmission jack, carefully raise the transmission approximately 1-2 inches. This will create clearance between the mount and crossmember. Raise slowly and watch for any interference with driveshaft, exhaust, or electrical components. Do not raise excessively.
5. 5

   Remove old transmission mount
   With the transmission raised, remove the transmission mount assembly from between the transmission and crossmember. You may need to use a pry bar to separate the mount if it is stuck. Inspect the mount for signs of oil contamination, cracking, or separation of the rubber from metal components.
6. 6

   Clean mounting surfaces
   Use a wire brush to clean the mounting surfaces on both the transmission housing and crossmember. Remove any dirt, rust, or old rubber residue. This ensures proper seating and alignment of the new mount.
7. 7

   Install new transmission mount
   Position the new transmission mount between the crossmember and transmission. Align the mounting holes with both the crossmember and transmission. Ensure the mount is oriented correctly with any directional indicators or asymmetric design features properly positioned.
8. 8

   Install transmission-to-mount bolts
   Install the bolts that secure the transmission mount to the transmission housing. Thread all bolts by hand first to ensure proper alignment. Once all bolts are started, tighten them to the specified torque in a cross pattern if multiple bolts are present.

   Transmission Mount Bolts65 Nm (48 lb-ft)
9. 9

   Lower transmission onto mount
   Using the transmission jack, slowly lower the transmission until its full weight is resting on the new mount and the mount is compressed to its normal operating position. Verify the mount is properly seated against both the transmission and crossmember.
10. 10

    Install mount-to-crossmember bolts
    Install the bolts that secure the transmission mount to the crossmember. Start all bolts by hand, then tighten to the specified torque value. Ensure the mount is not twisted or misaligned during this process.

11. 11

    Remove transmission jack
    Carefully lower and remove the transmission jack from under the vehicle. Verify that the transmission remains stable and properly supported by the new mount.

Reassembly

1. Double-check that all transmission mount bolts are torqued to specification
2. Verify no tools or parts were left in the work area
3. Visually confirm the mount is properly seated and aligned
4. Remove jack stands and carefully lower vehicle to ground

Verification

• Start the engine and observe the transmission mount for excessive movement or vibration
• With engine running, shift through all transmission gears and verify smooth operation without unusual clunking
• Test drive the vehicle and confirm no vibration, clunking, or unusual drivetrain noises during acceleration and deceleration
• After test drive, re-inspect all mount bolts for proper torque and check for any fluid leaks around the transmission
• Verify transmission shifter operates smoothly with no binding or misalignment
