Steps

This procedure covers the removal and replacement of the transmission mount on a 2011-2014 Ford F-150 with 5.0L V8 Coyote engine and 4WD.

Warnings

⚠️Vehicle must be securely supported on jack stands. Never work under a vehicle supported only by a floor jack.

⚠️The transmission is extremely heavy. Use a transmission jack or adequately rated floor jack to support it during mount replacement.

⚠Ensure the transmission is properly supported before removing any mount bolts to prevent sudden shifting or dropping.

⚠Inspect all transmission and engine mounts while performing this repair. Replace any mounts showing signs of deterioration, cracking, or fluid contamination.

Parts

Transmission mount (insulator) × 1 — Use OEM specification

Preparation

Park vehicle on a level surface and engage parking brake
Chock the rear wheels
Raise the front of the vehicle and support securely on jack stands at the frame rails
Remove the front skid plate if equipped (save hardware for reinstallation)
Spray penetrating oil on all transmission mount and crossmember fasteners, allow to soak

Procedure

1
Inspect transmission mount
Visually inspect the transmission mount from underneath the vehicle. Look for signs of deterioration, cracking, separation, or fluid contamination. Note the orientation of the mount and any alignment marks for proper reinstallation.
2
Position transmission jack
Position a transmission jack or a floor jack with a wood block under the transmission oil pan. Raise the jack until it just contacts the transmission pan, providing slight support but not lifting the transmission yet. The transmission should still be resting on the mount.
3
Remove crossmember-to-frame bolts
Locate the transmission crossmember bolts that secure the crossmember to the vehicle frame. There are typically multiple bolts on each side. Remove these bolts using a socket and ratchet. Note which bolt locations use which size/length bolts for proper reinstallation.
Torque spec
Crossmember Bolts95 Nm (70 lb-ft)
4
Support and lower crossmember
Carefully raise the transmission jack slightly (approximately 1/2 inch) to take the weight off the crossmember. The crossmember should now be free to move. Carefully lower and remove the crossmember from the vehicle. You may need to wiggle it slightly to clear the transmission mount and exhaust components.
5
Remove transmission mount-to-transmission bolts
With the crossmember removed, locate the bolts securing the transmission mount to the transmission itself. These are typically accessed from below. Remove these bolts completely and set aside.
Torque spec
Transmission Mount Bolts65 Nm (48 lb-ft)
6
Remove old transmission mount
Remove the old transmission mount from the transmission. If the mount is stuck, use a pry bar carefully to separate it from the transmission. Note the orientation and any alignment features for proper installation of the new mount.
7
Install new transmission mount
Position the new transmission mount onto the transmission, ensuring proper alignment with the mounting holes and any locating pins or tabs. Verify the mount is oriented correctly by comparing to the old mount.
8
Install transmission mount-to-transmission bolts
Install the transmission mount-to-transmission bolts and hand-tighten them. Once all bolts are started, torque them to specification in a cross-pattern to ensure even clamping. Note: There are two different torque specifications for transmission mount bolts; verify which applies to your specific bolt locations.
Torque spec
Transmission Mount Bolts65 Nm (48 lb-ft)
9
Position and install crossmember
Carefully raise the crossmember back into position, aligning it with the frame mounting holes and the transmission mount. You may need to use the transmission jack to adjust transmission height for proper alignment. Insert all crossmember-to-frame bolts and hand-tighten.
10
Torque crossmember bolts
Lower the transmission jack slightly to allow the transmission weight to settle onto the new mount. Torque all crossmember-to-frame bolts to specification. Note: There are two different torque specifications for crossmember bolts depending on size and location; verify which applies to each bolt position.
Torque spec
Crossmember Bolts95 Nm (70 lb-ft)
11
Remove transmission jack
Carefully lower and remove the transmission jack from under the vehicle. Verify the transmission is fully supported by the new mount and crossmember assembly.
12
Reinstall skid plate
If a front skid plate was removed, reinstall it using the original hardware. Ensure all fasteners are properly tightened.

Reassembly

Verify all fasteners are torqued to specification
Ensure no tools or parts are left under the vehicle
Double-check that the transmission jack has been removed

Verification

Lower the vehicle and start the engine
With the parking brake engaged, shift through all transmission gears and verify smooth operation
Check for any unusual vibrations or noises that were not present before the repair
Visually inspect the new mount from underneath for proper seating and alignment
Test drive the vehicle and note any vibration during acceleration, deceleration, and gear changes
