This procedure covers removal and replacement of the transmission mount on the 2018-2024 Honda Accord 1.5L Turbo, which supports the transmission and reduces vibration transfer to the chassis.

Warnings

Tools required

Parts

• Transmission mount assembly × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Allow engine to cool completely if recently operated
3. Raise front of vehicle and secure on jack stands at proper lift points
4. Remove engine splash shield if equipped for better access

Procedure

1. 1

   Support the transmission
   Position a transmission jack or floor jack with a wood block under the transmission oil pan. Apply just enough upward pressure to support the transmission weight without lifting it. This prevents the transmission from dropping when the mount is removed.
2. 2

   Remove transmission mount bracket bolts
   Locate the transmission mount on the passenger side of the engine bay. Remove the bolts securing the mount bracket to the transmission case. There are typically 2-3 bolts accessible from above or below depending on configuration.

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

   Remove mount-to-subframe fasteners
   From underneath the vehicle, remove the bolts or through-bolt securing the transmission mount to the subframe or crossmember. You may need to slightly raise or lower the transmission jack to relieve tension on the mount.

4. 4

   Remove transmission mount assembly
   Once all fasteners are removed, extract the transmission mount assembly from the vehicle. Note the orientation and positioning for proper reinstallation. Use a pry bar if necessary to separate the mount from the bracket.
5. 5

   Inspect mounting surfaces
   Clean the mounting surfaces on both the transmission bracket and subframe. Inspect for cracks, damage, or elongated bolt holes. Check the transmission bracket for cracks or deformation. Replace any damaged components.
6. 6

   Install new transmission mount
   Position the new transmission mount into place, ensuring proper orientation matches the original configuration. Align the mount with the transmission bracket and subframe mounting points. Start all fasteners by hand before tightening.
7. 7

   Torque mount-to-subframe fasteners
   Torque the bolts securing the transmission mount to the subframe or crossmember to specification. Ensure the mount is properly seated before final torque. Use a crisscross pattern if multiple bolts are present.

8. 8

   Torque transmission mount bracket bolts
   Torque the bolts securing the mount bracket to the transmission case to specification. Verify the transmission is properly supported by the jack during this step to prevent binding.

9. 9

   Remove transmission support
   Carefully lower and remove the transmission jack or support. The transmission should now rest fully on the new mount. Verify there is no unusual sagging or misalignment.

Reassembly

1. Reinstall engine splash shield if removed
2. Lower vehicle from jack stands
3. Verify all tools and parts have been removed from engine bay

Verification

• Start the engine and verify no unusual vibration or noise from the transmission mount area
• With engine running, shift through all gear positions (P-R-N-D) and confirm smooth operation
• Perform a test drive and listen for any clunking or excessive vibration during acceleration and deceleration
• Visually inspect the mount after test drive to ensure no movement or separation has occurred
