This procedure covers removal and replacement of the rear transmission mount on a 2018-2024 Toyota Camry with 2.5L I4 engine.

Warnings

Tools required

Parts

• Rear transmission mount assembly × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and engage parking brake
2. Place wheel chocks behind rear wheels
3. Allow engine to cool completely if recently driven
4. Raise front of vehicle and support securely on jack stands at manufacturer lift points
5. Remove engine under cover if equipped

Procedure

1. 1

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

   Locate the rear transmission mount
   The rear transmission mount is located at the rear of the transmission, connecting the transmission to the subframe/crossmember. Identify the mount-to-transmission bolts (vertical) and the mount-to-crossmember bolts (horizontal through the mount bracket).
3. 3

   Remove mount-to-crossmember bolts
   Remove the bolts securing the transmission mount to the crossmember. These are typically accessed from below and may be 14mm or 17mm. There are usually 2-3 bolts holding the mount bracket to the crossmember. Support the mount as you remove the last bolt.
4. 4

   Remove mount-to-transmission bolts
   Remove the bolts securing the transmission mount bracket to the transmission housing. These bolts attach vertically through the mount into the transmission case. You may need to slightly raise or lower the transmission jack to access these bolts comfortably.
5. 5

   Remove the transmission mount assembly
   With all bolts removed, carefully remove the transmission mount assembly from the vehicle. Inspect the old mount for cracks, separation, or excessive deterioration. Compare the new mount to the old one to ensure correct replacement part.
6. 6

   Install new transmission mount to transmission
   Position the new transmission mount assembly onto the transmission. Start all mount-to-transmission bolts by hand to ensure proper alignment. Once all bolts are started, tighten them in a cross pattern to the specified torque. Use 75 Nm (55 lb-ft) or 65 Nm (48 lb-ft) depending on bolt size and location per factory specifications.
   Torque spec

   Transmission Mount Bolts65 Nm (48 lb-ft)
7. 7

   Install mount-to-crossmember bolts
   Align the transmission mount bracket with the crossmember mounting points. You may need to use the transmission jack to adjust transmission height for perfect alignment. Start all bolts by hand, then tighten to specification.
   Torque spec

   Crossmember Bolts95 Nm (70 lb-ft)
8. 8

   Remove transmission support and verify
   Carefully lower and remove the transmission jack or support. Visually inspect the mount installation to ensure it is properly seated and all bolts are tight. Rock the transmission gently by hand to verify the mount is secure and there is no excessive movement.

Reassembly

1. Reinstall engine under cover if removed, torque cover bolts to 16 Nm (12 lb-ft)
2. Lower vehicle from jack stands
3. Remove wheel chocks

Verification

• Start the engine and observe the transmission mount for proper load distribution and no excessive movement
• With engine running, shift through all gear positions (foot on brake) and verify no abnormal vibration or clunking
• Test drive vehicle and verify no vibration, noise, or harshness during acceleration and deceleration
• Perform final visual inspection under vehicle to confirm all bolts are secure and mount is properly seated
