This procedure covers removal and replacement of the transmission mount on a 2019-2024 Toyota RAV4 with 2.5L I4 gas engine and FWD transmission.

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. Disconnect negative battery terminal
4. Raise vehicle and support securely on jack stands at manufacturer-specified lift points
5. Remove plastic engine under cover if equipped

Procedure

1. 1

   Locate transmission mount
   The transmission mount is located on the passenger side of the transmission, between the transmission case and the subframe. Identify the mount bracket attached to the transmission and the mounting points on the subframe.
2. 2

   Support transmission
   Position a transmission jack or sturdy adjustable jack stand under the transmission oil pan. Place a wood block between the jack and pan to distribute load and prevent damage. Raise jack just enough to contact the transmission and take slight tension, but do not lift the transmission.
3. 3

   Remove mount-to-subframe bolts
   Locate the two or three bolts securing the transmission mount to the subframe. These are typically 14mm or 17mm bolts accessible from below. Remove these bolts completely and retain for reinstallation.
   Torque spec

   Mounting Bolts61 Nm (45 lb-ft)
4. 4

   Remove mount-to-transmission bolts
   Locate the bolts securing the transmission mount bracket to the transmission case itself. These are typically located on the side of the transmission housing. Remove these bolts while supporting the mount with one hand.

5. 5

   Remove transmission mount assembly
   Carefully lower and remove the transmission mount assembly from between the transmission and subframe. You may need to slightly raise or lower the transmission jack to create clearance. Inspect the removed mount for cracks, separation, or excessive wear in the rubber isolator.
6. 6

   Inspect mounting surfaces
   Clean the mounting surfaces on both the transmission case and subframe. Remove any corrosion, dirt, or old thread locker. Inspect bolt holes and threads for damage.
7. 7

   Position new transmission mount
   Position the new transmission mount assembly between the transmission and subframe. Align the mounting holes with both the transmission case and subframe. You may need to adjust the transmission jack height slightly to align bolt holes properly.
8. 8

   Install mount-to-transmission bolts
   Install the bolts securing the mount bracket to the transmission case. Start all bolts by hand to ensure proper thread engagement. Torque to specification based on bolt size: smaller mounting bolts to 27 Nm (20 lb-ft) or larger mounting bolts to 61 Nm (45 lb-ft).

9. 9

   Install mount-to-subframe bolts
   Install the bolts securing the transmission mount to the subframe. Start all bolts by hand first. Torque to specification based on bolt size: smaller mounting bolts to 27 Nm (20 lb-ft) or larger mounting bolts to 61 Nm (45 lb-ft).

10. 10

    Remove transmission support
    Carefully lower and remove the transmission jack or support stand from under the transmission. Verify that the transmission mount is properly supporting the transmission weight and that there is no unusual sagging or misalignment.

Reassembly

1. Reinstall plastic engine under cover if equipped, torque cover screws to 11 Nm (8 lb-ft)
2. Lower vehicle from jack stands
3. Reconnect negative battery terminal
4. Clear any diagnostic trouble codes if battery was disconnected for extended period

Verification

• Start engine and verify no unusual vibration or movement of the transmission
• With engine running, shift through all gear positions (Park, Reverse, Neutral, Drive) and verify smooth operation with no excessive clunking
• Perform a test drive and verify normal transmission operation with no abnormal vibration, particularly during acceleration
• Recheck all mount bolts for proper torque after test drive
• Inspect mount area for any signs of fluid leaks that may have been disturbed during the procedure
