Transmission Mount

Replace the transmission mount on a 2017 Maserati Levante 3.0L V6 Twin Turbo RWD to eliminate vibration and restore proper drivetrain alignment.

Warnings

Tools required

Parts

• Transmission mount assembly × 1 — Use OEM specification
• Transmission mount bracket (if damaged) × 1 — Use OEM specification

Preparation

1. Park vehicle on level surface and apply parking brake firmly
2. Place wheel chocks behind rear wheels
3. Raise vehicle on lift or jack and support securely on jack stands at manufacturer-approved lift points
4. Allow exhaust system to cool completely if vehicle was recently driven
5. Inspect transmission mount visually from below for obvious tears, separation, or fluid contamination
6. Verify replacement mount matches original configuration before beginning disassembly

Procedure

1. 1

   Access transmission mount area
   Remove any heat shields or undertray panels that obstruct access to the transmission mount and crossmember. On the Levante, there may be aluminum belly pan sections secured with fasteners. Remove all necessary panels to gain clear access to the transmission mount, which is located toward the rear of the transmission housing where it meets the crossmember.
2. 2

   Position transmission jack
   Position a transmission jack or suitable adjustable jack with a wide wood block directly under the transmission oil pan. Raise the jack until it just makes contact with the transmission, providing support but not lifting the transmission yet. Ensure the jack is stable and centered to prevent the transmission from shifting during mount removal.
   ⚠Do not place jack directly on transmission pan without a protective wood block. Pan damage can result in leaks.
3. 3

   Support transmission weight
   Slowly raise the transmission jack until it takes the weight of the transmission off the mount. Raise only enough to unload the mount (approximately 5-10mm). You should see the rubber mount material relax slightly when properly unloaded. Do not raise the transmission excessively as this can stress other drivetrain components and alignment.
4. 4

   Remove transmission mount-to-crossmember bolts
   Locate the bolts securing the transmission mount to the crossmember below. These are typically two or three bolts accessed from underneath. Use an 18mm socket to remove these bolts completely. Keep these bolts organized as they may differ in length or type.
   ℹ️Some bolts may have thread-locking compound applied from factory. Heat may be required if bolts are seized.

5. 5

   Remove transmission mount-to-transmission bolts
   Locate the bolts securing the top of the transmission mount bracket to the transmission housing. These bolts typically require a 19mm socket and may be accessed from the side or rear of the transmission. Remove all bolts securing the mount bracket to the transmission. Support the mount assembly as you remove the final bolt.

6. 6

   Remove transmission mount assembly
   With all bolts removed, carefully lower and remove the transmission mount assembly. It may be necessary to slightly adjust the transmission jack position to allow clearance for removal. Inspect the mount bracket for cracks, damage, or excessive wear. Examine the crossmember mounting surface for damage or elongated bolt holes.
7. 7

   Compare and prepare new mount
   Place the old mount next to the new mount and verify they are identical in configuration, bolt hole positions, and overall dimensions. Clean the mounting surfaces on both the transmission housing and crossmember using a wire brush and degreaser. Remove any old thread-locking compound from bolt holes in the transmission housing using a thread chaser or appropriate tap.
8. 8

   Install new transmission mount to transmission
   Position the new transmission mount assembly onto the transmission housing. Start all mounting bolts by hand to ensure proper thread engagement. Once all bolts are started, tighten them in a criss-cross pattern to ensure even loading of the mount bracket. Torque the transmission-to-mount bolts to specification using a calibrated torque wrench.

9. 9

   Align and secure mount to crossmember
   Carefully lower the transmission using the jack to align the mount with the crossmember bolt holes. It may be necessary to use a pry bar to fine-tune alignment. Once holes are aligned, start the crossmember-to-mount bolts by hand. Verify the mount is seated properly and sits flush against the crossmember before tightening.
10. 10

    Torque mount-to-crossmember bolts
    Tighten the transmission mount-to-crossmember bolts in an even pattern. Torque these bolts to the specified value using a calibrated torque wrench. After torquing, slowly lower the transmission jack until the full weight of the transmission is resting on the new mount. Verify the mount compresses evenly and the transmission sits at the proper height.

    Remove transmission jack and inspect
    Carefully lower and remove the transmission jack from under the vehicle. Visually inspect the installed mount to ensure it is compressed uniformly and shows no signs of binding or misalignment. Check that all bolts are properly seated and there is no gap between the mount bracket and mounting surfaces.
12. 12

    Reinstall protective panels
    Reinstall any heat shields, undertray panels, or belly pan sections that were removed for access. Ensure all fasteners are properly secured and no tools or parts have been left in the work area.

Reassembly

1. Double-check all bolts are torqued to specification before lowering vehicle
2. Ensure transmission jack and all tools are removed from under vehicle
3. Verify no exhaust components or wiring are pinched or stressed by the new mount installation

Verification

• Lower vehicle to ground and start engine. Check for abnormal vibration at idle with transmission in Park and Neutral
• With engine running, shift through all gear positions while stationary and verify smooth engagement without excessive movement
• Test drive vehicle and verify no drivetrain vibration, clunking, or excessive movement during acceleration and deceleration
• After test drive, raise vehicle and perform final visual inspection of mount to ensure it remains properly seated and shows normal compression
• Check for any fluid leaks around the transmission pan area that may have been disturbed during jack placement
