Are you saying that I MUST remove the entire transmission to replace the transmission mount? Isn't there any way of supporting it and pulling out the four bolts that hold it in place, remove it and then install the new one?

No, i just did not read your question properly, sorry.

 

Transmission Mount Replacement

Important: In order to avoid oil pan damage and possible engine failure, insert a block of wood that spans the width of the oil pan bottom between the oil pan and the jack support.

  1. Use a jack or a utility stand to raise the transmission/transaxle in order to remove the weight from the transmission/transaxle mount and create slight tension in the mount.
  2. Inspect the transmission/transaxle mount. Replace the transmission/transaxle mount if the transmission/transaxle mount exhibits any of the following conditions:
    The rubber surface is covered with cracks.
    The rubber is separated from the metal plate of the mount.
    The rubber is split through the center.
  3. If there is movement between the metal plate of the transmission/transaxle mount and the transmission, tighten the transmission mount fasteners to the correct tightening specification.

 

  1. Raise and support the vehicle. Remove the left front wheel and tire assembly. Remove the left front fender liner.

  2. Install a jackstand and a block of wood to support the transaxle.


  3. Remove the expansion bolt from the transmission mount.


  4. Remove the transmission mount bolts.
  5. Remove the mount.

  1. Transfer the mount bracket to the new mount.


  2. Position the mount and start the bolts into the threads.

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  3. Tighten the mount bolts.

    Tighten
    Tighten the bolts to 66 N·m (41 lb ft).




  4. Install the mount expansion bolt.

    Tighten
    Tighten the bolt to 55 N·m (41 lb ft).




  5. Remove the jackstand and the wood block.
  6. Install the left fender liner. Install the left tire and wheel assembly. Lower the vehicle.
Customer: replied 6 years ago.
Okay, this answers the first part for the transmission mount, what about the motor mounts (the upper front - passenger side; and the dog bone)? I believe there are only these two and they look to be fairly simple...

Engine Mount Replacement

Important: Torque axis mounting systems allow more engine movement than other mounting systems. The engine movement is the design intent of the mounting system. Do not replace the torque axis mounts unless the mount or the rubber is damaged.

  1. Remove the cruise control module mounting nuts.

  2. Remove the A/C low pressure line retaining bracket (1) nut.

  3. Using a block of wood between the floor jack and the oil pan , support the engine.


  4. Remove the engine mount (2) to bracket bolts (1).


  5. Remove the engine mount to body nuts (1).
  6. Remove the engine mount.
  1. Install the engine mount to the vehicle.


  2. Align the engine mount (2) to the mount bracket using a dowel (1).


  3. Hand tighten the engine mount to body nuts (1).

  4. Install the engine mount (2) to bracket bolts (1).

    Tighten

    Tighten the engine mount to body nuts to 66 N·m (49 lb ft).
    Tighten the engine mount to bracket bolts to 130 N·m (96 lb ft) plus 45 degrees.


  5. Install the A/C low pressure line retaining bracket (1) nut.

    Tighten
    Tighten the nut to 10 N·m (89 lb in).

  6. Install the cruise control module. Remove the floor jack
  7. Engine Mount Strut Replacement
    1. Raise and support the vehicle. Remove the right engine splash shield.

    2. Remove the engine mount strut bolts.
    3. Remove the engine mount strut.



    1. Install the engine mount strut.

      Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

    2. Install the engine mount strut bolts.

      Tighten
      Tighten the engine mount strut bolts to 100 N·m (74 lb ft) + 90 degrees.

    3. Install the right engine splash shield. Lower the vehicle.
