Transmission Mount Replacement Guide
Front Transmission Mount
Typical Steps:
- Raise and secure vehicle on lift or jack stands
- Locate the front transmission mount (typically between engine and transmission)
- Place transmission jack or support under transmission
- Remove mounting bolts securing the mount to transmission and frame/crossmember
- Slightly lower transmission to create working space
- Remove old mount
- Install new mount, ensuring correct orientation
- Raise transmission back into position
- Install and torque all mounting bolts to manufacturer specifications
- Remove transmission support
- Lower vehicle and test drive
Rear Transmission Mount
Typical Steps:
- Raise and secure vehicle on lift or jack stands
- Locate rear transmission mount (typically at back of transmission)
- Support transmission with appropriate jack
- Remove crossmember if necessary for access
- Remove mounting bolts securing mount to transmission and frame
- Lower transmission slightly
- Remove old mount
- Install new mount
- Raise transmission back to proper position
- Reinstall mounting bolts and torque to specifications
- Reinstall crossmember if removed
- Remove transmission support
- Lower vehicle and test drive
Side Transmission Mount
Typical Steps:
- Raise and secure vehicle on lift or jack stands
- Locate side transmission mount(s)
- Support transmission with appropriate jack
- Remove mounting bolts connecting mount to frame and transmission
- Shift transmission slightly away from mount
- Remove old mount
- Install new mount
- Realign transmission with mounting points
- Install and torque mounting bolts to specification

Important Notes:
- Always refer to vehicle-specific service manual for exact procedures and torque specifications
- Inspect surrounding components while mount is removed
- Replace all mounts if one is severely worn
- Check transmission fluid level after completion
- Professional installation recommended due to need for specialized tools and lifting equipment
Time required typically ranges from 1-3 hours depending on vehicle make/model and mount location.
Understanding Transmission Mounts
A transmission mount is a crucial component in your vehicle's powertrain system that serves multiple important functions:
What is a Transmission Mount
A transmission mount is a specially designed bracket and rubber/polyurethane component that secures your vehicle's transmission to the frame or subframe of your vehicle. It works in conjunction with engine mounts to provide a stable mounting system for your entire powertrain.
Primary Functions of Transmission Mounts
- Support and Stabilization:Holds the transmission in proper alignment with other drivetrain components
- Vibration Isolation:Absorbs and reduces transmission vibrations from transferring to the vehicle's body
- Noise Reduction:Minimizes noise from transmission operation entering the passenger cabin
- Movement Control:Limits excessive transmission movement during acceleration, braking, and cornering
Types of Transmission Mounts
1. Rubber Transmission Mounts
These are the most common type of transmission mounts, featuring rubber construction that provides excellent vibration dampening and noise isolation. They're ideal for daily driving and comfort-oriented vehicles.
2. Polyurethane Transmission Mounts
These offer firmer support and better durability than rubber mounts. They're popular in performance applications but may transfer more vibration into the cabin.
3. Hydraulic Transmission Mounts
These advanced mounts contain fluid chambers that provide superior vibration dampening. They're commonly found in luxury vehicles and high-end applications.
4. Solid Transmission Mounts
Typically used in racing applications, these provide the most rigid support but transfer the most vibration. They're not recommended for street vehicles.
Signs of a Failing Transmission Mount
- Excessive vibration in the vehicle
- Clunking noises during gear changes
- Visible damage or cracking of the mount
- Transmission movement during acceleration or braking
Regular inspection of your transmission mounts can help prevent more serious transmission issues and maintain optimal vehicle performance.
Common Failure Symptoms of Transmission Mounts: Warning Signs You Shouldn't Ignore
Signs of Transmission Mount Failure & Maintenance Guide
Solid Rubber Transmission Mounts
Signs of Failure:
- Excessive engine/transmission movement
- Increased vibration felt in the cabin
- Clunking or banging sounds when shifting gears
- Visible cracks or splits in the rubber
- Separation of rubber from metal brackets
Service Schedule: Typically should be inspected every 60,000 miles or when symptoms occur. Replacement usually needed between 60,000-100,000 miles depending on driving conditions.
Hydraulic Transmission Mounts
Signs of Failure:
- Fluid leakage from the mount
- Increased engine noise and vibration
- Transmission movement beyond normal range
- Mount feels soft or spongy when pressed
- Vehicle shuddering during acceleration
Service Schedule: Inspection recommended every 40,000 miles. Replacement typically needed between 40,000-80,000 miles due to fluid degradation and seal wear.
Active Transmission Mounts
Signs of Failure:
- Warning light on dashboard
- Electrical connection issues
- Increased vibration at specific RPMs
- Mount not responding to different driving conditions
- Unusual noises from mount area
Service Schedule: Electronic diagnostic check recommended every 30,000 miles. Physical inspection of mount condition every 50,000 miles. Replacement interval varies by manufacturer but typically 60,000-90,000 miles.
Semi-Active Transmission Mounts
Signs of Failure:
- Inconsistent vibration dampening
- Electrical system warnings
- Excessive movement during gear changes
- Fluid leaks (if hydraulic components present)
- Abnormal noise during operation
Service Schedule: System diagnostic check every 40,000 miles. Physical inspection recommended every 50,000 miles. Replacement typically needed between 50,000-80,000 miles.
Note: All service intervals are general guidelines. Actual service needs may vary based on vehicle make, model, driving conditions, and usage patterns. Always consult your vehicle's manual for specific maintenance schedules.
