Frequently Asked Questions (FAQs)
1. Do transmission mounts affect performance?
Yes, transmission mounts play a crucial role in the performance of a vehicle. A compromised transmission mount can lead to excessive transmission movement, resulting in power loss, decreased acceleration, and reduced fuel efficiency.
2. What do stiffer transmission mounts do?
Stiffer transmission mounts help control the secondary motion of the drivetrain. They improve cornering and enhance responsiveness, especially when encountering mid-corner bumps.
3. What do performance engine mounts do?
Performance engine mounts secure the engine in place and absorb shocks and vibrations during operation. They prevent damage to the engine and improve operator comfort by reducing vibrations and noise.
4. How long do transmission mounts last?
Transmission mounts typically last between 60,000 to 100,000 miles or more. Over time, oxidation and vibrations can cause the rubber or urethane in the mount to fail, as well as the steel bracket.
5. Can a bad transmission mount affect acceleration?
Yes, a broken transmission mount can impact acceleration and cause driveline noise. It may also affect the operation of the clutch or other linkage. However, the rubber material in the mount prevents direct metal-to-metal contact between the engine and body.
6. Do stiffer mounts cause vibration?
Stiffer mounts, such as TUFF MOUNTS, can increase noise, vibration, and harshness (NVH) in the vehicle. This is due to their rigidity compared to standard rubber mounts.
7. Can transmission mounts cause rough idle?
Yes, a broken front engine mount can cause a rough idle and harsh transmission shifts. Replacing the broken mount can help resolve these issues.
8. What type of engine mount is best?
The most commonly used metal for engine mounts is low carbon steel due to its cost-effectiveness and strength. However, aluminum is also a preferred option as it provides higher strength while being lighter in weight, though it comes at a higher cost.
