Transmission Mounts

Transmission mounts locate the transmission to the chassis of the car. Nearly all BMW transmission mounts are made of rubber which is great for absorbing vibrations and noise but may not last very long. Oil from a failing transmission seals will also contribute to premature rubber mount wear. Worn out tranny mounts can lead to harder and imprecise shifting and maybe even a dreaded mis-shift. Rubber trans mounts are generally inexpensive so replacing them every few years will not break the bank. We also offer upgraded stiffer rubber or urethane mounts that last longer and deflect less so the transmission stays in its proper place and the shift linkage is not mis-aligned.

ECS Tuning's Polyurethane Transmission Mounts are designed to address the vital role of transmission mounts in your vehicle's suspension. The factory mounts are notorious for failures that can result in over-revving, mis-shifts, and in extreme cases, potential chassis damage. Our polyurethane mounts provide a robust solution, engineered for both street and track applications, guaranteeing enhanced performance while eliminating concerns about torn mounts.

Polyurethane stands out with its exceptional toughness, durability, and impressive wear resistance compared to rubber. It also exhibits resistance to water, oil, and grease while retaining its original shape even when subjected to significant compression. By reducing deflection, polyurethane facilitates effective power transfer. While there may be a slight increase in NVH (Noise, Vibration, Harshness), the benefits far outweigh this minor compromise in ride comfort. With a polyurethane durometer of 70A, our street mounts are versatile, offering both daily driving comfort and track durability. For more track-oriented enthusiasts, we provide stiffer mounts with an 80A durometer rating.

For a hassle-free installation, we supply a comprehensive DIY guide. ECS Tuning ensures that you are fully supported from start to finish.

Powerflex's new transfer case bushing insert is made from polyurethane and is designed to reinforce your OE rubber transfer case bushing. This helps to stiffen the bushing and limits excessive movement of the transfer case. This Black Series bushing is rated at 95A durometer, which is significantly stiffer than your OE bushing's rubber. This is perfect for someone who tracks their BMW regularly and is looking for the best performance possible without going for a solid mount solution. As this bushing is 95A durometer, a significant amount of extra NVH should be expected.
