Product Details

The OEM transmission mount was designed for ride comfort and is prone to sagging and tearing – above all, it is a detriment to performance.  Its empty voids allow for too much transmission movement, resulting in sloppy handling, numbed responsiveness, and imprecise shifting.  Racecars utilize a solid metal mount to mediate this, which is impractical for street use as it transfers extreme noise and vibration into the cabin.

So how do you achieve the benefits of a solid mount while retaining daily drivability?  FUNCTION-FIRST Performance offers the most effective and easy to install solution.  Our durable urethane rubber insert simply slides in to fill and fortify the empty voids of the OEM mount, preventing premature bushing wear and undesirable transmission movement, all while transmitting minimal added noise and vibration.

The result? Handling is taut and predictable; power delivery is immediate and smooth; gear changes are crisp and confident.

Installation can be completed in about 1-hour.  Pressing out the stock transmission mount bushing is NOT necessary, since the insert halves slide in from either side and are then held in place by the transmission support brackets upon reassembly.

Choose between three hardness levels:

1. SOFT (60A) | Orange - for added performance and to restore and preserve your OEM mount with minimal NVH

2. SPORT (70A) | Yellow - for tuned and sport-oriented performance street cars, with less NVH than TRACK version

3. TRACK (80A) | Black - for optimized performance on track and racecars where NVH is not a consideration
