Consumer Description

Had the optional transmission cooler installed at the Honda dealership to help increase vehicle towing capacity. After install, when the vehicle shifts from 7-8 gear at light throttle application (approx. 45mph) the transmission makes a grinding noise. Took vehicle back to dealership and they inspected. They contacted Honda tech support and they stated it is a known design defect. They will not address it in anyway even though there are many possibilities to address this. Noise is energy and energy has to dissipate. I am concerned the grinding noise will start to wear something out and cause a failure later in the life of the transmission or the cooler.
