The WHITELINE KDT928 Positive Shift Kit is a proven bang for your buck modification for the 2011-2015 Mustang GT / V6 / Ecoboost & 2012-2013 Boss is designed to improve shift engagement during dynamic loads. The kit contains a simple yet very effective synthetic elastomer bushing that inserts into the factory transmission mount, reducing the compliance of the heavily voided factory mount. PROBLEM SOLVING - The factory Ford Mustang transmission mount allows for excessive transmission movement due its heavy voiding from the factory. The misalignment of the linkage mechanism causes binding under aggressive shifting and cornering loads. KDT928 effectively fills these voids to reduce the transmission slop for more precise and smoother shifting when you need it most!
