Other features include a black console that you can trim to match the contour of your vehicle’s floor, 5-foot long shifter cable, cable brackets, transmission shift levers, chrome plated top plate with lighted gear indicator and everything needed for an easy at home installation. An optional T-handle with a 12-volt button is available separately for actuating a trans-brake, nitrous oxide or other accessories for the hard-core performance enthusiast. This shifter fits most popular Chrysler, Ford and GM 3 and 4-speed automatic transmissions. Note: AOD transmissions require optional kit #40496, GM 4L60E through 4L85E transmissions with PRNDL switch will require optional kit #70499. Overall Dimensions – 14.9L x 6.4W x 14.8H
