I didn't like the way my tranny shifts, looked for a shift kit to install but nothing avalible right now. But found Welcome to B&G Performance "A World Leader in DCX & EURO Tuning Solutions" - Dodge/Jeep/Mini/Bentley Motors/AMG/Mercedes/Ferrari/Porsche PCM/TCM(Computer)Flashes and ordered a tcm computer and it is a night and day difference shifts are harder and power band comes in strong.
