*Note-TREMEC T56 Magnum transmissions can be shifted from two different locations - mid and rear. From the factory they are configured as a rear shift. To change the location, you must purchase a mid shift kit (sold separately). The rear shifter location is then capped off with a plate provided in the kit.
