Description
Level 2 48RE transmission with a billet torque converter that has a large single clutch billet piston (#8DX).
Only buy this transmission if you have a diesel close to stock but you want a better than stock transmission.
The 48RE Level 2 Viper transmission comes with all four sets of Alto Red Eagle clutches with Kolene steels plus a direct clutch PowerPack, a Transgo Shift Kit, Sonnax high performance low / reverse servo, Carbon fiber band and a heavy duty intermediate band strut, Sonnax Billet Aluminum 4 Ring Accumulator Piston, Sonnax 16% Oversize Intermediate Servo with Cover and the Power Wedge Intermediate Band Anchor. This transmission (48RE) is good for any type heavy duty / high performance use up to 600 torque, towing, 4WD, high performance and others. Add torque converter upgrade if needed. If you choose a triple clutch diesel torque converter upgrade, we recommend you upgrade to a billet input shaft, otherwise the stock shaft will more than likely break. Also a triple clutch diesel converter will more than likely break a stock flexplate. Please consider upgrading your flexplate if you upgrade to the triple clutch converter.
