Rated for up to 400 hp, this package is perfect for the mildly modified (tuner, exhaust, cold air intake, etc.) tow vehicle that also doubles as a daily driver. Known for its mild manners on the street, this 48RE is also aggressive enough to efficiently put your Cummins’ power to the ground! This build package features a DPC Reman billet triple-disc torque converter, outstanding Raybestos GPZ clutches, a Raybestos PRO-SERIES intermediate band, billet accumulator piston, billet low/reverse servo piston, a finned deep aluminum pan (and filter extension) and Dynamic’s exclusive custom calibrated HD/Towing valve body (including all solenoids and electronics). This build retains the OEM input shaft, so competition uses are not recommended.

Included with this package is an HD flexplate and DPC Reman billet triple disc torque converter! This is a fantastic torque converter featuring a billet front cover, triple disc clutch, OE-style lockup piston and OE stator, and features a stall speed appx. 250 rpm lower than stock. This makes it a perfect setup to run with an OE input shaft and stock turbo. The torque converter is going to be your largest single improvement in performance. Make sure you have the BEST, and that your valve body is calibrated specifically for YOUR converter!

This transmission package works great for both towing and daily driven vehicles. Featuring our exclusive custom calibrated HD/Towing valve body, you’ll see a significant increase in line pressure and enjoy crisp, quick shifts as well as smooth, controlled torque converter clutch engagements. You get the best of both worlds with this package, without blowing the budget…!!
