Up next Study Finds That Fuel Costs of EV’s Overtake Those Of Gas-Powered Cars Published on February 06, 2023 Author Mike McGlothlin Tags #trans, #valvebody, 68rfe, transmission, Share article Facebook 0 Twitter 0 Mail 0 World’s First Full-Manual Valvebody, Four-Speed 68RFE Full-Manual Valvebody, Four-Speed 68RFE WP Developments has created the world’s first full-manual valvebody 68RFE. The quick-shifting four-speed does away with the use of the 68RFE’s first gear (where sprag failure is highly common) and fifth gear (where 4C clutch failure is frequent). Lockup is available on command via button as is Overdrive, and the valvebody is SSV-less—meaning no more bore/end plugs leaking. This setup will save you thousands over a 48RE swap—not to mention the headache that goes along with it, namely in trying to make everything work like factory.
