Borg Warner's extra low ratio Super T10 had a 2.88 first, 1.75 second, 1.33 third and 1:00 fourth. Notice if you plug these gear ratios into the above formula you will end up with the following drops; 39%, 24%, and 25%. The flagship in the Tremec line of aftermarket transmissions is undoubtedly the Magnum 6-speed. This 6-speed is the culmination of years of high performance testing, advanced design changes, and a better understanding of what the aftermarket enthusiast really wants in a high performance transmission.
