Elite 4.9 65 Posted March 8, 2020 Report Share The 5 speed Tremec transmission evolved from Mustang owners needing a transmission that would take the 650 hp , the 302 cid drag engines produced for their 10 second quarter mile racers. The original would only take a couple of runs before second great would blow. When I bought this transmission, they had run 170 passes without a failure. Now called the TKO, this is one tough transmission with a .68 final drive in 5th. Makes for an under 2,000 rpm engine speed @ 60 mph and a top speed, at red line, of over 190 mph.
