Tremec Ford TKO600 Heavy-duty Five Speed Single Overdrive Transmission

We’ve just received a fresh shipment of transmissions

TREMEC’s TKO series (TR3550 family) of 5-speed transmissions was first made famous by the 5-liter Mustang movement and has since been fitted into nearly every rear-wheel drive performance application imaginable. Serving up 600 lb-ft of torque capacity, along with confidence-inspiring shifts and fuel-saving overdrive, the TKO offers an ideal blend of brute strength and street manners – which may be why it’s the manual transmission behind more boulevard-bruising street machines and sportsman race victories than all of its competitors combined.

Based on the 3550 family of five-speed, Tremec up the game in 2004 by offering for the first time TKO600 close-ratio five-speed to replace the “TKO” as the top dog. Close gear ratio with a 2.87:1 first gear for those that have 3.50:1 axle ratio or higher ratios and want the legs to cruise a reduced RPMs, .64:1 (36%) 5th overdrive is the one.  If you are making over big power or play hard in the first for gears and want to cruise home in overdrive the TKO600 is the transmission for you.
