TREMEC's TKX series 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 TKX 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 it's competitors combined.
