Making horsepower is fun, but it’s worthless if you cannot effectively send that power to the tires, and TSI’s transmission lineup makes it easier than ever! Have a hot street car that needs the 4L80E’s overdrive to chew up longer trips? We’ve got you covered. Or do you have a bonafide race car making four-digit horsepower numbers that needs an SFI-certified gearbox? If that’s the case, our Powerglide and TH400 options are just what the doctor ordered.
