Modern Drivelines approach to the C10 Truck using a TKO 5-speed transmission conversion from a 3 or 4-speed manual transmission is quite simple. In most cases, the original Chevy bell housing can be reused along with the 168 tooth 11” clutch pattern or 153 tooth 10.5” clutch pattern flywheel as well as the mechanical clutch linkage. Or we can convert you to a Hydraulic Clutch release as an upgrade. Trucks equipped with automatic transmissions will need a new bell housing, flywheel, and clutch release.

Clutch selection is the next critical step. If your manual transmission is equipped with a 10 spline input shaft, Modern Driveline will select one of our 26-spline, inhouse, handmade clutches matched to your horsepower and use up to 600 Horsepower. Beyond 600 Horsepower or strip use, Modern Driveline will recommend and provide either a Tilton twin disk clutch and Chromoly flywheel or the Mcleod twin disk clutch. If you have an M22 transmission with the “Fine 26 Spline” input shaft, you may be able to reuse your clutch.

 Modern Driveline will reconfigure the TKO and locate the shifter to the “Mid Position”, placing the shifter about 12.3” from the back of the bell housing. With the shifter in the correct location, a  “Hurst” Candy Cane shifter lever will be provided that will work with bench seats and give you that classic look. Once the transmission is mounted to the back of the bell housing, you will use the crossmember provide that will locate the transmission into the correct driveline angle. A slip yoke is included in most conversion packages because in most cases your driveshaft can be shorted at a local shop. Or Modern Driveline can provide you with steel, aluminum, or carbon fiber driveshaft as needed.

Modern Driveline has figured out all the details for C10 conversions for small block, big block, and LS engines.
