There are millions of these trucks left on the road and guys are building them into slick drivers, drag strip terrors, and pro touring corner burners. The crew at American Powertrain has noticed this and the biggest aftermarket mover of Tremec transmissions has come up with a bolt in solution for your C10 manual transmission needs with their Pro-Fit five and six speed kits. These kits have everything you need to get the transmission in and functional from the back of the block to the front of the differential.
While manual transmission demand in OEM new cars may be waning the enthusiasm for rowing your own gears in a cool old car has not just kept on, it has grown by leaps and bounds.

These kits use the Tremec TKO line of transmissions and American Powertrain has a ton of options to help you with fitment and understanding the best combo for your ride. Ditch the slush box and row your own gears! Here’s how to do it:
