The Lenco Transmission has been a staple in the brutal world of motorsports since the 1970s. The design has been refined some over the years but the basic mechanical principle remains the same. A series of stacked planetary gear sets get engaged by levers or air as the car accelerates. Contrary to popular belief, these transmissions can be driven on the street. They were hugely popular in the world of pro stock for a couple of decades and they continue to be ever popular in classes like Pro Modified.
Racers love them for many reasons but the fact that they are easily rebuilt, very strong, and can be altered in terms of gear ratio easily make ’em perfect for the brutality of the drag strip. In this video we see a Lenco get rebuilt after spending time in a heavy, 2,500hp car.
Parts are time lapse, parts have music, but we think this is a cool look into the transmission and into how one gets serviced when it is time for a full freshen up job. Check out the video and let us know what you think below!
