Hemmings Motor News Blog

Hemmings Motor News has been around since 1954. We're proud of our heritage, but we're also more than the Hemmings full of classifieds that your father subscribed to. Aside from new editorial content every month in Hemmings, we have three monthly magazines: Hemmings Muscle Machines, Hemmings Classic Car and Hemmings Sports and Exotic Car.

While our editors traverse the country to find the best content for those magazines, we find other oddities related to the old-car hobby that we really had no place for - until now. With this blog, we're giving you a behind-the-scenes look at what we see and what we do during the course of putting out some of the finest automotive magazines you'll ever read.

Watch This: Shifting a Lenco

If you're into muscle cars, you're into drag racing. If you're into drag racing, you're into weird, purpose-built speed equipment that would confuse mere mortals. And if you can appreciate that kind of stuff, you've at least heard of the legendary "Lenco."

Planetary transmissions have been around for a long time. But that doesn't mean they're any less exotic to most of us. Sure, get all the Hemmings Muscle Machines readers in the same room and most of us have probably heard the word "Lenco" used to refer to just about any planetary gearboxes, but how many of us have actually driven one? Or, at least seen one in action?

Welp, we're here to right such a wrong. Come along with the driver of this fairly woolly '73 Duster and watch him row through sticks on his Lenco. We know this much to be true: For every ten pairs of Levi's 541s atop a pair of New Balance trainers at the drag strip, there's at least one champion planetary gearbox rower.

Now, while we're off shopping hemmings.com for the right car to build around the Lenco we're saving up for, let's hear from you all: How many of you run a planetary in your car?

The Lenco is a series of planetary gear sets, each driving the next, just like an automatic transmission, except the planetary gear sets are locked manually instead of automatically. This video is an excellent description of how planetary gear sets work.
