Your next race is seven days away. You don’t have time to send the whole unit out.

The AutoGear 2-Speed runs a modular, serviceable cluster — so you can swap ratios between race weekends without rebuilding.

Gun-drilled main shaft keeps rotating weight down and response up.

Built and assembled in Syracuse, NY. → https://autogearsyr.com/products/2-speed/

MUNCIE MONDAY: THE LEGENDARY M22 ROCK CRUSHER 🪨

The most famous Muncie transmission gets its nickname from its signature straight-cut gear whine. But there's so much more to this legend:

-Close-ratio gears: 2.20, 1.64, 1.28, 1.00
-Straight-cut gear teeth for maximum strength
-500+ lb-ft torque capacity
-The soundtrack of 1960s-70s muscle car racing

Love it or hate it, that whine means BUSINESS! 🎵

Every bolt, bearing, seal, and gear in a Muncie four-speed has a part number, and knowing them makes the rebuild a whole lot easier.

Our Manual Transmission Gear Parts guide breaks down the General Motors "Muncie" 4-speed, group by group, starting with the mainshaft and extension housing. Every part is labeled on an exploded diagram so you can identify exactly what you're looking at and exactly what to order.

Whether you're rebuilding a numbers-matching restoration or sourcing parts for a performance build, this is the reference to keep on the bench.

Wondering how much power your M20 can handle? It’s one of our most common questions!

The answer isn’t one-size-fits-all—your transmission’s capabilities depend on many factors: application, upgrades, and how you use your car. That’s why we always recommend getting information direct from the experts.

Thinking about a high-torque build or performance upgrades? Visit our website for in-depth details, or call us to talk directly with our experienced team.

Here’s where 2-speed races are won and lost: the first gear ratio.

Too low and you spin through the corners. Too high and you leave time on the table off the corner. The right ratio depends on the track — its length, banking, and surface — and your rear axle gear.

The AutoGear 2-Speed comes in 15 configurations so you can match the track instead of compromising.

Not sure where to start? That’s what we’re here for. → https://autogearsyr.com/products/2-speed/

Ever look at a AutoGear part number and wonder what all those digits actually mean?

Every Gearbox, Gearbox Kit, and Gearset we build carries a 3-digit Ratio Code that tells you exactly what's inside, plus prefix and suffix codes that spell out input spline, output spline, and whether you're getting a roller 1st gear.

We put it all in one place. Download our free Ratio Codes guide and you'll be able to read a part number like 18-410-332 and know it's a Muncie M22 Gearset before it even shows up on the truck.

Most 2-speeds give you four or five first-gear options and call it a day. Ours gives you 15.

The AutoGear 2-Speed is built for racers who actually tune their setup. Pick the ratio for this weekend’s track, swap it for the next one, and don’t pull the transmission to do it.
15 ratios. 27 or 32 spline. Gun-drilled main shaft. Built in Syracuse, NY.

Congratulations to Andy McDermid WeatherTech Racing #24 on a winning weekend at Road America!

Andy took home wins on both Saturday and Sunday at the WeatherTech Chicago Region SCCA June Sprints, competing in the American Sedan class.

After a challenging start to the weekend, his team made the right repairs and adjustments, came back strong, and put the No. 24 WeatherTech car out front.

Proud to have Andy running with an AutoGear transmission.
