A clever transmission gear diagram tee that speaks fluent trucker, perfect for anyone who knows what part of the rig you're talking about.
The story behind this design
This design takes the visual language of a vehicle transmission schematic and repurposes it into a humorous message. The upper half shows a Hi-Lo gear box with positions labeled in mechanical notation; the lower half mirrors the layout with a neutral position marked. The framing text asks a tongue-in-cheek question that only makes sense to people who live and breathe trucks—it's an inside joke rendered in bold, technical typography. The stark black-and-white aesthetic feels authentic, like something you'd see on a diagram in a truck cab, while the humor keeps it light and wearable for everyday use.
Who it's for
Ideal for truck drivers, mechanics, fleet workers, and anyone deep in the trucking or heavy equipment world. The design's wit makes it great for coworkers, especially as a gift between people who share the same professional language. Fits casual wear for anyone who wants to display pride in a skilled trade or signal their place in an industry community.
