Why Some High-performance Transmissions Are Called Dog Boxes

It's yet happened. You person nan chance to thrust your dream car, which, for nan liking of this example, we're saying is simply a 1987 Lamborghini Countach, a car truthful cool that "60 Minutes" erstwhile did an section connected its unhinged testing procedures. Getting successful takes immoderate contortion, but erstwhile you yet get seated, you're greeted by that gorgeous gated shifter. 

This's erstwhile you announcement thing odd. There's a small metallic tab blocking nan first cogwheel slot. As you spell to move nan displacement lever into "first," nan owner, who wisely decided to supervise, slaps your manus and tells you, "That's reverse! First cogwheel is down and to nan left. It's sewage a canine box!" You hadn't noticed nan displacement pattern, embossed connected nan knob.

Ah, yes, nan canine box, aliases arsenic it's besides called, nan dogleg shifter. It's called a dogleg because nan shape going from first to 2nd cogwheel is simply a akin style to a dog's hind leg. Now, cats person nan aforesaid rear limb shape, truthful why settee connected dogs for nan comparison? Probably because group would look astatine you funny if you said your Lamborghini had a "cat box." You'd astir apt get aerial fresheners arsenic gifts for a while.

Dog boxes are communal successful older capacity cars because that's nan shape title car transmissions utilized to use. At least, it was communal backmost erstwhile title cars still mostly utilized manual gearboxes. By putting first cogwheel down and left, this puts nan uber-important 2nd and 3rd gears successful a nonstop line. Second and 3rd are utilized acold much often successful racing, because first is mostly for starting retired and not overmuch aft that.

In a classical section of "Top Gear" — which besides makes those great tunnel tally videos connected YouTube — James May kept accidentally shifting into reverse successful his dogleg-equipped Mercedes 190E 2.3-16. It was apt a goof because, arsenic nan entirety of nan net has pointed out, there's a lockout to forestall accidentally doing precisely that (and an awesome goof it was, emotion you vintage "Top Gear," nary notes). That is besides what that weird tab is successful nan reverse gross connected nan Lamborghini Countach mentioned earlier: a manual reverse lockout to forestall a costly correction erstwhile downshifting.

That's not to opportunity a dogleg shifter would coming zero issues. You could still person musculus representation footwear in, effort to displacement into first, and wonderment why it's taking truthful overmuch effort, only to recognize you've been trying to unit it into reverse arsenic nan postulation ray turns reddish again. It would besides beryllium annoying to effort to prosecute first erstwhile slowing for a tight turn, only to beryllium greeted by an unyielding lockout mechanism. Also, if your car has a manual lockout, that's only arsenic effective arsenic your expertise to retrieve to prosecute it.

Lamborghini switched to a overmuch safer reverse lockout for nan Diablo, specifically to debar accidental cogwheel abrasion/synchronizer dustification. In a Diablo, nan driver has to twist nan cogwheel lever 90 degrees counterclockwise earlier it will spell into nan reverse gate. That's a beautiful improbable mobility erstwhile you're downshifting astir a hairpin.

Oh, nan Mercedes-Benz 300SLR Uhlenhaut Coupe, which erstwhile ferried its namesake technologist Rudolf Uhlenhaut complete 137 miles from Munich to Stuttgart successful conscionable 1 hour. Everything astir it is neat and weird. 

First, this Mercedes is nan astir valuable car successful nan world, having been sold astatine auction for $143 million successful 2022. Its 3.0-liter straight-8 has desmodromic valves for spectacularly precocious revs (F1 driving awesome Juan Manuel Fangio claimed he deed 10,000 rpm). The pedalbox is divided successful two, pinch nan state and brake connected nan right, nan clutch to nan left, and a leather-clad drivetrain passageway successful between. 

The weirdest part, though, has to beryllium nan shifter, which operates for illustration a Bizarro mirror-image dogleg. First cogwheel is up and to nan left, arsenic it would beryllium successful a modular H-pattern transmission. But to displacement into 2nd gear, nan driver has to move diagonally, down and to nan right, arsenic if shifting into third. To move from 2nd to third, nan displacement lever moves consecutive and up. This maintains nan accelerated second-to-third shifts you'd find successful a canine box, conscionable backward. Let's dream nan car's proprietor tin support each this straight, because it's been spotted driving successful Monaco (assuming it's nan existent one).

These days, manual transmissions are unluckily rare, and dogleg shifters rarer. Even stalwart dogleg-using companies started to shape them retired successful nan '90s (Ferrari abandoned nan dogleg 5-speed 348 transmission for an H-pattern successful nan 6-speed F355). The easiest measurement to acclimate yourself to a canine container shape is to get a crippled specified arsenic Assetto Corsa, a decent steering wheel, and a gated shifter for your computer. When mounting up nan shifter, you tin group cardinal bindings for a dogleg shape and believe to your heart's content.
