Are Clutchless Manual Gearboxes Better Than You Think? — Carmudgeon w/ Cammisa & DTS — Ep 232

It’s a transmission episode! Inspired by Jason’s recent roadside spotting of a Volkswagen Karmann Ghia with the rare Automatic Stickshift, the Carmudgeons go for a trip into the origins of abandoning the clutch pedal in manual and automatic transmissions. How has human driving behavior changed or stayed the same throughout history regarding the operation of any transmission? === Visit http://JasonSentMe.com to get a Hagerty Guaranteed Value (TM) collector-car insurance quote! === Jason and Derek begin by discussing the recent repairs on Jason’s (and once Derek’s) Ferrari 308 GT4 - perhaps the only car discussed on today’s episode with a traditional manual transmission. The 308 GT4 just returned from a trip to Aaron Shepherd - one of the most respected auto body specialists in the San Francisco Bay Area - where it received some wonderfully executed rust repair and paintwork. The majority of this episode discusses semi-automatic transmissions throughout history, which begs the question - are any of them any good? Wilson and Cotal Preselector transmissions of the 1930s paved the way for clutchless driving and synchromesh - eventually evolving into applications like Citroen’s Citromatic found in the DS21 and Volkswagen’s Auto Stickshift found in the Beetle and Karmann Ghia. Even after torque converter automatics, clutchless manuals still found their way into road cars - like Mercedes-Benz’s Hydrak Transmission and Ferrari’s Valeo Transmission used in late Mondials. Moving into the 2000s, Jason and Derek remark on how troubled many semi-automatic manuals were at the time - including Ferrari’s F1 gearbox, Maserati DuoSelect, BMW SMG, Toyota SMT, and others which didn’t mind letting a user light a clutch on fire. Luckily - this era was reasonably short-lived, replaced by ZF torque converter automatics and dual clutch transmissions like VW’s DSG and NOT Ford’s horrid SelectShift found in the 2010s Ford Focus, Fiesta, and Escape.
