Abandoned History: General Motors' Turbo-Hydramatic Transmissions (Part III)

We return to the Turbo-Hydramatic once more today, and our third installment sees us at a critical point in the timeline of the automatic transmission. Fuel economy pressure from the government and performance demands of the consumer increased considerably in the intervening years since the THM’s debut in 1964. That meant the creation of lighter, more compact, and cheaper versions of the Turbo-Hydramatic compared to its flagship shifter, the THM400. GM branched out into the likes of the THM350, THM250, and the very problematic THM200.

In 1987, GM stepped away from the traditional THM naming scheme and switched to a new combination of letters and numbers. Number of gears, layout, and strength combined to turn the THM400 into the 3L80. But the hefty gearbox was already limited by then to heavier truck applications; passenger cars moved on to four forward gears after the dawn of the Eighties.

  • Ted “the model is going to be almost 4 inches longer and 2 inches wider than its predecessor”Size matters. In this case there is 6” too much.
  • JMII Despite our past experience with Volvo my wife wants an EX30 badly. Small, upscale, minimalist EV hatch is basically her perfect vehicle.
  • Dukeisduke Is the Volvo EX30 even on sale yet? It was pulled from the NACTOY awards because they were having software problems with the vehicle.
  • Wjtinfwb If you've only got 5k to spend on transportation, I cannot imagine a worse way to spend it than on a GM orphan from Sweden that's 15 years old with 150k on the clock and limited plus expensive parts availability and dwindling techs who'd even want to work on it. Go find a similar vintage Camry or Accord with 150k miles or even a Ford or a Chevy, whatever. Hell, even an old Jaguar is less of a crapshoot than a Saab. At least you can still get parts.
  • Kwik_Shift Brands that were considered from China include BYD, Dayun, Great Wall Motors, Maxus, Nio, Omoda/Chery, Seres, XPeng, and Zeekr. KG Mobility from South Korea also made the list of candidates.That's a lot of car companies from there ready to head here.
