The U.S. National Highway Traffic Safety Administration (NHTSA) has listed its’ automotive recalls for June 2 through 9 and the list includes Audi, Chevrolet, Ford, GMC, and Honda vehicles for various types of recalls.

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.

Our Abandoned History coverage of the Turbo-Hydramatic transmission series continues today. The THM was a singular solution to two different automatic transmissions in use by Oldsmobile, Cadillac, and Buick in 1963. Turbo-Hydramatic arrived at a time of modernization for the automatic, which prior to the mid-Sixties was regarded as inefficient and less than smooth.

The THM400 was the 1964 replacement for the Hydra-Matic and Buick’s Dynaflow and established itself as a smooth and reliable gearbox. It proved useful in a variety of luxury and heavy-duty applications and shrugged off weight and torque easily. In short order, it took off as the transmission of choice for various small manufacturers outside of GM. However, no matter how excellent the THM400 was, it found itself squeezed by a drive toward greater fuel efficiency. It was also a bit hefty to be of broad use in smaller or lighter passenger cars. GM needed more Turbo-Hydramatics!

A few weeks ago, we concluded Abandoned History’s two-part coverage of the Chrysler UltraDrive transmission. Within the comments was a request for more transmission coverage of an equally abandoned nature. Let it be so! Come along as we discuss the vast automatically shifted expanse that was the Turbo-Hydramatic transmission family, by General Motors.

Following an abundance of rumor and conjecture (plus a bit of trying to wring the grapevine for news), top brass at General Motors have confirmed an electrified Corvette will prowl the streets and tracks of America as soon as next year. Even more interesting? An all-electric Corvette, based on The General’s new Ultium EV architecture, will also show up in due course.

On Monday, General Motors’ added a second shift for Heavy Duty variants of the Chevrolet Silverado at Oshawa Assembly to ensure the automaker can meet demand. There are also plans to launch a third shift to spur production of light-duty pickups after GM spent the last two years struggling to deliver vehicles in a timely manner.

GM Canada recently representatives from the Canadian federal government, eager to show that its $2 billion investment into Ontario manufacturing (specifically at Oshawa and CAMI Assembly) had already borne fruit. While this is said to eventually include the production of BrightDrop’s all-electric and perpetually connected Zevo vans, GM is presently focused on swelling production on some of its most valuable products.

While the market is awash with crossovers and SUVs, not all of them make the cut. According to the crew at GM Authority, General Motors is planning to axe the Buick Encore and Chevrolet Trax after the 2022 model year.

Just about every automaker has committed itself to going “all-electric” at some point in the next decade, and whether you think that’s a good thing or a bad thing, it means that the internal combustion engine (“ICE”, for the purposes of this article) is dead tech walking. Death and discontinuation are usually one-way tickets to the scrap heap for cars – but some cars are different. Some cars are special, and being made rare or obsolete just makes them more appealing.

The Great Jack Baruth once called this The Grand National Problem, and I think there are a few ICE cars out there that will be more appealing to car guys and gals than others in 20- or 30-years’ time. As such, I’ve taken some time to look at the automotive class of 2022 and pick my 5 future ICE Age Classics. Enjoy!

GM is set to introduce more EVs to its fleet, announcing this morning that it will be stuffing a Blazer full of electrons and putting it on sale next year. Touted as the “first Chevy EV to feature a performance SS model”, GM says the all-electric Blazer SS will make its debut later this year and will be available in spring 2023.

With this news, we’ll sit back and wait for the B&B to discuss GM’s continued propensity to apply the SS badge in weird and wonderful ways.

Chalk up another victim of the ongoing global supply chain headaches. GM announced to its dealers this morning, by way of its fleet order guide, that their large SUVs – 2022 Tahoe, Yukon, et al – will not be offered with a rear-seat entertainment system “for the model year.” This marks just one of many features which have vanished from vehicles in the wake of what’s been a tough couple of years for carmakers.

Proving the situation is fluid, some items are creeping back into rotation. For example, heated seats are once again part and parcel of the Chevy Traverse – just in time for summer.

We return to the saga of GM’s High Technology engine today, after taking a diesel detour in our last entry. Concurrent in the High Technology engine’s timeline, the Oldsmobile diesel’s failure was quick, but certainly not painless. It put the majority of American consumers off the idea of a passenger car equipped with a diesel engine. And by the time GM pulled the diesel from its various brand lineups, there was a strategy change over in HT4100 land: Not calling the engine HT anymore.

The midcycle refresh is a tool that has been used by carmakers for eons, giving them the opportunity to inject new interest into a machine that’s been on the market for a few years. Chevrolet has taken this step with the 2023 Blazer and, in the process, made it a great candidate for those old Spot The Difference games which used to appear in the Sunday paper.

In today’s edition of Abandoned History, we return once more to the late Seventies engines of General Motors. After the disaster which was the V8-6-4 and the subsequent release of the quite flawed HT4100 V8, we take a sidestep today into diesel. Time for a turn with the cost-cut cast iron Oldsmobile oil burner that accompanied the troubled gasoline engines at GM dealerships across the country.

The all-electric Chevy Bolt has had a rough go over the last year, falling victim to battery troubles which led General Motors to halt production and recall every single copy they’ve ever built so they could stuff the things full of new electrons because of a fire risk.

Alert readers will know those recalled battery packs are different than GM’s own Ultium product, tech that’s finding its way into all forward-looking EVs from The General. This makes the Bolt something of an outlier and, after hearing remarks from Mary Barra in this week’s GM earnings call, probably a dead car walking.
