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.

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.

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 GMC Yukon formula is familiar. Big and comfortable with a powerful engine getting things motivated. It’s a winning formula, too – the Yukon is quite popular, as you know.

Underneath, the formula remains the same. Stylistically, though, chances were taken. And that roll of the dice doesn’t pay off quite as well.

GMC had the sense not to mess with the powertrain, but the attempt to keep the styling current is a bit of a messy miss in this application.

Why are we switching to electric cars? I mean, I’m not talking about the need to “do better” when it comes to Mother Earth and the baby kangaroos — even Randy Newman wouldn’t bomb the baby kangaroos — but are EVs and billions spent to lower prices and build chargers for the things really going to make the world better if people just look at them as a way to have their cakes and eat them, too? To put it another way, are you really reducing your carbon footprint behind the wheel of a 9,046 lb. GMC Hummer pickup?

That’s right, kids. The upcoming all-electric Hummer will tip the scales at more than 4.5 tons — and that’s “just” the pickup. The SUV will probably weigh more since it’ll be hauling around more glass, seats, and carpets than the pickup. Despite having enough mass to generate its own gravity, the GMC-badged truck can rocket to 60 mph in under 4 seconds, and effectively crush its way through untouched, virgin wilderness in a manner worthy of its heritage as an Army man cosplay favorite (Punisher window sticker not included).

It’s almost enough to make me throw my hands up and say, “Why bother!?” And that, dear B&B, led me to ask myself the question: What would I drive if I just didn’t give a f***?

If you thought there was an explosion of competitors in segments like the compact luxury crossover game or so-called ‘four-door coupe’ SUVs, it would appear you ain’t seen nothin’ yet. The number of all-electric pickup trucks is piling up like cords of wood, with the latest to show its face being the GMC Sierra Denali.

You finally did it, didn’t you? You beautiful disaster, you did it! You spent nearly $30,000 US American dollars on thirty-seven-year-old Toyota Corolla because of a comic book, and you aren’t even mad about it. Hell, you paid a little extra for the “authentic” Fujiwara Tofu Shop decals on the doors. You. Kick. Rear. And now, after you didn’t think it could be possible to feel better about your automotive purchase, I’m going to make you feel better about your automotive purchase – because you can now buy factory-fresh parts for your Corolla AE86, straight from Toyota.

That’s right kids, through its captive motorsport brand, Gazoo Racing, Toyota is reproducing spare parts for the Corolla Levin Sprinter Trueno “AE86” as part of the GR Heritage Parts Project. The project reproduces new original parts that have been discontinued and sells them as genuine parts with a standard new part warranty, “in order to support customers who wish to continue driving older vehicles that are full of memories and that they truly love.”

All kidding aside, you have to admit that the concept of a Heritage Parts program is great, even if the Initial D AE86 isn’t exactly your cuppa – but it sort of begs the question, what other new-age classics might be worthy of a heritage program? I’m glad you asked!

2020 GMC Sierra 2500 HD AT4

While this news initially surfaced late Friday, we feel it is a significant move by General Motors, one which warrants a bit of discussion even after umpteen different car blogs parroted this news over the weekend.

At issue? The current level of global supply chain disruption, of course. With the only chips in Detroit apparently being of the salt & vinegar kind, car companies have been forced to make some tough decisions – but yoinking heated seats is a very substantial change.

General Motors seems bent on preparing some of its existing facilities as supporting players for future programs. The company has announced a $46 million investment in the metal stamping operation in Parma, Ohio, a town located about 20 minutes south of Cleveland that has nothing to do with the tasty cheese one puts on their pasta.

Today’s Rare Ride coverage was prompted when your author saw an unusual pickup truck on the roads of Cincinnati. The truck in question was a black Sierra Denali from the early 2000s, with a telltale feature on its rear fenders: little lights on either side. Let’s talk Quadrasteer.

GM/ChevroletNinety years. That’s the amount of time that General Motors has led the sales charts in the U.S.

That may change this year, according to industry bible Automotive News, because of the ongoing microchip shortage.

The chip shortage has struck again.

General Motors is going to temporarily halt production at most of its North American assembly plants, starting Monday, because the shortage of semiconductor chips continues.

GMC introduced an interesting concept at Colorado’s Overland Expo Mountain West 2021 this week and the timing couldn’t have been better. While North America has always appreciated off-road vehicles, there’s been an overnight explosion in the number of people considering 4×4 adventuring as a hobby. Troubled times have encouraged individuals to embrace the kind of cars that can tackle any terrain while doubling as a mobile campsite, and the Canyon AT4 OVRLANDX Off-Road Concept certainly seems capable.

Although the hypothetical production model probably has a better chance of becoming canvases for online influences than carrying anybody through a genuine disaster. This is something GMC likewise appears hip to, as the whole point of the concept SUV is to show what can be done with the Canyon, a little creativity, and a wad of cash reserved for aftermarket accessories.  (Read More…)
