re: As of Dec 31, 2025 Allison and GM are divorcing.

Well, the Aisin was always great behind the Cummins other than a brief manufacturing snafu. The ZF 8 speed they have now is spectacular but of course, they fricked up the engine post-2018 and what you get now is not worth the premium price they charge.

Pre-2018, you got (for the most part) a commercial cummins ISB6.7 school bus / garbage truck engine in the pickups. Solid lifters, CP3 fuel pump, cast iron everything. A heavy, noisy, dead nuts reliable engine. This was how Ram kept the cost of a diesel pickup comparatively low to Ford and GM for decades and developed a reputation for a piece of shite truck wrapped around the best engine. All of the RFE transmissions were shite heaps behind the diesel and require loads of torque management to live even a brief life of hard work which makes the truck feel like a complete turd compared to a ford or GM diesel.

Post 2018, because the old engine was too noisy, the engine turned into a hydraulic lifter GCI block CP4 fuel pump heap of shite. For a while there you could get a heap of shite engine with a heap of shite transmission behind it in a HD pickup truck for a $13k premium over a gas burner. Cool!

A 2014 to 2018 cummins (the best diesel ever put in a pickup truck) engine with the new ZF8 transmission would be the best driveline ever put in a pickup truck but alas, that would be too good of a good thing and would never exist.

Amazing how many folks don't realize what they own. They just trust the badges.

serious question, how are you supposed to figure this out? If the badge is on the vehicle, is the physical part also not branded as allison?

I am not flaming you here, it's a legit question.
Thanks

my friend who has a 23 tundra just had the engine blow up on him at 23k miles. his vin didnt fall under the recall. toyota still fixed it for free though.

You don't without some serious detective work, and it ultimately doesn't matter anyway. The builder/supplier relationships are super difficult for the average dude to decipher when it comes to passenger vehicles because everything is so minutely specialized to mass production that virtually no components are off the shelf items.

IE you can buy a Cummins-powered ram truck, but the engine in that truck is so specialized to that particular truck that just about the only thing it has in common with the rest of Cummins' product catalog is the name. Now that's probably the least true for the Cummins engine relative to all of the other components in a vehicle but you get the idea. The primes (GM, Ford, etc) have so much direct involvement in the design of the major components that it doesn't really matter what brand product it is or what their reliability / value / etc really are in other markets, you're getting a product of the company who's badge is on the grille and that's all that really matters to the end buyer.

There's no use in nerding out what will last the longest or what has the most power or whatever it is. It's a hunk of metal to haul your arse and your stuff from point A to point B and the manufactures have succeeded in masking every pertinent piece of information there is on how much money it will cost you to do that for 20 years with a given vehicle.

So, just buy what you like, drive it till you don't like it anymore, then get something else. No matter how much someone prides themselves on researching shite to the Nth degree and figuring out every detail and patting themselves on the back for making some genius vehicle purchase, they really didn't. Reliability and repair data is the second most closely guarded secret a vehicle company keeps, and you really don't know shite no matter how hard you worry about it, so don't bother.

I'd really love to see Allison design a HD transmission for Ram Trucks with Cummins engines.

Could you imagine the people that would be demanding Toyota take their money if a good Cummins was mated to a good Allison Transmission in a Toyota 3/4 and one ton? Huuuuge potential. Toyota would end Ford, GM, and Dodge heavy duty trucks.

They are available now with the ZF 8 speed. It’s a really good transmission.

It's more of a Ford designed product.

It's a ZF 8 speed with an added intermediate clutch set and Ford and GM make their own versions with their respective tweaks. GM homers don't get to blame Ford on this any more than Ford can blame ZF.

What the hell could there possibly be 50 of on a new vehicle that needs a subscription? Do you need a subscription to check the tire pressure?

With all of the insane bullshite that car manufacturers are putting into vehicles now, why not just keep driving older vehicles. Saw an article yesterday that Stellantis vehicles are now using the infotainment system to advertise new vehicles

I'll stick with those as long as I can. There is literally no benefit to having your car connected to the web.
