Whats the deal with the BOSCH CP-ISB21S3 pump?

[Ozymandias]

I still don't get the point, Chrysler builds ZF Transmission by them self.

When I hear fake/real I think a about china copy cats. Not building parts under a license.

So they must have a lot of problems with these 10-speeds if there is such a rumour about it?

The 10-speed is an inhouse GM that Allison is allowing GM to put their name on. It is not a Allison design from what I have read. https://gmauthority.com/blog/2018/12/2020-silverado-hds-allison-transmission-isnt-really-an-allison/

So in the US world of fake things, this Allison is one!

Are there "fake" Allison's?

Sure. Anything smaller than an Allison 3000 is "fake" as far as Allison techs are concerned. The 1000 and 2000 have been an ongoing joke for years.

On my International vehicle build documents, it says Real Allison 2500 Medium Truck Trans.. No Chevy or GM spinoffs.

The one GM puts in their trucks is NOT built by Allison, as it's a "Branded" Allison.

I guess I have a fake Allison and part of a joke... my new MH has the 2500, one of the 2000 series you mention.

Thanks a bunch.

Yes it does, along with detuned engine and nth degree TQ management so it won't hurt itself. The 1000\2000 series units are LD commercial, not a real MD transmission. That is reserved for the Ally 3000 and up units with a reasonable TQ and HP rating. They don't even hold up well behind the V8 diesels without lots of management.

Wrong Again! The motor is not de tuned... it is programmed at a rated HP and TQ, just like the Ram Cummins SO is not a detuned HO, nor is the Cab and Chassis Detuned HO or SO, it is tuned according to it's spec.

And the Allison 2500HS is a proven workhorse...

EDIT: The 2500 series ONLY are offered in medium duty applications and smaller motorhomes. I'm also told the Aisin is heavily TQ managed, I haven't noticed nor have I on the short drive I've made in the Nexus.

Thanks again for nothing.

 

[cerberusiam]

Yep, a whopping 300 HP and 550 input TQ on a MH. Lessee, what are the ratings on the LD trucks again......??????

Of course, lots better than the typical 220\500 the 2000 series was allowed in every MD truck they were used in with a Cummins. Naaahhh, that is not detuned just purpose built. LOL!

Now, if you want something that is real MD the 3000 series at max of 450\+1000 with management is more along the lines fo a real MD trans, suspiciously what a tuned up 5.9 was capable of with little effort. Wonder how long that "workhorse" would last without all the safeties keeping it alive at those levels, hmmm?

With the real Allys capable of handling THOUSANDS of HP and incalculable TQ, no wonder the works "fake" and "baby" are frequently applied by the guys that work on them.

 

[Wiredawg]

Just like the last time we went through this. you show your sarcasm and unprofessionalism. I dont get how you get away with being a super moderator.

EDIT: I'm done with you AND this thread. And dont private conversation me either like you did before.

As I have read all 2021 Rams now have the CP 3 pump installed . I surmise that the failure rate of the CP 4 ( which I and all 19 and20 owners have ) has been a problem that has plagued many owners with repair costs in the thousands per truck . They should recall and pull these time bombs out .

That seems to be untrue as these Trucks are all under warranty so far.

 

[bcbender]

yeah.. its FCA so doubtful they'll actually do anything

The one GM puts in their trucks is NOT built by Allison, as it's a "Branded" Allison.

When generic motors almost ran Allison out of business and had to sell them, they retained the right to call their truck autos 'Allison'

The 10 speed auto in their light duty, class 2a (aka; half-ton) trucks is actually a Ford. Don't know if they're putting it in their HD trucks (like ford is) yet or not. probably

Ford and gm made a deal several years ago that they would work together to build two transmissions; one for rear-wheel drive and one for front wheel drive. Ford got the RWD and built a very, very good ten speed. Still needs some polishing but, overall, a great trans.

generic motors built the FWD trans, A 9 speed that, when presented to Ford, they immediately threw in the trash and came up with their own 8 speed for FWD vehicles.

And the beat goes on

The GM trans is called the 10L80E and the Ford is called 10R80. It was a "joint" venture between GM and Ford to build this transmission.

It is not the transmission used in the HD trucks.

"When generic motors almost ran Allison out of business and had to sell them, they retained the right to call their truck autos 'Allison'"

I think there is more to it.

Ok... Well I learned a lot about Allison and GM corp.... Now, what was I saying in the first place......LOL

There’s one interesting tidbit of information about the 2020 Silverado HD’s hardware you may not have heard yet, though. That new Allison 10-speed isn’t actually made by the familiar Indianapolis-based engineering firm. It will be built in-house by General Motors and simply features Allison branding. The transmission isn’t closely related to the 10-speed automatic found in the 2019 Silverado 1500, as far as we can tell, with General Motors describing the Allison-branded unit as “all-new.”

The only way to get a true Allison-built transmission in your Silverado is to opt for the new Silverado 4500, 5500 and 6500 medium-duty trucks. These monsters will feature an Allison-designed and built six-speed automatic transmission. The new six-speed was developed in conjunction with GM and is designed specifically for use in the gargantuan medium duty Chevys.

It’s not surprising that GM wanted Allison branding on the side of the 2020 Silverado HD. The company is the world’s largest purveyor of automatic transmissions for heavy duty and commercial vehicle applications and has been a mainstay on GM trucks since the 1950s. Chevy’s hard working HD customers have come to know and trust the Allison name and seeing the branding on the side of the truck might give them some reassurance that this new truck isn’t such a departure from older versions of the Silverado HD.

The 2020 Silverado HD will be built at GM’s Flint Assembly plant in Flint, Michigan and will be available in the United States, Canada and Mexico. Pricing has yet to be announced, but stay tuned to GM Authority for more 2020 Silverado HD news and information as it becomes available.
