Bob Rosadini Posted March 4, 2022 Share Posted March 4, 2022 Friend has a 2018 Escalade and he says torque converter is going. It has a 10 speed that is in fact a product of the JV??? What is the difference in this trans when used in a Ford vs a GM? Design was common but manufacturing is by ??Ford or GM? Quote Link to comment Share on other sites More sharing options...

7Mary3 Posted March 4, 2022 Share Posted March 4, 2022 Transmission design is very similar, but the transmissions are manufatured by their respective companies. Programming and case design are the major differences, but due to each company building their own I don't know how many part directly interchange. What is interesting is that Ford's heavy duty 10R140 transmission used in the Super Duty pickups is almost a direct scale-up of the light duty JV 10 speed used by Ford and GM, while GM's heavy duty Allison branded 10 speed used in the Silverado and Sierra is a completely different design. 1 Quote Link to comment Share on other sites More sharing options...

That is because Ford was the lead for the RWD 10 speed and GM designed the 8 or 10 speed FWD transmission. 2 Quote Link to comment Share on other sites More sharing options...
rperez817 Posted March 4, 2022 Share Posted March 4, 2022 (edited) Good information from twintornados and 7Mary3, thank you both! In terms of manufacturing locations for the 10-speed transmissions, they are. GM 10L80 and 10L90 light duty - Romulus Powertrain Plant, Romulus, Michigan GM-Allison 10L1000 heavy duty - Toledo Transmission Plant, Toledo, Ohio Ford 10R60, 10R80, 10R80 Hybrid light duty- Livonia Transmission Plant, Livonia, Michigan and Sharonville Transmission Plant, Sharonville, Ohio Ford 10R140 heavy duty - Sharonville Transmission Plant, Sharonville, Ohio Edited March 4, 2022 by rperez817 1 Quote Link to comment Share on other sites More sharing options...

That is all marketing double speak. GM might have developed to 10L1000 without Ford's "cooperation" but like the 10R140 it's essentially just a scaled-up 10R80.

jpd80 Posted March 4, 2022 Share Posted March 4, 2022 Interesting that Ford didn’t bother developing a 10 speed to go into the F650/F750, they swapped the 7.3 V8 for the 6.8 V10 and called it job done. Quote Link to comment Share on other sites More sharing options...

As some have suggested, maybe that is indicative of the eventual demise of 650/750...sad to say. And the fact that they canceled an air brake option for the 7.3 in 650/750 with some bullshit excuse that underhood temps was the stumbling block speaks volumes to this old truck guy. And when I look at the credentials of this guy heading up "Ford Pro", I'm convinced....Ford thinks "commercial truck" means pick ups and Transits Watch what they talk about next week at the Work Truck Show.

David Ames was asstant chief engineer on the 10L1000, he ought to know. Watch the video around 2:25 and he answers that question. https://www.youtube.com/watch?v=lBocpjvch8M GM originally considered using a version of the 10R140, but very early on decided to go their own way with Allison. If you look at the 2 transmissions side by side you can easily see they are different animals. Really not sure where Next Gear came up with their claim that the 10R140 and 10L1000 are the same. I think they have built a lot of the light duty 10 speed JV transmissions and maybe a few of the 10R140's, and just assumed the 'Allison' 10 speed was the same.

Next Gear is not wrong nor did they say the 10L1000 and 10R140 are the same. If you what pay attention to what David Ames actually says he confirms it. "There was a smaller version of this that was co-developed with Ford. This was done completely separate from it and done with Allison." His first sentence makes it clear the 10L1000 is derived from the 10R80 - only that Ford wasn't directly involved with development of this particular Allison branded derivative of the 10R80. This is the marketing double speak I referred to. Looking at the 2 transmissions side by side you easily see they are fundamentally the same animal i.e. derivatives of a common source/architecture. Next gear came up with their claim based on hands-on experience building and modifying both transmissions. Every company that builds and modifies both transmissions will arrive at the same conclusion because Next Gear's claim is the reality. EDIT: A couple photos to drive this point home. Make note how small the Allison 10L1000 input shaft is versus the Ford 10R140.

JP-Thinking about your post. I remember reading about the new 10 speed and how it was just a few pounds LIGHTER than the old 6 speed. My first thought was..."four more gears and it is almost same weight??...how durable can those be??" No doubt 10 speeds should improve trucks ability to function in ideal RPM band but was it a question of durability once you got into class 6 and 7??? So was it just a better decision to not sacrifice durability and keep the old 6speed in the class 6 and 7 application? Quote Link to comment Share on other sites More sharing options...

Think about it, the 6.7 Powerstroke makes double the torque that the 7.3 puts out, so IMO, the capacity and durability of the 10-speed gearbox was never the limiting factor. Ford just did the minimum amount of change and just swapped 7.3 for 6.8 and called it job done. With regards to a 10-speed auto for Powerstroke F650/F750, I don’t think it was on the table because of what ESP08 showed in his post above, the Big GM box is that much bigger than the 10R140….

Yes but the point I was making that Ford was never interested in putting a 10-speed in the F650/F750, even if it would have worked fine, I assume the Ford and GM gearboxes in the first photo kind of supports that.. (I suspect that the input shaft sizes in the first photo is not the limiting factor). As I demonstrated with the 6.8/7.3 swap, it was all about least changes, as we suspect was the reasoning for other non starter options that Bob mentioned….it was all about avoiding spending money.

It is true that all 3 basic transmissions, the shared light duty 10 speed, 10L1000 and 10R140 do use the same type 4 planet/6 clutch gear trains and utilize clutch to clutch shifting so in that basic regard they are similar (though I think the 10L1000 doesn't use any one-way clutches while the others do). But by that same reasoning you could say the both the C-4 and Turbo 350 are just different versions of the Chrysler 904 Torqflite, 3 speed automatics with 2 planet Simpson gear trains and 2 clutches/2 bands. Looking at everthing else on the 10L1000 I can see far more differences between it and the 10R140 (valve body, cooling, fluid pump, ratios, shift strategy, ect.) than I can between the GM 10L90 and Ford 10R80. Regardless of all that, I did hear from some GM people that they did orignially consider basing their HD 10 speed on the Ford 10R140, but decided not too early in the program. I think you might be reading a bit much into Ames' YouTube comments, as he does state that the 10L1000 was done completely separate from the light duty JV 10 speeds. Sure there are similarities between the two transmissions as they are both modern 10 speed automatics. I have to take what an assistant chief engineer says over what some diesel shop in San Diego says (BTW, they also think the 10R140 is an outgrowth of the 6R140, don't know where they came up with that one because it sure wasn't what I heard). As far was what transmission is better, the 10L1000 or the 10R140, might as well get the ball rolling because I have a feeling that this thread is going in that direction. So far the consensus seems to be that the 10L1000 has a stronger gear train, but I can't substantiate those claims yet. If it is stronger it can't be by much, both transmission's internals look increadibly robust. I will say the GM has having fewer problems with the 10L1000 up to this point, I have seen very few bullitens on it so far. BTW, the aftermarket now has some nice cast aluminum deep oil pans for the Ford 10R140. Can't believe Ford puts a plastic oil pan on those transmissions. Didn't they learn from the plastic oil pans on the early 6.7L Powerstroke? Edited March 6, 2022 by 7Mary3 Quote Link to comment Share on other sites More sharing options...
jpd80 Posted March 6, 2022 Share Posted March 6, 2022 From memory, GM doesn’t use the 10L1000 on the 6500 truck either, preferring a 6-speed auto Alison branded transmission. Quote Link to comment Share on other sites More sharing options...

Guys...again you are all way above my pay grade but 7M, these two pix just completely confuse me; top photo shows two 10 spds- Ford and GM with the GM noted as having smaller input shaft.....rest looks very similar. In the RevMax photo what is referred to as a 10L1000, it looks like a completely different animal that is physically MUCH bigger. Looking at that, no question in my mind as to which has greater capability....."show me the beef" like the old lady used to say in the BK ad! Then again there must be thousands of Ford 10 speeds in service in 450, 550 and now 600. And they are standing up to the torque of the 6.7 I do believe. 7M- you are probably the only poster on this site who is in the real world running a fleet..how about it? By the way I misspoke in my first post...I said the new 10 speed was a few pounds "lighter" than the 6....Actually I had read it was a few pounds "heavier" and my thought was..."4 more gears and it is only a few pounds heavier"? Didn't sound like a good design to me..again on the basis of "show me the beef" I should also add that to me an Allison in a big truck today is a plus....certainly vs my experience 40+ years ago. And I think GM capitalizes on that current heavy truck rep-and as JP noted the 6500 GM uses a true Allison...but the "Allisons" in the GM pick ups and 3500, 4500, 5500 are "Allisons" in name only?

7Mary3 Posted March 6, 2022 Share Posted March 6, 2022 The 10L1000 gear train is pictured next to the much smaller 10R80 light duty transmission in the second photo, not the 10R140 Torq-Shift. Our fleet has purchased very few vehicles since 2019 due to the pandemic and supply issues, so we only have a handful of trucks with the new heavy duty 10 speeds in them. No issues so far that I know about. Neither the Ford F-650/750 or the Silverado 4500/5500/6500 use the new 10 speeds, they still use the 6R140 and Allison 1000/2000/2500 6 speeds respectively. I don't think it's a strength issue in either case, it's just that trucks that size really don't need all the overdrives. Personally, I would like Ford to offer the 7.3L gas engine with the 6R140 in the 250 and 350. I really liked the 6R140. Quote Link to comment Share on other sites More sharing options...

A similar situation with the completely different FWD JV 6,8,9-sped autos developed by GM with Ford opting in on the new 9-speed for 2.0 EB but skipping second gear because EB works better without using it. The other 8-speed autos were developed from the earlier JV 6-speed autos because Ford saw benefit in through developing multiple transmissions using the earlier design as a starting point… Whats abundantly clear is that no matter whether it’s a FWD or RWD JV gearbox, there’s enough development differences inside to need different parts in rebuilds or upgrades.

Dave Rumbaugh Posted March 10 Share Posted March 10 IMHO, as of manufacturing year 2018, the 10 speed longitudinal Ford transmission is a POS. Dropped shifts, skipped gears, hard shifting, floating between gears, and now the bottom 3 speeds have decided to go on vacation. What the hell was wrong with the old 6 speed? Dependable and bullet-proof. Quote Link to comment Share on other sites More sharing options...
