Anybody have a new GM P/U or Surburban?

[Texasmark]

I was just reading up on the L84 5.3 V8 engine and in the specs it mentioned a 10 speed....I didn't stutter, 10 speed transmission. I was always an advocate of letting the tranny do the work rather than have a muscle engine and a "Powerglide" tranny.

Neighbor has a 6 speed Dodge and he must shift 4 times before he is 100 yards from his driveway. What is it like driving a vehicle with 10 speeds? How does the tranny know what speed to select when you have to do some maneuvering in traffic?

The new Ford 1 ton trucks with the 6.7 diesel have 10 speed transmissions in them. They shift like any old transmission, just a few more shift points. They are smooth and really I don't notice any excessive shifting. After a few times behind the wheel, you don't even notice.

My wife has a Silverado with the 6.2 and 10 speed , you do even feel it shifting.

He must like changing gears running empty going up its rare I use 3rd are 5th.

We had an Expedition with a 10 speed rented on vacation in Yellowstone last fall. The transmision was smooth and it handled the terrain out there quite well.

Don't let the line, "10 speed Allison transmission" fool you. . GM does not use Allison transmissions. They paid Allison for the right to use the name only.

Is the recall on them still on going? They have been known to lock up while driving.

Our 23 F150 has a 10 speed, and we love it!

It was my understanding the 10speed was developed jointly by ford/chevy

Every pickup I buy has two less cylinders than the last truck! I have a 2024 Silverado 1500 with the four cylinder and 8 speed. It works fine. I can count up through about 6 speeds, but I can't feel the last two, but I can see them in the tach. The last two are overdrive. It runs about 1750 RPM at 75 MPH. I just put about 2000 miles on it since Friday. A friend I visit has an older Silverado with the ubiquitous 5.3 V8. He likes driving my truck, as he says it's snappier than his!
I understand those 10 speeds are having troubles.

Really??????

I'm happy with my 2011 Silverado with the 4.8 without AFM and my 4 speed with a "tow" button that ups the shift points if pulling a trailer. I get 50% or so better gas mileage and maybe 30% or better increase in performance over 5 liters I had years ago but I only have 48,000 miles on it, garage kept, having bought it new so mileage isn't even a thought. My owner's manual shows transmission fluid change recommendation is 100k miles for normal driving which I normally do. Any of you know if its the same for 10 speeds?

I guess I'll just hang on to it.Thanks for the replies.

 

[Mule Meat]

Really??????

Not an Allison. Yes it's true. Can only get them in 4500 and larger trucks.

Recall for locking up.. Yes it true.

The recall is on 20-22 pickups using the 10 speed Allison branded (not Allison manufactured or even overseen) transmission. The rear wheels can lock up on a downshift during deceleration. The recall is a software update to monitor the control valve performance and will limit the transmission to 5th gear if excessive wear is detected. I don't have personal experience, this is just what I read. Haven't seen if they issued a warranty extension. I don't even know what warranty is on a GM, Ford or Dodge.

Edit...looks like they do the ever popular 3/36 basic and 5/60 powertrain warranties.

2018 Ford f150 with a 10 speed. Timely question. Mines giving trouble with 76k on it. Just got the repair quote today from Ford. $6500. Have had Ford trucks for more than 50 years. Never a trans problem. After reading appears plenty of issues. Ford and G M are both using the same trans. I will have mine fixed I guess. Really has been a great truck and have liked the trans up til now.

Been driving a 2020 f350 with the 7.3 Godzilla and the ten speed transmission. I really like it. No problems towing or shifting so far. Truck only has 27,000 miles on it though. The Ford ten speed also has a manual feature where you can lock out selected gears. It also has not only the tow/haul mode , but several other options. Seems to be a great improvement to me. I do not notice the extra shifting at all.

i just traded my 2016 gmc 1 ton for a 2020 gmc 1 ton, on avg getting 16.4 mile a gal, about 2 mph better then my 2016. i relly don't notice much.

 

[kenbob]

There is a you tube about them. Ford/Gm basically the same except for some cost cutting tweeks each one took. Gm is way more troublesome in that respect, but it supposedly is a lot smoother in shifts as ford used different solenoids.

We have had a ‘18 Ford Expedition and a ‘23 Chevy Suburban. Both have the 10 speed. IIRC, they are essentially the identical tranny, with only the shift control logic being developed by each manufacturer. And that is where I’ve seen the biggest difference. The Ford shift control logic sometimes makes poor choices (rough shift, incorrect gear, etc). The GM is much improved. I did like that the Ford showed on the dash the actual gear (but most folks likely don’t care). Under light loads, it did a lot of skip shifting (the GM might too, but it’s so smooth, and has no readout, I can’t really tell).

The primary reason for the 10 speeds is to keep the engine in its “sweet spot”, and maximize fuel economy. It’s all about slight improvements to each manufacturer’s CAFE rating. Big $ impact. And that why you don’t see the 10 speed transmission on the 3/4 & 1 tons (those trucks are not part of the CAFE equation).

Good luck!

Ok… I stand corrected… Ford does offer a 10 speed in their SD trucks. At this point though, I’m unconvinced that it is the same 10 speed that is in the 1/2 ton and Expedition.
