Chevy turbo max 4 banger

The ZF 8 speed is not like that in the slightest. I've never been a fan of Ford's transmissions, they even skip shift in the F150?

In my 2015 with the 6R80 it does not skip shift, but it does like to stay in a higher gear to keep RPM low. Even if I give it a decent amount of throttle it wants to stay in a higher gear. I really should just throw a tune on it to have it hold on to lower gears longer. The sport mode fixes the problem, but at the expense of severe engine braking, which I don’t want in a daily driver.

I think it's just the 10 speed where they do that. GM doesn't, even though mechanically its the same transmission, completely different feeling and tuning on it apparently.

You could try something like a throttle mod which boosts the sensitivity, it is only a "trick" and not a real tune, but the effect is real. Some cars/trucks wake up and feel completely different just because the mid curve "pressure vs response" is no longer gutted.

Your thoughts on these? I’ve been a Toyota fan boy since 2002…Tacomas preferably. Although Toyota quality has gone down hill it seems with TTV6. I maybe looking in to a full size that gets decent gas mileage.

Four banger Turbos I’ve owned…

2008 Cobalt SS Turbo boosted to 18lbs was an animal. Loved it.
0ne exception… my 1986 Porsche 944T boosted to 13 lbs. That was my track car.
Lovely memories

Lack much detail on corporate sales sites......wish GM had torque # at ~2000 rpm

GMC:

• 310 hp [231 kW] @ 5600 rpm
• 430 lb-ft of torque [583 Nm] @ 3000 rpm

Toyota

• 278 hp @ 6000 rpm
• 317 lb-ft @ 1700 rpm

The GM engine also puts out 390 lb-ft by 1500 rpm

Anecdotal, but my friend had major issues with his 2.7 paired with the 10 speed in his Silverado 1500. The tranny would refuse to upshift, and the engine would throw codes with loss of power. This was with only 40,000 miles on the truck. Ultimately ended up dumping the truck and going back to a 5.3 1500 with no issues since. Could have been a lemon, but would make me leery. I know for a fact he is good about his maintenance and not hard on trucks.

2.7s only come with 8 speed. 5.3 come with 10 speed. The older 8Lxx transmissions had issues pre 2022. Allegedly they're 'fixed' now?

I have both a Mopar 8 speed and GM 10 speed. The GM is the smoothest I have ever owned. I hope they stop there - it’s starting to look like a mountain bike competition …
(just focus on reliability) …

Only 3600mi but I really do like this engine.

Maybe someone with more engine knowledge than me can speak up, but I noticed with my Subaru and my Ram, at around the same mileage, the tailpipes were black with soot/carbon already. Tailpipe on the Colorado shows no signs of that.

Does that mean anything notable at all?

Not sure, really.

Could be those engines run richer or something to do with increased HC/oil burning during break in.

Imo, I haven't been a fan of any transmissions in the last 10 years or so. They all seem to stay in higher gears too long so you have low RPM for MPG but no power. I may have to consider tuning my truck to hold onto gears longer.

edit: added "a fan". Helps to have a complete sentence

Thg MG (I realise this isn't a truck, but it has a GM 4 banger turbo) goes to the highest possible gear only when cruising at a steady speed. if I add more than 1kph per second² acelleration, it goes to a lower gear, maybe 2. This keeps it well out of danger from LSPI so I love it. I'm sure the conrod bearings love it aswell, 3k rpm with mild boost vs 1.5k RPM with loads.... and th first 6 gears are really short with the 7th an overdrive, the rpm drop from 5th to 6th is only a fraction of the drop from 6th to 7th.

Inclinations over about 5% and it drops a gear aswell, though there would be plenty of power.

Downside I guess is the official mileage figures aren't stellar, but I beat those on every drive over 3 miles...

it means there could be gasoline particulate filter in the exhaust.

Yes-they do. And they don't do a very good job shifting at all. I traded in an 2020 F150 (only 43,000 miles) with the 3.5 and ten speed. Absolutely wonderful 3.5 motor/ garbage transmission. Went to a 2023 Silverado 5.3 w/the ten speed. So I have had both back to back. It's beyond belief these two transmissions are closely related.
The Silverado has one smooth transmission.

Looking at the Canyon.

2.7L Turbo

27 psi boost??!!???

Cylinder deactivation?? is that true?

I've had my Canyon Elevation 4x4 1 week. Had it out today "trying" to get it in ECO 2 cylinder mode. Finally got it in, but was going 24 MPH on flat ground. Slowly accelerated to 32 MPH before it kicked off. NO AC or it won't work either. So I don't think ECO 2 cylinder mode will be a high priority phase to worry about. I do know it likes 89 octane better then 87 octane. I only use SHELL or Phillips 66 Top Tier fuel.
