V6 3.5L TT 10 speed Xmisson

The ecoboost turbos are also water cooled from what I read. Hopefully Toyota has a secret recipe that works better than theirs.

 

If I was going to bet the farm on a twin turbo v6 half ton with ten speed transmission in 2022+ Toyota would be it.

I guarandamntee you Toyota has benchmarked the living crap out of the turbos, ecoboost engine, and the other 10 spd transmissions and knows the weak points and has designed something that overcomes them.

 

I seen in a video that Toyota had several 3.5EB in house to dissect. Surely they would build something they felt would be better. Early EB would do circles around my 5.7 when towing. Didn't feel like you had to push it hard under load (420tq@2500rpm vs 401tq@3600rpm) . Although I've been in a Toyota since 1983 when my dad bought a new SR5 4wd. Has Toyota ever had an engine that was notorious for unreliability? Maybe the 80/90's 3.0v6....

 

The 3.0V6 for sludge and the 2.0I4/2.4I4 for oil burning are the ones that come to mind for me. They had a turbo Supra with a reliable engine but that motor used a cast iron block.

If I had concerns about the new 3.5TTV6 (or is it a 3.4L) would be the aluminum block and the long timing chain. Ford used one long chain on the early ecoboosts but redesigned it to two smaller chains later. The ford 2.7 eco boost is an iron block but the 3.5 eco boost is an aluminum block. Early 3.5 eco's had a few rod through block incidents and the block was reinforced several years later.

Toyota engineers are smart and have the real world Ford experience to build on so I think the odds are it will be reliable.

 

Just like Ford to reinforce the block to keep the broken rod from protruding.

 

in the old days yes, but not anymore, they have had the best trans on the market for a long time the ZF 8. I had one in my 2013, it was really nice.

mine was actually from Germany at the time since they were right from ZF.

now with all the 10 speeds maybe thats different, but I would buy another ZF8 in heartbeat.

but, Aisin is some of the best transmissions out there, hands down

 

I have a Kia turbo, at nearly 200K, all original minus a couple hoses, there are many other examples on kia user cites, I say if Kia can do it we know darn well Toyo has tested the living shxt out of theirs, they don't take chances on reliability.

I say for anyone above 5-6K elevation, the turbos are a Godsend, especially if you tow. Why did it take us so long to take advantage of turbos?

I also wish they would place the turbos where they belong, away from the engine bay, taking the heat elsewhere and piping the compressed air power back to the engine way, way cooler but it must be too expensive for them to consider. Luck all...

 

Toyota not having tons of data on a new platform yet is still light years better than the data Ford does have. Almost 1 in 5 F150s develop drivetrain issues within an average of 130k miles according to Dashboard Light.

Look at every new generation of every Toyota truck and SUV. Were there any failures or catastrophic issues in the first year? Yes, there was the rust debacle that covered several model years of Tacomas. And before any of you chime in and say the 2016 (3rd gen) Tacoma was a failure, no it was not. People just don’t like that it has a Camry-ish drivetrain in it. Whether we like the drivetrain or not (I personally don’t), it is still a very reliable platform.

I wouldn’t let the newness of the 3rd gen Tundra push you into a reliably problematic F150 (comparatively speaking). Again, Toyota doesn’t release untested tech to their customers; that’s a Ford move.

 

I agree with this, that said, there has been some odd low QDR stuff so far with window seal leaks, check engine lights, etc so far.

my guess is give this till spring or summer and all that will be cleaned up. The 5.7 had some really big things when it first came out as well.

 

It’s not cost, it’s efficiency. The further away the turbo the higher the energy loss. It’s necessary to have the turbine as close to the exhaust as possible to extract the maximum amount of energy. That’s why the Tundra has the exhaust manifold integrated in the cylinder head. And the compressor should be as close to the intake as possible to reduce pressure losses.

 

Yeah water cooling of turbos is nothing new. I’m not aware of any OEM turbocharged engines today that don’t have water cooling for the turbochargers.

I am referring to the exhaust manifold. Unlike the Ford Eco-Boost which has a conventional manifold that bolts onto the outside of the cylinder head over the exhaust runners; the Toyota/Lexus V35A-FTS has the exhaust manifold integrated into the casting of the cylinder head. This arrangement allows the entire exhaust manifold to have a water jacket to control exhaust gas temperatures upstream from the turbochargers.

 

does that also eliminate another part that can leak at the connection? but if you get a crack there, I bet its stupid expensive to replace the entire thing?

 

Yeah if I’m understand the CAD drawing correctly the exhaust manifold being integrated eliminates a fastener and gasket at the exhaust port/runners on the outside of the cylinder head. The turbochargers appear to attach directly to the single exhaust outlet on each head.

Now if that manifold cracks it will ruin the entire head. On the other hand the most likely cause of a cracked exhaust manifold is excess heat and now this design controls that heat with a separate water jacket. So in order to fail you are going to overheat the whole engine, and at that point the heads are gonna get warped anyway.

 

Any towing data in Death Valley?

Remember the old Tundra commercial the killer heat ramp?

 

My 81 Volvo 244GLT had 245k on its original setup when I sold it 15ish years ago.

 

I suppose the whopping 150 horsepower has something to do with it too.

 

Sure didn’t hurt it’s chances. Regardless, Volvo had (very simply) boosted longevity figured out 41 years ago.

Had so much fun with that car in the rain. Probably my best $300 dollar investment to date. LOL

 

The 5.7 has an aluminum block and long timing chains, they're not an issue.

I've had enough turbocharged vehicles to convince me that all the sky is falling stuff on this forum is nonsense. Properly engineered turbochargers last practically forever, I have no doubt Toyota has designed them well. I also appreciate the driving characteristics they give with the power coming in at lower RPM's than a normally aspirated engine, the wide power band makes them a lot more pleasurable to drive.

Aisin makes some of the best transmissions available, I'm absolutely not worried about the new transmission.

 

Lol what? 5.0 doesn’t leak oil and the 10 speed isn’t rough.

You’re going to get the same dead horse answer about reliability. Is the tundra more reliable? Yeah. Does that mean the ford is or others are completely in reliable? No.

 

So with this TTV-6, what is the lowest octane gas it will take? I ask because when I got to Mexico, the gas further south can be questionable. I haven't had a problem, yet, with my 5.7L but I'm curious how the twin turbo handles crappy gas.

 

Should be an Aisin. Almost all the Toyota transmissions are Aisin. They’re solid units.

 

5.0 did consume or burn oil until 2019 or so? Search F150forum.com. That might be something Ford actually fixed. To be fair, Toyota never fixed the cam tower seepage on the 5.7. I would argue it’s not a real issue for the vast majority whose trucks have it as it almost never even leaks enough to drip on the ground. But I digress…

And yeah, there are a ton of threads on the rough shifting Ford 10-speed in 2018s to 2021s. My friend driving this Lunar Rock Tundra behind me in the pic below traded in his new F150 after a year because of this exact issue. Once he finally got the Ford dealer to admit it was extremely rough, they told him, “Sorry they’re all like that,” and wouldn’t do a thing. So, he went to Toyota.

Recent? Check
Specific? Check
Anecdotal? Debatable; I would say not when it matches loads of other people’s experiences.

 

One person transmission Story and they are rough. Mines smooth. Smoother than my LR TRD pro was. Must be better by that logic

 

87 be there lowest I’d run. But me personally when mine comes I’ll run 93 like I do now

 

Glad yours is fine. His story matches all of these…

This.

 

I love em and have had several, but quality they are not.

 

Just get a 21 model, geez

 

When did you become such a big Ford defender?

 

I thought the burning/leaking oil started in 2018 when they switched to plastic oil pans.

Which I guess isn't to say they couldn't have fixed it by 2019 but that's a pretty quick turnaround if they did.
