V6 3.5L TT 10 speed Xmisson

I will be short and to the point.
Anyone have any solid data on the likely long term reliability of the new 3.5L twin turbo V6 and 10 speed transmission in the 2022 Tundra?

I am going to buy a new truck in the next 2 weeks (no choice need a vehicle) and are concerned if both the new engine and transmission will last 250-300k miles.

I know the old 5.7L V8 and six speed transmission were bullet proof and are wondering if thier replacements will be just as good.

 

There is no real data out there, you will be the guinea pig.

 

It was the Pioneers that got the arrows in the back.

 

They also claimed land for free if they made a go of it.

 

I guess they should have paid closer attention to the fine print.

 

The engine has been around for a few years in the Lexus LS500 but that's obviously a different use case. I think the transmission might be new.

The Tundra is still likely going to be the most reliable halfton on the market, though it may have some growing pains. A good second choice would be a GM 5.3 with the 6 or 10 speed or 6.2 with the 10 speed and without the DFM system that they're currently excluding due to the chip shortage.

 

Thanks for the reply, it is as I suspected. Watched a YouTube video with a automotive engineer (David from automotive press) claiming the new 3.5L V6 Twin Turbo was tested in excess of IIRC 2 million closer to 3 million miles and claims the new 3.5L V6 Twin Turbo will last 1 million miles.
For those interested here id the link to the vid.

All I know about Tundra's is based on the 5.7L V8 6 speed transmission. Also I don't know hardly anything about turbo charged gasoline engines other than they IME have been less reliable and do not last as long as their naturally asperated counterparts.

Crap.
Was really hoping for some reliable independent evaluation that would confirm the long term reliability mostly because a similar engine and transmission is in the LS500 but I imagine I was being way to optimistic.

I was really wanting to buy a Tundra as I NEED a 8' bed extended cab truck and only Ford and Tundra make trucks with 8' EX/Cab 1/2 ton pickup's as Ram stopped offering a 8' bed Ex/Cab for 2022 and besides NFW I'd EVER buy a Ram.

Guess I'll have to go with the F-150.

 

Thank for the suggestion, but GM/GMC stopped making an 1500 EX/Cab with a 8' bed back in IRC 2015 and I need to have a 8' bed and I can not afford a 2500 Sierra/Silverado.

 

Serious question here. I’m curious does anyone know of a gas vehicle with turbochargers that the turbos (not just the engine) consistently last in excess of 225k-250k miles? I know diesel turbos often do but they’re built a lot heavier and those engines run at lower RPMs. I asked my buddy who is big into turbo cars, he has a built wrx. He thinks it’s just plain unlikely they make it that far even with modern turbo design from what he has seen. What has Toyota done with their turbos that would enable them to do what no one else has been able to as far as reliability?

 

Guess I'm confused... do you plan to go over 1M miles? I'd say that's damn good confirmation on the new setup's longevity.

 

A “built WRX” probably isn’t the best benchmark for long term reliability.

 

I think you missed the question. I don’t disagree, but the rest of the Subaru engine aside I’m talking about precisely the turbo here. Even the stock Subaru turbos with no tunes or modifications all seem to crap about around 120k miles. I had a legacy GT, and followed several pages and forums regarding that application. Have you regularly seen a turbo on a gas car last longer than approximately 225k miles without an issue?

 

All good points. How have the F150 Ecoboost turbos been holding up? I honestly don’t know myself. I think the new gen turbo motors aren’t like the old ones that showed up in the 80’s. New ones have way better cooling. I guess when I see these questions on forums I can’t help but think, “it’s a Toyota”.

 

Don't know where you're located, Fred Anderson Toyota at Asheville NC had a 2022 SR5 Tundra DC with 8' bed on the lot not sold last week.

 

I definitely think this powertrain will be more reliable than an F150. I don't see any reason not to go with the Tundra if it's down to those two.

The 3.5EB in the F150s has cam phaser problems causing scoring of the cylinder walls. The 5.0 V8s leak oil. Their 10 speed is rough and not at all nice to drive.

 

In fairness, Subaru can’t seem to figure out head gaskets either.

 

“Built” cars vs new engineering (and modern turbo designs) are very different things. The way Toyota engineers their vehicles it should be very common for them to last, especially since for most normal driving people are hardly using the turbos. That is why the trend to downsize engines is so common now. Your friend built a fast car and likely uses it pretty hard. The “engineer” in those videos posted is probably not far off since he has some experience working for Toyota in the past. So I would say, given your options, the new Tundra is likely your best bet.

 

At what point does marketing override engineering when it comes to how many speeds a transmission has? Are 10 speeds really required or is it just keeping up with the other brands?

 

The Turbochargers themselves on V35A-FTS aren’t anything new or unusual. The cylinder heads with internal exhaust manifolds are though. The turbos bolt directly to the head, and the integrated exhaust manifolds have their own dedicated water jackets. So Toyota is making an effort to control the number 1 killer of turbochargers: high exhaust gas temperatures.

 

I had similar questions and decided to do some math.

It's chasing CAFE. The penalty for non-compliance with CAFE is a sliding scale. So both a 10th, or even 100th, of a MPG and showing "good faith" have value in terms of CAFE "compliance."

It's really ludicrous what CAFE spins off in terms of design features. For the life of me I can't figure out what an 8 speed transmission, let alone 10 speed, does for anyone. My Tundra has a 6 speed (you all already know that) and 6th gear is absolutely worthless. Except, perhaps, for "good faith" effort toward CAFE compliance.

 

If you knew where Ford put the water pump you might reconsider that choice. In the 3.5l the water pump is contained in the timing chain housing. This means every 60 to 100k miles you will need to replace that and all the maintenance associated with that.

 

I wish my Tundra was 5-Spd manual or my 2nd choice is 4-spd auto with manual OD. You are right, 6th gear is currently useless. Not sure how 8 or 10 spd will do. Constantly hunting gears?! 6th and higher gears only for rolling downhill when not slippery?

 

I think the idea is that with 10 gears the engine will always be in its peak torque. This will help with towing/hauling.

 

I want my Tundra to have three on the tree!


And get off my lawn!

 

Is the 10 speed made by Aisin? I keep hearing it is a Toyota designed unit but who makes it? Toyota spun out Aisin years ago.

 

It's an option in the Ram heavy duties. They (Aisin) makes some of the best transmissions in the industry. Its one of the reasons I bought a
gen 2.5 Tundra. The Aisin 6 speed is almost bullet proof. Same thing with the 5 speed in my FJ cruiser.

 

LOL . You’ve gone through 3 ZF8 transmissions ? If that’s the case then you’re doing something wrong .
