I'm looking at used trucks.
After 4 yesrs of production on the 7.3.
Is the 6.2 still considered more reliable than the 7.3?
Here in Canada there's very few 2020-22 ,7.3s on the used market. tons of 6.2s.
Should I avoid the first 2 years of the 10 speed anyway?

 

late model years 6.2 is good to go, I would choose them over the first few years of 7.3. the 6.2/6 speed combo is what I would look for.

 

In the 2016 and older Super Duty, the 6.2L/6R140 was a very reliable powertrain.

 

And the 2017+ ones got a power bump.

OP, for 2017-19, the 6.2L in the F250 got the 6R100 transmission, while the F350 got the beefier 6R140. Both were reliable.

 

Short answer yes, the 6.2L at this point is still the more reliable option.

Long answer you're comparing a 12 year engine run to a 5 year engine run. Both versions (2011-2016 and 2017-2022) of the 6.2L have been plenty reliable with the latter suffering from IMRC failure but its still 100% drivable and not something that's a rush to fix. The 7.3L in the early years had some growing pains like #2 spark plug wire and crank shaft seal leaking and there are reported premature failures due to lifters/cam. 7.3L was revised for 2023 but still new enough that reliability cant be gauged yet.

Assuming you're just looking at 2017-2022 used models here is the transmission breakdown for the 6.2L.
2017-2022 F250 mated to 6R100 transmission. (hardly any reports of being unreliable)
2017-2019 F350 mated to 6R140 transmission. (hardly any reports of being unreliable)
2020-2022 F350 mated to 10R140 transmission. (growing pains in those years, CDF drum, valve body, plenty of clunky shifting reports some of which fixed with software reflash others not).

Overall go read the 6.2l and 7.3l forum and youll get an idea of the issues owners are reporting.

 

Both good. Just do a general check of the vehicle and check the engine hours.

 

I had a 17 6.2 for 5 years and 60K. Lost a valve spring at 12K. Otherwise fine. Is that reliable or not? No idea. Stuff happens. Tranny was a 6R140 and was flawless but not enough gears when towing imo since the 6.2 needs to rev. Now I have a 22 7.3 with 27k. No problems at all with a negligible loss in mpgs from the 6.2. The increase in power is very noticeable. 10R140 is perfect imo. Love the truck and combo. Perfect for my use. No way would I even consider a 6.2 at this point.

I have a couple 7.3's in 2021 550's that haul 12K mini excavators and plow and sand in the winter. We beat the crap out of them. 25K miles and going strong (lots of short trips). Both have had plug wire issues common to that year. Crew likes them a lot. That said I have a 20 and 21 F350's with 6.2's with 10R140's. They are fine as support rigs but we don't tow with them often. The 20 has had a couple ECM glitches with the tranny. The 21 has never been to the shop other than oil changes. my 2 cents.

 

Minor issues on either, I would pick the one with the best maint history.

 

Interesting question. The 7.3 and 6.2 are the only engines ford offered that are worth owning IMO, both are excellent. Maybe after another 5 years, another engine will be added to the list...........but, I doubt it.

 

the 6.2 is no longer offered. As far as recent motors, the 6.8 V10 was a good one too.

 

On the 7.3, I just found out today. My friend's 2020 7.3 lost the motor at 85k miles. Loud ticking suspected valve train failure. doesn't make me feel very good.
The only guy I know with one had his fail.
We still don't have a good idea of the actual failure rate though

The 6.8 v10 hasn't been in a truck since 2010?
that's getting pretty old.
The shop I work at has a 2010 with the v10.
It lost the intake butterfly through the motor at 160k miles. It really beat up the motor. We rebuilt it.

 

it was available in classic cabs, vans and RVs until 2019. They were pretty good toward the end.

 

You probably should post what its going to be used for. What trim level you want etc.

You are getting suggestions for the 6.8 V10 which as mentioned was only in the C&C recently.


Some people on here think the gassers are the end all be all and run out and buy a Lariat gas job to tow their RV over the mountains.

 

And there's a problem with that?

 

I've owned three 6.2/6 speeds. Now on my third 7.3/10 speed. I don't miss the screaming engine while towing through mountains or hilly country. And that wasn't even a super heavy load. A 7x16 enclosed with 3 motorcycles and some gear/luggage. I'm not looking back.
