How the Ford 6F35 Transmission Works

[@paulvandal4444]

It is very fortunate that your family is so diligent about dental care. Otherwise we would all remain mechanically illiterate. Thank you once again for a very informative video.

[@speedkar99]

You are welcome. Just because I steal the tooth brushes that doesn't mean they're diligent about brushing their teeth

[@me734]

Automatics are a mad science of engineering.

[@speedkar99]

It sure is complex!

[@SplosionMovies]

always a good day when speedkar uploads :)

[@speedkar99]

Glad you like it. It's been a busy last few days 👨‍🍼

[@michaelbezoski3096]

Every video I have witnessed with your dissection blows me away. All the machine work on only one part per say (transmission) and this is but a grain of sand on the beach of millions of vehicles. No mincing words on function. Maybe when your youtube rich you can snag another mattress. 🤭 As others have stated, great job! I like..."always a good day when speedkar uploads". So true.

[@speedkar99]

As an engineer I am also mesmerized by the manufacturing that goes into making these, and to only think on the large scale as to how many of these are out there!

[@kestlovs]

That "straight cut gear" is actually a sprocket. Chain + sprocket makes a bit less noise then a pair of straight cut gears. Thanks for your content. I learn a lot.

[@speedkar99]

Yeah but most transmissions use helical cut gears which are quieter than straight

[@kestlovs]

​@@speedkar99 yes, helical are are quieter then straight. My point was that part with straight teeth is not a gear, it will work in pair with chain and it will not generate the same amount of noise as a pair of straight cut gearwheels. Chains are fairly noisy, though, especially in higher revs. I guess helical gears are quieter then chain.

I loved when i heard swahili words "akuna matata"...that is my national language..welcome to Tanzania brother.

[@speedkar99]

Haha 🤣 good old lion king

[@adey88splace]

Thank you for demonstrating the oil pump fluid flow. I've seen lots of these types of videos and no one has actually shown us the flow of the fluid. Got to love the humour and look forward to your videos.

[@speedkar99]

Glad you like my video style & explanation

[@stevesmith8155]

Interesting how small lower cost components (such as plastic seals or plastic chain guides/tensioners) frequently cause large assemblies (engines/transmissions) to fail. If a vehicle is too reliable it will screw up planned obsolescence and ruin the economy. Always a joy to watch!

[@speedkar99]

Thanks, and yes I agree, it's the small things that can condemn a vehicle

[@fdamien80]

Perfect upload! Got one of these suckers in my 2011 fusion.. 160k miles on that sucker so far and possibly factory fluids.. 1 to second gear is lazy and is noticeably worse in cold weather. 2nd to third is also lazy but not as bad.

[@fdamien80]

Oh yeah, also experiencing slight tourqe shudder(think that’s what’s it’s called)

[@speedkar99]

Change the fluid ASAP

[@jonnyduncan7056]

Top knowledge as always.

[@maxenielsen]

Amazing design. How well do these hold up?

[@speedkar99]

Not that well especially on the escapes

[@setSCEtoAUX]

When I had a 2013 Focus (only car I've ever hated due to the DCT 'box), I always wondered how hard it would be to swap in an automatic from an Escape. Or maybe I just wanted to escape. Anyway, I hope that car has been turned into paperclips and soda cans by now.

[@pfeurta]

Same! I had a 2015 Focus and the TCM would fail once a year. Glad i got rid of it.

[@speedkar99]

Can I have your DCT to teardown ?

[@setSCEtoAUX]

@@speedkar99 If I had it I'd happily send it to you. What I really want to see is someone tear down one of the dual clutch/flywheel packs. There were a dozen revisions of them, but Ford never let me keep any of the *three* they replaced in my three years with the car.

[@oscarlmolina]

Great video. I wonder why they used a chain for the final drive.

[@speedkar99]

I guess it's lighter than using a bunch of counter gears.

[@cintocrunch]

Funny on the Traverse forum it’s widely understood the Ford version is more reliable. I suppose none of them are reliable, the best we could get when two automotive giants put their heads together.

[@speedkar99]

Yeah especially the big 3

[@OliviaZpo]

Each of your videos is a real find! Thank you for your quality content and interesting topics. I always look forward to the new episodes!💥🍭🥶

[@TheCRTman]

I'm always curious where you get all of these transmissions and engines from. Do you just buy them at junk yards to tear them down for the channel or do you buy whole cars for parts?

[@speedkar99]

Mostly buy them as cores from marketplace from people who've swapped or parting out for channel and my knowledge as well. For some I'll buy whole cars, and you'll see multiple videos from that car on here.

[@TheCRTman]

@@speedkar99 I see, keep up the fun work.

[@atx-cvpi_99]

Both the Ford and the GM versions have high failure rates. The Chevrolet Cruze for example had a high failure rate for transmission failures and the engines failing as well. On the Ford side, the Ford Escapes were the highest failure rate for that transmission. The Ford Fusion also have that problem as well. The AWD ones have higher failure rate than the FWD because the PTU failed more often and can cause destruction to the entire transmission like cracked transmission cases. If a transmission is cracked, it’s not rebuildable. It can be used as a core to rebuild another transmission but chances are that there are very little good parts in the transmission.

[@speedkar99]

I've heard the escapes are the worse (probably because it's heavier) and the newer 6F55's in the explorers were bad too

[@totalrecone]

Wot!?!? No Wet Belt final drive?? But Ford says it's a sound technology...true!

[@speedkar99]

Haha that wouldn't make it out of the factory

[@michaelbezos2969]

As an Instrument, Electrical Journeyman. The mining of raw material to finished product, to service life, to scrap or landfill makes you wonder how we're even still here. Once machines make machines I'm kinda thinking "carbon based units" will no longer be needed. 😮

[@giovanni233]

First, also getting this notif while driving a 6F35 is so funny

[@toby2581]

Yeah, I've got one too. Good luck to both of us, based on their track record.

[@giovanni233]

@@toby2581 I did two drain and fills and a half bottle of Lucas stop slip as it would lightly flare on 2-3-4, and it would also feel insane shifting when pressing the gas very lightly going on the 1-2 shift, I also recommend resting the shifting tables using forscan when performing the drain and fill too.

[@speedkar99]

Did it help? I think once it's slipping there's not much you can do to return it

[@giovanni233]

@ it’s not like actual burnt band/clutch slipping slipping, it’s a very very light and subtle flare between gears like imperceptible unless you were watching the tach as it shifted, it’s fords first 6 speed auto and it was also the first to use Mercon LV instead of V too so that also adds to the harshness, it’s really just a meh 6 speed and feels pretty similar to early 62TE’s, I just added the Lucas because this is like the 9th ford (by choice shockingly!) I’ve had and I’m too familiar with how they operate already, but I scheduled a TCM update with the local ford dealership and I will report back if you or anyone cares, but by the first drain and fill and a TCM reset no Lucas the stumbling between 1-2 under light throttle instantly disappeared and the light flaring got better (but would still do it after heavy WOT pulls or sitting in bumper to bumper traffic), then about a week later I did another drain and full and a half bottle of stop slip and another no TCM reset and after about 200~ miles the flare slowly worked its way out and it shifts totally normally, now it just feels like a mushy 6 speed :( hopefully the TCM update will correct that, fingers crossed.

[@giovanni233]

@ oh and if you care too the car I’m driving is an 09’ Mercury Mariner Voga V6 AWD

[@BrightLandsCarFan]

E-torx, torx and hex bolts… are you sure ford wasn’t working with Volkswagen? 😂

[@speedkar99]

No they were working with GM and were pretty open about it

You misspelled "fails" :)

[@willemdodgerford5782]

Uhuh... definately. Thats a lot of gears man. Meth so expensive these days though?

[@speedkar99]

Compared to copper wires yeah

[@pollywollydo]

Wonder how much that cost Ford per unit ?

[@speedkar99]

Probably $1000? There's alot of machine work when making one

[@test40323]

our engine whisperer is talking to a transmission. will he continue his infidelity with ev? :-)

[@speedkar99]

I'll be opening up two hybrid transmissions very soon. One step closer with their electric motors....

[@sergiizheka3571]

Where are the gears? :):)

[@speedkar99]

The planetary gear set that I mentioned

[@waterloo123100]

Your wrong about The 6f35 being less reliable virtually all Gm and ford combinations you’ll find the ford is a more stout transmission. I’ve been in the transmission business for 9 years now.

[@speedkar99]

How many Ford 6F's have you torn down? Did you find the same issues with the GM version?

[@blackindian9554]

I hateeee some of these designs from Ford

[@speedkar99]

Yeah. A bit old school in my opinion

[@hukmai]

Much difference from hondew autos

[@speedkar99]

Yea Hondas are more like a manual

[@hukmai]

@speedkar99 I wonder why the honda 6 speed auto is problematic, after the 2nd revision of the 5 speed making it bulletproof you would think they would have figured it out..or I guess they did since they're on the 10 speed now a far departure from old parallel shafts of yesteryears

[@toby2581]

A non-removable oil filter. Can I sue engineers for malpractice?

[@martin-vv9lf]

not unless you make serviceable filters a legal requirement.

[@speedkar99]

Engineers don't make these decisions. It's the bean counters

[@chuckh.2227]

Sounds like you don't like Fords

[@speedkar99]
