Reason number 19,000 to never ever buy an automatic transmission (19,000 also being the number of moving parts)

Triton powered ford ...

We had ZERO problems with the Expedition for about a 100k and gave it to our son.

...He called and ask if I ever changed the plugs?

I said bring it over, no big deal.

He said BIG DEAL!! And explained. WOW!!!

I called a friend that had two of them and had all the special tools plus the helicoil kit if needed.

An all-day project just to change the plugs.

I have heard it can be done in a couple of hours but I was SUPER CAREFUL. (CHICKEN)

Gee, our old LaSalle ran great ...

up until the 1960’s a LaSalle trans was a good thing to handle additional horsepower.

All motorcycles utilize a wet clutch arrangement. Multiple plates bathed in oil. I tell you, my Yamaha 1300 is one torquey SOB.

the internal water pump issue...

I never owned one and kind of forgotten about it.

By the time you notice the water is mixed with the oil, it is too late.

Bathed in oil ? What plates is he talking about ?

Most automatic transmissions have clutches that run in an oil bath.

A simple explanation of a complex device. Seven minutes.

For some real fun have a look at a Prius trans!!!
It makes my brain hurt.

Yes, a dry clutch should be dry! And stay that way.

Most automatics and dual-clutch manuals run in an oil bath.

Pls see the link in #46.

Numbers 1 and two for sure.

Take a gander at the link in #34.

The old guy Munro has been there and done that.

How about the Mopar gen 3 hem that eats cams because oiling is incomplete at idle?

A friend finished paying for med school and was making some money, had the hots for a new BMW. Long ago 1980s???

He wanted a stick, they only had autos in stock...

He loved it but it kept making tappet noise?

He brought it over and I called a BMW guy...

I said tappet noise and he said AUTOMATIC!!!

To keep them from creeping too fast they had to slow the engine idle. Too slow and the oil did not make it to the camshaft!! But you can get a Teflon coated cam!

Got a hunch?

Because I NEVER worked on the insides of an automatic I tended to agree with you.

Since my wife bought a Prius V for a retirement car, I have come to like it!

The Prius Trans is kind of sort of different from all others.
THE MOTOR SPINS BACKWARDS FOR SOME SPEEDS! (I think??).

This instructor is among the best, superb.
If I can follow him anyone can.

NO, I do not intend to work on the Prius, but I need to know how it works.

I have an older Ford truck with the 5.4 Triton 2V motor that is prone to blowing spark plugs if they are not installed tighter than the torque spec but the motor is solid at nearly 220k miles. The 3V Tritons are a nightmare for a couple problems including the two piece spark plug threads. The Coyote V8 in the current trucks is a good motor but I wouldn’t trust the Ecotech turbos and the ten speed transmissions are problematic. I am thinking of getting another truck in the next year but if I do it will be a Toyota.

My mother has a Focus that has been a mess. Three warranty visits for the crappy transmission referenced in this article. Thankfully they bought an extended warranty when they got the car and that paid for itself just to replace the crappy electric steering rack. I have told her to get rid of the thing but she won’t do it.

Learn something every day. Never heard of a duel clutch manual tranny other then the Southbend Duel Disk setup i have on my Ram 4500 6 speed.

Off topic. I sold a 2004 Mustang GT with 140,000 miles and 9 years old which still had the original clutch. May have helped that I have driven a stick for 55 years.

Your truck has a single clutch with dual disks and a floater plate to provide more surface area, for a longer life with heavy loads.

The duel clutch trannys have two complete clutch assemblies. Some pretty clever thinking, allowing you to be in two different ratios at the same time with (obviously) only one engaged.
As you start it is in first, to upshift one clutch opens and the other engages 2ed at the same time.

Some slick stuff but the fluid is usually $$$ and has to be changed often.

Off topic.
I have driven a stick for 55 years.

Not at all off topic!

Over the years you have developed many responses to many, many variables. Wet, dry, fast, slow, maximum acceleration, and lots more. Plus muscle memory to make the clutch do as you wish.
All that and a parameter for long service life.

I’m guessing that if it was a manual set up with your foot feeling the ‘good vibrations’, you could put many miles on it without issue.

Programing your knowledge base into a controller with a mechanical hydraulic operation?
Ford was in a hurry.

Marry in haste, repent at leisure.

PS:
If you have the time, take a look at the link in #34.

Starting at the 41-minute mark and it runs for a few minutes.

Some insight into why Ford did not do it correctly the first time.

I’ll stick with a good old Manual Tranny.
That “Auto-Manual” looks too complicated which means easy to break.

The small potential fuel savings will never be worth the issues that sooner or later will crop up.

It's those God-forsaken CAFE standards driving this garbage. Implemented during the Carter Administration, and given teeth by Obama, they were headed to the trashheap when Scotty Pruitt was running the EPA until Trump forced his resignation.

I will never in a million years understand some of the people Trump has fired, and others he has retained.
