10R80 the beginning of the downhill slide?

Terrible advice.

The CDF problem doesn't do what he's described. What he is describing is sluggish valves, and those can absolutely be helped by fresh fluid and LG.

No one should ignore fluid changes in these transmissions, it might not (or rather won't) prevent the CDF problem, but it can help your valve body to live a longer life.

Constant premature transmission fluid replacement is just a fancy way to piss away money. If that's what you want to spend your money on, enjoy doing you.

If you've really got issues it's better to get them fixed per the TSB (one of the steps addresses the valve body specifically) rather than trying to paper over them with magic transmission juice. If you don't have issues, don't waste money on unnecessary transmission fluid, even if the salesman assures you it will fix any transmission problems, grow your hair back, and save money on blue pills.

Except that there is a growing body of evidence that valve bodies are being hurt by contamination. None of the TSB's address that. The only way to prevent valve body wear is to get the contaminants OUT of the transmission.

Those issues are only going to get worse as time goes on, IE the trans is out of warranty. Then you are left footing the bill for it. Plenty of transmissions make it the whole way out of warranty and act up, so the only 'solution' to that problem is to keep the fluid clean and prevent the wear in the first place.

There is more than 1 defect. And fluid changes and LubeGard Platinum corrects many of them. If the CDF drum slips, it is game over, but that is just one of many issues with the transmission.

If the problem is in the valve body and associated solenoids, a fluid change and LubeGard Platinum will eliminate the issues. And valve body issues will cascade into other more serious issues, such as burned clutches, and damaged gears from lack of fluid or very hard shifts.

I had ALL of the symptoms beginning at 5K on the odometer and becoming crazy by 18K miles, hard shifts, slow shifts, refusing to shift, refusing to release coming to a stop. I never had it jump gears or get stuck in gears, but it was coming... I simply stopped driving it for about a year when it lurched unexpectedly into traffic... we considered it unsafe to drive..... until I was ready to simply unload the truck, or fix it.

Several on this forum mentioned LubeGard Platinum and fluid change. I waited until Fitz had his dipstick ready and own the #4 dipstick. I installed the dipstick, sucked out the fluid though the tube (black as coal oil) and replaced with new fluid and LubeGard Platinum. 99% of issues were gone on the first drive after the fluid change. Still had a slightly rough and noisy shift from 5-6. Waited 1,000 miles and repeated the process again. Drove it 5K miles this time without issue. Changed the fluid again when I installed the PPE Deep pan and changed the filter while I was in there. 8,800 miles since the first change with 92% clean fluid and LubeGard and my transmission is perfect.

I figure ~$500 and a little labor is far cheaper that $6K. Many would probably be happy at the 1st fluid change with LubeGard Platinum.

And yes when it first began I went the the dealer route and was told it drove fine, nothing wrong, they all do that. I never went back. But to be fair, this was before the transmission onslaught began. I was at the very tip of the "reporting transmissions issue cycle".

Man, I hate coming back to the 5G and seeing these 10R80 threads.

Contaminants don't just happen. Most likely reason for them in a 10R80? It's already eating itself.

Automatic transmissions, by design, shed particles constantly.

The same fluid that flows through the valve body is the same fluid that lubricates the the clutch plates and steels, the two biggest particle generating pieces in an auto trans. Every time a shift happens, particles are shed from those moving assemblies. Both organic material (clutch fiber) and inorganic (aluminum/steel). Hence, contaminants. (And while the magnets might grab on to some of the steel particles, you still have abrasive aluminum and organic bits to deal with.)

Most are caught by the filter, some are smaller and make it through. The only way to get rid of the smaller, abrasive particles, is to get rid of the fluid.

--Edit--

Even if Ford replaces your valve body, the new ones are not upgraded with improved materials, so you'll still be in the same boat of premature valve body wear.

The TSB's are not designed for long term owners. They are designed to get people out of warranty at the least cost to FoMoCo.

When the outside temperature is in the 30's to low 40's, First drive of the day after sitting all night I
get a delayed hard shift when it's going into second gear. Am I on the long tortuous road to a transmission failure? Only when it's cold outside. Haven't noticed when it warms up a bit. Maybe needs fluid? I haven't noticed any leaking

Same for me... exactly the same... ?

 

[TJC]

The worse cold shift I had was first start in the mid 50F's (Truck is a garage queen). Doesn't get that cold here in central NC... I started and drove out the driveway... didn't get 500'. I could hear the solenoids transitioning and taking 3-5 seconds per shift to do so.

It hasn't happened since I changed the fluid and added LubeGard Platinum.

YMMV

Did exactly that lmfao. Two transmission replacements later on a 21’ with 67k miles on it and I was fed up. Not sure how the new gen ranger is but my 25’ off road Tacoma is a night and day difference. I was wanting to go with a ranger raptor but couldn’t bring myself to it after the issues I had already.

Hopefully they resolved the issues. They were having lots of replacements under 1k miles on the 8speeds transmissions last year.

how many miles on it now?
I’ve got 70k with shift issues.

 

[My12SecRanger]

Mike make sure to reset the adaptive learning values after you transmission service it can help with irregular shifting issues

 

[stringbreaker]

After all was said and done the truck sits at the dealer right now waiting for a transmission rebuild. All this talk about it has to learn and the fluid needs to be changed and put in this additive is a bunch of Hooey. Ford designed a piece of shit transmission using cheap parts. I'm not happy with my dealer service department right now and from now on will use a dealer further away from my regular one. I bought the truck new from them and they have serviced the truck regularly and done all required services

 

[TJC]

Mine starting acting up very early. By 15K miles it was serious enough that I stopped driving the truck. Did the fluid changes over the following 3K miles. By 18K it was shifting normally again. At 27K miles now. Problem free.

 

[Trustable]

I don’t understand why people are recommending snake oil for the transmission. It’s a badly engineered product. No amount of mystery oil will fix it. That stuff would not have stopped my transmission from having 2 stuck valves due to large metal chunks. My transmission after the rebuild without the CDF drum is already having the same issues just over 2k miles later. Ford and their associated processes and products are the bottom of the barrel at this point. If people think that the transmission is fine you just need to change the fluid and add snake oil, fine, but please don’t be telling others that’s all they need. There is enough failures on here to prove the issue is more than just not having lube guard.
