10R80 transmission poll.

[Dr. Zaius]

Ford authorized CDF drum replacement and service advisor said she will add additional repairs based on what they see.

That's big time burnt.

When clean, the ULV fluid is difficult to even see on the dipstick.

Worse than it should be for 45,000 miles?

Eeewww

I don't know.

Mine didn't look that bad and it was rebuilt at 36k miles.

 

[TJC]

Mine was black at 18K miles.

If you never drained/filled/flushed the fluid, then that's actually probably about normal. This fluid gets pretty dark even though it's not "burned". When I did my first drain/fill (I don't recall the mileage... maybe around 30k?) the fluid was very dark.

Yum, french fries!

KRINKLE CUT FOR SURE.🫡

It is amazing what we accept as normal... I guess it is all about the definition of "normal".

The high fluid temps that Ford has set as the "normal" operating range rapidly oxidizes the fluid, stripping the fluid of all those fancy protective additives that protect an already delicate transmission.

I wish Ford would publish a bell curve timeline of transmission life of the 10R80. A few variations would also be nice, perhaps based upon how the truck is driven. I suspect those who keep the power band higher, preventing lugging, have the longest transmission life.

On the surface, this is completely opposite of what one would expect. But Ford has pushed the shift patterns of the transmission to the highest possible gear as quickly as possible in a vain attempt to increase / meet the current CAFE requirements, even at the risk of premature mechanical failure.

You can't cheat on physics. This design decision combination creates a very demanding mechanical environment the wears out the fluid far sooner than I think the Ford management team calculated. They simply reached too far and cut too many corners in their attempt to meet unrealistic federal government mandates while still maintaining profitability.

It has cost them 10 of billions of $, and the pain resulting from these decisions hasn't yet crested, the warranty cash flow tsunami is still rising and eating at Ford's financial foundations. They will survive short term, but long term viability is threatened unless they begin to listen to their engineers over politicians and bean counters.

2019, 18k miles, no problems.

When I had mine rebuilt (ford refused to do CDF drum) they didn’t say anything about oil but had tons of metal and deep gouges causing valves to stick. I feel like if it was that dark they would have told me but maybe not. Just my 2 cents

 

[OldHippy]

Yeah, I’m going there
This is to try to get an actual feel for the percentage of forum members who have actually had to have transmission repairs / replacements ( warranty or not) as compared to those who have never had their Ranger in for transmission related issues.
We often read that it’s only a small percentage of owners who have issues resulting in repairs or replacements. Hopefully this sheds some light on that claim. Thanks for participating

Im at 50,000, starting to feel weird shifts. Occasionally. Bought Mike's long dipstick and new pan w/ drain plug and filter.
How much fluid will it take to refill it? And didn't I read hete somewhere about putting a. Additive in? Ill measure what comes out. But just curious about how much to have on hand. Thnx.

If you let it sit overnight, ~5.5-6 quarts through Fitz's dipstick. Let it sit 2 nights and you'll get ~7.5 quarts. That will get you around 60% clean fluid. Do it 2 more times in 1,000 miles and you get to 95+% clean fluid. I use this inexpensive pump.

If you're pulling the pan and changing the filter, ~8.5 quarts

Then add LubeGard Platinum.

Thnx. I did get the cheap little pump. And yes, I am dropping the pan to install the new pan with drain plug. Thanks for the response. So. ~8.5 Plus the LubeGard Plat.
Got it.

I need to clarify... I have a PPE Deep pan installed. It holds 1.75 qts more than the plastic Ford pan. Whatever you pull out needs to be put back in + any additional capacity that your new pan has.

I used two 1 gallon jugs to capture the old fluid, but I marked the jugs with a sharpie at 1 quart increments. ( added a quart of water marked, repeat 4 times per jug. I also added a brass fitting to the hose output end to insure the hose stayed in the jug. It is going to want to curl and climb out if your not careful.

The insure the fluid level is correct when your done, use my cold measurement procedure. It is simple and accurate. The Fitzstick makes this check very simple, accurate, and quick.

Start the truck on level ground after it has sat unused over night. immediately shift through the transmission from park to drive and back to park at 5 second intervals, then immediately check your dipstick. The fluid should just touch the tip of the dipstick... 1/8". Don't wait 5 minutes to check it, the fluid rapidly expands and your results will be artificially high.

I used a ScanGauge III to calibrate the levels on the dipstick image below. They represent the same fluid levels at different fluid temperatures.

To be safe, I wanted the fluid to be dead center on the diamond between 4 and 5 at 215F. This is Fords upper temp level right in the center of the acceptable range window of 4-5.

Conservative, but safe.

It is very easy to overfill the 10R80 and not know it until fluid temps move higher, and you will not hit those temps by simply driving the truck in normal situations. It took 38+ minutes idling for my truck to reach 180F. And I had to power brake the truck to reach 215F.

Ok. Thnx for the detailed explanation. .ine is in body ship right now. Clown ran into side a few weeks ago. Luckily I had my dash cam. Because he tried to say I hit him. Soon as I send video to cop, he made other driver at fault. His ins. same thing. Didn't want to cover till I sent them the video. Hope it will be done thos week.
