Maybe it’s already been talked about in here but. 10R80 and 10L80 transmission 10 speed automatic specifically: Is the best reason to run ULV fluid the EPA? And shorten the life of your transmission, and decrease function? Is the best reason to use thicker/higher viscosity transmission fluid to...

NO Ford has definitely NOT fixed their 10 speed transmissions. Unless you call ignoring it and fighting in court a fix. My 10r80 already started having problems at 2000 miles and finally it got so bad that Ford eventually put a new 10r80 transmission in my 2022 into STOCK Mach 1 handling package...

The ford 10R80 is a PROBLEM also. GM and Ford made the turdo together.

Thank you. SIU/Southern Illinois University also has a great series on the 10X80.

Va. Is my state if you where asking me.

My car sat in the hail, snow,etc since Nov. 19 at the dealer. So after not answering my calls or returning any of my six or seven messages I left I finally drove out and in person tried address management there I did find one manager spoke with him. He never apologize for not returning my phone...

Va.

I have no idea. The dealer mostly refuses to communicate with me. After leaving multiple messages on the service writer’s phone and the Service Manager‘s phone and I think the manager of those two they refused to call me back. I finally had to drive down there and attempt to speak to them...

I test drove with 550 miles bought with 608 that evening. Bought from a FORD dealer. Still under bumper-to-bumper and drivetrain warranties.

I just sent off my info. To a local news agency also. Thank you folks for your wisdom so far!

This guy is good also: I have others.

I would like to get Ford to give me the money to have a high quality shop fully rebuild my transmission with properly designed and manufactured parts. OR Remove the known multiple faults transmission and install a properly fully built transmission. SIU has a 4 out of 8 series documenting most...

I already contacted them but have gotten conflicting information. This is why I am trying to see what results others have gotten.

This time it has been at a dealer for 67 days and counting. In Va. 2022 STOCK FORD MACH 1 Mustang. Started having 10R80 transmission problems at 2000 miles now the car is at 9000 miles. How long can the dealer keep my car without fixing it, or fixing it? How long before the manufacturer paid...

Which lubeguard product? I have a 2022 stock MACH 1 Mustang with 9k miles. It has been at a dealer this time for over 2 months and no loaner. I do not know what the #@*k Ford and the dealer are doing. Are they incompetent? Crooks? Or both? When I first took my car to dealerships, they told me it...

I feel like this is great information for anybody with a 10R80 Ford or GM 10L80 transmission: My impression is that a large part of the problem is not just the valve body, but the transmission eating itself and then filling the valve body with aluminum and steel shavings. Then...

I talked to Steeda today and they have their transmissions rebuild every few months

(In the 10R80, planetary gear sets and the one-way clutch are vital for maintaining smooth gear shifts and appropriate gear ratios. Deficiencies in these components can lead to improper shifting or transmission failures. A faulty one-way clutch might cause skipping of gears or failure to hold...

Would this fit, be a great fix/upgrade: The 10R140 is the largest 10R family member and was originally rated to 1,050 ft.-lbs. of peak torque in the 2020+ Super Duty. This has presumably been revised for 2023, as Ford debuted the 6.7L High Output PowerStroke, which makes 1,200 ft.-lbs. of peak...
