Transmission Fluid Change

[Frogdog1]

Since, as far as I know, Mustang GT's don't have dip sticks or a transmission fluid change recommendation, what are other's doing to keep good fluid in their 10 speed automatic transmissions? Thanks, FD

Not ordering the 10 speed auto to begin with. Get the 6 speed manual!

Joking aside, just change the fluid every 30-40k miles.
Don't listen to any lifetime fluid nonsense. What does lifetime mean... basically until the warranty period is up. Manufacturers would prefer to keep that dirty fluid in the car to help wear out the vehicle faster and sell you yet another new car.

Maybe refer to the Owner's Manual, page 438 specifically.

I am obviously not buying into any "lifetime fluid nonsense" and I own a 2025 GT, 10 speed automatic which I like. Had I wanted a six speed, I would have ordered one. Everyone has their preference for their own reasons. Also, on Page 438 in the 2025 GT owner's manual there is nothing about an automatic transmission but thanks anyway.

That said, back to the original question: " What are other's doing to keep good fluid in their 10 speed automatic transmissions? Additionally, how are other's changing out their transmission fluid? Thanks, FD

I was going to do this myself on my ‘19 did the research and eventually decided to take it to someone I could trust. I bought the kit from LMR and had it changed out at 35k. Much easier for me and paid 2hrs labor. Look on the M6G forum for information.
