Hybrid Transmission Drain and Fill @ 61K Miles

[BoboysTruck]

At 61K miles I decided to do a drain and fill. I watched this video.




Guy in the video said he drained about 7 quarts out so I went and got 7 quarts of QULV at the dealer but only used 3 quarts and 24 oz before fluid started dripping out of the fill hole. So, does the eCVT have nooks and crannies like the traditional trannies where fluid hides?
Anyway, here are some pics.

Old and new fluid.

Drain and fill plugs. No particles on the drain plug.

Also it appears the fluid is cooled in the radiator.

What does ford recommend for the interval?

What does ford recommend for the interval?

From the manual:

Every 150,000 miles

Change transmission fluid.

I will NOT be following this advice.

Thank you for sharing this. The bigger takeaway for me is you have 61k miles on the truck. I know you have another thread where you posted at 50k.

I think we really need to hear more from folks with lots of miles - it gives us hope that not all these Hybrids are doomed to be problematic. If I could count on my truck driving the same 5 years or 60k miles from now as it does today, I'd be sleeping a lot better.

I follow the advice from the manufacturer and their engineers who know their product so I will follow the manual and not do any unnecessary or unneeded maintenance prematurely.

I remember when my wife purchased her 2009 Honda CR-V and during a Service Meeting for new owners (got 2 free oil changes) the head of the service department recommended changing the initial oil at 1000 miles. I pointed out that the manual specifically stated "NOT TO DO AN OIL CHANGE before the maintenance minder said so" as it is special oil put in the vehicle to help in maintaining the long life of the engine. The service manager didn't back off and I wonder how many who followed his incorrect advice are now wondering why they have engine problems.

My 2014 Mazda CX-5 manual has no information on changing the transmission fluid. No interval recomendation, no service schedule, nothing. Personally I wouldn't follow the manual and never change that fluid for the entire life of my car, but that's just me. I'm not here to tell anyone how to take care of their vehicles just offering my own perspective.

They recommend 30k if you have a roof rack.

I barely put 12000 miles a year, So I figure I will be trading my Hybrid Maverick for the new plug in Maverick before I need to change the trans fluid.

I see you’ve never owned a car with “lifetime” transmission fluid.

Kind of normal interval for a hybrid tranny. Changed my last hybrids fluid at 150k, they said it was just starting to look a little dirty. Got the impression from the techs they felt go by 150k or 5-6 years, whichever comes first.

so you took 7 quarts out.... and only put 3.75 quarts back in? how does that math work?

Ummm, I never said anywhere I took 7 quarts out. No need to do the math. Just look at one of the pictures, it does show how much I took out.

As for the interval, I plan on driving this truck until the wheels fall off just like the vehicle it replaced. It had 465k miles after 12 years on original engine and transmission. Matter of fact, it was still running very well except it was overheating due to head gasket problem. Anything I can do to keep it healthy, I will. Like some here say, oil is cheap. Engine and/or transmission not so much.
