Better performance after transmission oil change ?

[flyerjaz]

Has anyone seen an improvement of the operation of the truck after changing the oil in the transmission?
Thanks.

Why would you?
(See any difference)

The "operation" would stay the same with no oil at all, up until the point it grenades.... probably thousands of miles later.

Your eCVT is much “gentler” on transmission fluid than an EB - which depending on mileage can see improvement (or degradation) depending on mileage.

But changing the fluid in your eCVT will be akin to changing your engine coolant. Probably won’t notice any performance change…

How often do you change the eCVT fluids.

How often do you change the eCVT fluids.

Depends on how you drive. The manual says 150k miles, but fine print says this for for people who aren’t in stop and go traffic and mostly drive on the freeway. For most people 5-6 years or 60k miles, whichever comes first, is a much better schedule to go by.

Car Care Nut speaking about Toyota's similar schedule for similar eCVT - recommended for true longevity that Toyota's are known for - about 7.5 yr/75k miles.

The revised e-manual that was done for 22-24 after 25 came out says this:

Other Maintenance Items 1​
Every 20,000 mi (32,000 km)	Replace the cabin air filter.
Every 30,000 mi (48,000 km)	Replace the engine air filter. For severe service, Change the automatic transmission fluid.
Every 60,000 mi (96,000 km)	For severe service, Replace the spark plugs.
Every 100,000 mi (160,000 km)	Replace the spark plugs.
	Inspect the accessory drive belt or belts. 2
Every 150,000 mi (240,000 km)	Change the automatic transmission fluid.
	Replace the accessory drive belt or belts. 3
At 200,000 mi (320,000 km)	Change the engine coolant. 4

1 Perform these maintenance items within 3,000 mi (4,800 km) of the last engine oil and filter change. Do not exceed the designated distance for the interval.
2 After initial inspection, inspect every other oil change until replaced.
3 If not replaced within the last 100,000 mi (160,000 km).
4 Initial replacement at 10 years or 200,000 mi (320,000 km), then every five years or 100,000 mi (160,000 km).

What Are Considered Severe Driving Conditions
A vehicle that is driven for short trips of less than 5–10 mi (8–16 km), driving in temperatures well below or above average, driving in any dusty conditions, idling more than recommended such as in traffic, and driving with a heavy load or while towing a load are considered severe driving conditions. If the vehicle is driven in any of these conditions, follow the severe service maintenance items listed in the scheduled maintenance chart.

If I had the eCVT - I’d do every 4 years. Going to every 2 years on my EB. Overkill on both for sure - but I DIY & enjoy getting under the truck

This does not sound hybrid oriented.
The hybrid does not have an automatic transmission. But the EB does.

The hybrid does does not have accessory drive belts. But the EB does.

Ya - the whole service schedule and even that fuel section is pretty bad about separating things out for EB vs hybrid.
Some things exist, some don't.

I wanted to get the severe driving details listed - not a matter of sometimes every blue moon - but mainly.

Next section in manual has this for General Maintenance, which is VIN specific entry:
Scheduled Maintenance Service Intervals
For your scheduled maintenance service intervals, visit https://www.ford.com/support/maintenance-schedule.


Bottom of the section for your next check always says this:
The information contained in this chart is summarized based on vehicle mileage — see your Owner’s Manual for complete scheduled maintenance information.


Sadly this online resource skips the 50, 70, 110, 130, 170, 190K list entirely - so how good it it's accuracy?

Perhaps a tad more specific to hybrid since VIN based, 30K does NOT include ATF, and:
Here's what happens at your 60,000mi checkup:

• Replace cabin air filter, if equipped.
• For severe service, replace the spark plugs. (4cyl)
• Replace engine air filter(s).

Or maybe not!
Here's what happens at your 100,000mi checkup:

• Replace cabin air filter, if equipped.
• Inspect accessory drive belt(s).

Here's what happens at your 150,000mi checkup:

• Replace accessory drive belt(s) if not replaced within the last 100000 miles (160000 km).
• Replace engine air filter(s).
• Change automatic transmission fluid.

I think we have a hidden accessory drive belt somewhere - it's on every mileage check after 100K! Better find it!

While I trust the OLM due to it changing time/distance based on the driving seen - proven out by many reports - some of those other systems I'm not so sure, once it goes too far damage can be done.

Coolant - supposed to check the strength each 6 months. Mine's getting stronger. (reminds me I forgot to note level at last fillup, I think)

I guess they hope this coolant is good for that far out. Though above chart says 10 yrs/200k:
Here's what happens at your 200,000mi checkup:

• Replace cabin air filter, if equipped.
• Inspect accessory drive belt(s).
• Change yellow engine coolant.
• Replace spark plugs.(4cyl)

Here is a pic of the transmission fluid filter in the hybrid. It is bolted to the fluid pump inside the eCVT. Can’t replace without eCVT removal & disassembly. Meant to outlast the eCVT. With old dirty fluid, however, it may wear out a few weeks before the eCVT croaks

Edit - picture from this YouTube tear down video:

Hybrid here, I just changed mine 2 weeks ago, very easy, I did not notice any change in performance
