I saw this video on YouTube that explains driving habits and maintenance for Ford's 10 Speed. The video addresses some of the full size trucks but it seems very applicable to my 2019 Ranger which by the way is heading back to the transmission shop next week.



If you hate clicking on link (yes I do)

Here is the title on YouTube. "Ford Just Killed the 10-Speed - The 2026 Fix Changes Everything".

They didn't really kill it, but it offers suggestions.

Keep in mind they don't specifically mention the Ranger but it rings true to me and many of these recommendation are found across the various threads on this 5g site.

Transmission Fluid Changes every 40k miles
Check transmission fluid when its at correct temperature.
Add fluid as needed.
Perform adaptive learning after fluid changes and adding fluid.
Use Tow/Haul mode on hills even when not towing to prevent it from struggling uphill

Can't remember everything, curious on your thoughts.

Interesting - I'm a little confused at the tow/haul mode on hills even when not towing. I've never felt like my truck was struggling in the least on hills - EVER.

Only thing I do on hills is if in cruise control I put it in sport mode.

I use cruise control as Chris @Chris M said exclusively, and it does take a lot of stress out of the drive.

Uhh, this is an AI video that is just a bunch of stuff scraped from the web.

No, you don't need to clear the adaptives after changing fluid unless you're changing severely degraded fluid.

If you want to use tow/haul all the time, sure... I never did, but some people like the way it shifts.

The 10R80 video I'd like to see is one that tells you how to "help" it fail without voiding your warranty... just the absolute worst things you can do that dont fall under "abuse" ...

When you drive in (S) it turns off Tow anyway, keeping your RPMs a little higher
I almost never ever drive in (D) towing or not...
I do wait till it warms up a little like the end of the driveway before shifting to (S)

Just had to have my transmission replaced at 57,000 miles. Left me stranded on side of road in Death Valley.

$1,000 tow to nearest Ford dealership, which didn’t have a Ford certified transmission tech on-site, so another $380 to have it towed to another dealership.

Error codes lit up like a Christmas tree. Service department said the computer screen couldn’t display all of the codes when she pulled up the status report. Said there was a service bulletin.

Thankfully under warranty, but barely. Still had to front all of the money for tows and rentals cars, but Ford is supposed to reimburse up to $1,000 for my expenses.

Lug the truck.

It is not good for the engine or the transmission, but Ford has programmed it to lug in search of EPA mileage goals. I've been monitoring TC slip and Trans fluid temps. The transmission heats up relatively quickly when starting to move. Torque Converter slip really rasies the trans temps pretty quickly. And hot fluid is an enemy to the transmission.

I've learned how to minimize the trans fluid temps, and will be lowering them soon.

I can't stand the lug, and I would NEVER do anything to to abuse my perfect little 2.3 ! I absolutely LOVE that engine and that makes me hate the transmission even more when it clunks around and acts like damnit... luckily for me , it shifts pretty damn good in sport and tow if I'm somewhat aggressive (which i almost always am) but slowing down and stopping and parking lots is downright embarrassing, so I try not to do those things and just keep my bad foot pressin down on the go pedal...

The transmission fluid will stay cooler longer if you can minimize Torque Converter Slip. It will ultimately reach ~200F. I of the persuasion that this is too high (I don't care what Ford says!) I watch the fluid temps realtime and my transmission is at its best at 150F - 160F. 170F is not bad, but by 180F it starts to degrade a bit.

I also think the fluid takes a severe beating when it is above 200F. And it won't last as long. At 15K miles, my fluid was shot... black as coal and the transmission was misbehaving badly. Changed the fluid, and filter, and then had it relearn. Been 99% better since, but I want it to last, so I am going to (attempt to) add an external air cooler during my next round of maintenance later this winter.

While sitting at stop lights, slips and temps climb, once moving slips pretty much stop, but starting off slowly prolongs the slip a bit. I've noticed temps go up very fast when the TS is slipping (poor design I think), and drop much more slowly.

I hate it too, and Ford really was much too aggressive in that department. The thing hunts gears too much as well.

Transmission is heated by coolant. You can by pass it, but it is also cooled by coolant. Double edged sword. Not sure if it is an electric thermostat or not. I know the mustang folks modify that part of it.
