My research into the 10R80 shift strategy

[ccasanova22]

Rev matching on downshifts? This isn't a BMW or Mercedes. Or even a Mustang or Raptor.
You guys are expecting a lot out of what was supposed to be a budget truck and was an outdated platform when it showed up in the US.

I'm not sure if I am explaining the problem well enough, but every automatic transmission (and even the ones on U-Haul trucks) they recommend downshifting when you need to ride the brakes for a long time (i.e. going down a steep hill).

On every automatic transmission, even DCT and CVT, you can select "L" or go 3-2-1 down a steep hill so you don't have to put excessive pressure on the brake pedal.

My '22 Ranger is the only automatic transmission vehicle that squeals the rear tires when going 4-3-2-1 down a steep hill with the brake depressed. That's during a speed of 10-15mph, moderate brake application, and down a steep enough hill where downshifting a manual would easily allow for a 2nd and 1st gear engagement with a blip of the throttle.

So I don't think we are talking about "rev match" per se in the technical sense, i.e. blipping the gas during a downshift on a manual, or double-clutching, but the simple fact that I cannot cleanly downshift from 4-3-2-1 going down a hill without a tire squeal.

That does not seem normal, but every other automatic with a range lockout (read: even hydraulic ones from the 60's) allowed for selecting 3-2-1 without much drama.

You need to have them look at the valve body and shift solenoids, those are textbook symptoms of the issues in tsb 2250 which I and others have had, if left alone youll need a full rebuild or replacement transmission in quite short order.

Well, mine just squealed the rear tires again backing out of my driveway, the LCD screen clearly showed a change of "P" to "R" and 2 seconds later it had a harsh, delayed engagement. This is definitely NOT NORMAL, at 7k when I had the transmission re-learn done it got rid of all this nonsense, now the issues have come back.

Defintiely going to take it in for another re-learn within the week, earliest appointment I could get is next Monday.

And then they went and made the 10R60 which is even cheaper still and I suspect will be in the 2024 Rangers.

I picked up a 2023 bronco with the 2.3 an 10r60 an it shifts night an day better than my my '19 ranger ever did. From what I've read it weighs 60 pounds less than the 10r80 an I assume they use the same case so the weight savings must come from lighter internal components. Bonco's are only rated to tow 3500 pounds so I assume that's why they can get away with the lighter transmission. Seems like I remember reading a member or two in here getting an explorer as a loaner an commenting on how smooth they shift. Were some of the problems/complaints from the 10r80 quietly addressed in the 10r60?

Perhaps Ford will run the 10r80's in the Rangers with the tow package an the 10r60 in the non tow package trucks.

They could be 'smearing' the shifts more in the Explorer as well, which would lead to shortened life, but probably after warranty is out.

Trucks are expected to work a little harder so a super soft shift might not get them through the warranty.

I actually blame about 50% of current truck transmission problems on the public. I've said it in another post that we've turned workhorse trucks into daily drivers for going to the store and toting the kids around. A harsh shifting transmission will piss off Karen and her precious kiddos in the back, so they smooth them up and wear them out sooner.

The other half is the EPA forcing the damned things to upshift so quickly.

Just to clarify, I do not have a “super harsh shifting transmission”. I have an extremely harsh shifting one at times which leaves black marks in the driveway going from P to R, but other times it does the same shift smoothly.

The Tremor IS rated at 19 mpg city and highway. Are used to get basically 18, then I put in the CAI and that knocked me just under 20… Now with the Borla, first of all the power is very zippy, extremely low, RPMs, and then if I happen to be in the crew going under 70… Let’s say 65 to 70, I’m hitting 26 mpg’s. Heck, I had 28.2 for a while. It’s just quite an extreme increase.

Wow. But also, hmmm, that's a 30% increase, and agreed that seems so high to the point of implausibility
Since my '21 ranger always gets terrible mileage since the day I bought it (2wd, XLT), are there any exhausts that are higher-flow but also are no noisier than stock?

I guess I got lucky. I changed my transfer case and both diff fluids one day and all my wonky shifting disappeared. Still haven't changed the transmission fluid yet, but it's on my to-do list.

reset the TCM yourself, don't waste your time or the dealers taking it in.

Now some questions about your P-R tire spin

Are you still in high idle? how firm is your foot on the brake? does it do it once, or would it happen over and over if you tried?

It does it at random, mostly when the truck was first started for the day. My high idle goes away after a few minutes in the summer, but lasts like 5+ minutes in winter. That doesn’t seem to affect the probability of it happening though, I’ve had it at low idle and still hard shift but only once. So very rarely.

I’m firm enough on the brake to get the truck into R, but not burying the brake either. So somewhere in the middle.

It does it once in a blue moon so I’m not overly worried about hitting something but more worried about the long term drive train health as it’s a sudden, jolting shift.

The relearn isn't going to fix anything you have a hardware issue. The seal on your cdf drum went and the valve body got clogged up and the solenoids are sticking. You need to insist they go through the whole tsb including checking the cdf and its sub components. Mine did the same stuff and it had several pieces with huge gashes in them inside the cdf.

But when I downshift with a manual transmission, I blip the throttle so the RPMs match and the rear tires don’t skid.

+1

Manual trans 101

Sigh.... another rapidly disappearing skill.

Very true, our trucks do too, I have a video here that proves it. Ford dealers and even other owners have gaslit us into thinking that rough shifts and not downshifting and chirping the tires is just the truck being quirky and is normal. It isn't, after being fixed mine shifts very cleanly, rev matches all that.

Just to clarify, I was replying to ccasanova22 and talking about rev matching while downshifting a manual. Nothing about the 10R80.

Agreed re: WAAYY too high for reality, but DEF the right direction!!

check around for sure and maybe someone can think of some real high flowing options. MBRP isn’t that loud for sure.
Either way, it was just wild how it woke it up. It felt similar to when I put an off-road H pipe on a 95 5.0 cobra. I think those numbers are generally expected between 10 and 15 hp in the same ballpark of torque.

I would recommend Borla S type, but it is a little louder on the cold start, and you’ll definitely be hearing it. But when you’re driving it, windows app, unless you get on it, it’s really pretty quiet.

I’ve had so many exhausts over the years with different cars… It’s funny because I think , this four-cylinder turbo might be my favorite sound with the Borla. Who woulda guessed!
