My research into the 10R80 shift strategy

[Squatchranger]

Please stop. They don't adapt to you. This is a very common misconception, transmission adaptives are not for 'learning the driver' they are for the TCM to learn the internal operations of the transmission and adjust parameters to meet defined performance targets.

Just regurgitating what ford says tbh, yes I know that it does adjust based on the wear and other factors of the internals as well.

The programming does blip the throttle on downshifts to smooth out the gear change.

While the Ranger is a budget truck, the 10R80 transmission is the same unit that is used in the Raptor, hardly a budget truck. The only difference is our torque converter and programming to match the 2.3L's power output.

Almost.
According to this, we have 1 less friction and steel plate in the C, D and F clutch

There are differences in the 10r80's in the various models yes, but ultimately his and I's points are correct it does rev match as you downshift. Any idiot could see that by simply driving up to like 30 mph and then slowing down (not calling you an idiot see my prior comments to see who I am)

No fluid changes on the trans?

No fluid change as of yet. I plan on doing that this weekend.

 

[Squatchranger]

No.

So what exactly do you call this? It’s more subtle in auto ofc but it is definitely rev matching… also I had a longer version with all the gears but it was too big a file. All I’m doing is hitting the brakes and downshifting in sport with the button

 

[Squatchranger]

My 10R80 has never went into 9th or 10th at 20mph, that is insane, and would be lugging the engine below idle or fighting the converter to even go down the road.

Mine has, however:
- Squealed tires when engaging reverse (harsh, delayed engagement)
- Locked the back tires up when going down a hill at 10-15mph and selecting 4-3-2-1 from the shifter in “D”
- Gotten stuck between gears with zero propulsion (but engine still revving), then slams back into gear when it figures itself out.

All of these were resolved with a tranny reflash and relearn at around 7-8k miles. Truck now has 15k miles and no issues so far besides the lock of rear tires upon downshifting on steep hills, feels like the TCC clutch is delayed on releasing.

I may go back in for a relearn soon, as it took another 7.5k miles before any odd shifting stuff came up.

You need transmission service beyond just the reflash

Without known the situations or conditions this is happening I cannot comment on what you say is occurring. All I know is mine has never down shifted on its own hard enough to chirp the tires when decelerating. If you are manually forcing a down shift, either in "S" or locking out gears in "D". Then yes it will happen. The transmission does not speed match on it own and will only delay the shift to avoid overreving the engine.

see the video I posted it absolutely rev matches and doesn’t chirp? You’ve got something wrong in yours, as does the downshifting in d guy

Anyone here reached 95K miles yet?

No but I got a buddy with a '19 Lariat that has, and his tranny is doing the Msfitoy thing...he's had two valve body swaps (probably rebuilds) and still doing the weird shifts and lugging/bumping....

Funny this post happened. I was talking with the guy that rebuilt my old Rangers tranny 4r44e. I asked him about the 10R80’s and if he’s worked on any of them. He grinned and said he expects to see more of them. As delivered the clutch packs aren’t the greatest quality they shed as they wear and the solenoids are magnetic type. They accumulate magnet debris and will stick. (Possibly the slam some experience) He also said the torque converters are problematic too. Not enough pressure and things start slamming too. His suggestion to me was do fluid changes often and change the filter. If you do decide to rebuild he suggested getting a better quality valve body, raybestos clutch plates and a new torque converter. He said he hasn’t seen one implode yet but never say never!

 

[Msfitoy]

Yes. Original tranny. So far the only hiccups I’ve had is some rough downshifting here and there. I still need to do my 100k mile service, transfer case and rear diff services this coming weekend. I’m hoping with those services it’ll last me another few years. I’d say 100k is highway miles as I’ve used it mostly commuting to work. I just added the Eibach Protruck 2R coil over lift kit, Borla S exhaust and ordered my front/rear bumpers from SVC off-road last week.

I'm assuming that this isn't your first diff oil change at 111k?

This actually will be my first diff oil change.

SO...reading all this I have to ask a question. We are, here in this forum, a microcosm of the total number of Rangers floating out there with 10R80's. This is, in form, function and build, the same as the F150 transmission.

That being said...how many of this issues are being noted vs the total number of transmissions that are NOT manifesting any issues?

Second...I've already been reading about the expansion of Ford's 2.7 / 3.0 engine investigation. This does not bode well for the blue oval.

Where will be at with these transmissions IF they are the ticking bomb that we are all thinking they are?

For reference - I've seen Honda proactively extend warranties for many of their vehicles for possible issues - our AC condenser for one in my wife's Civic.

With the total vehicle output of Ford vs Honda I don't see Ford willingly doing this.

I guess what I am asking is...who has the crystal ball? Who see's the future for the little 10 speed that tried but couldn't?

Needs to check the cdf drum itself there will be damaged components in there

 

[RedDakooter05]

I halted the strategy on mine, problems solved.


But damn good work on your part.

Yes he is at present trying to shake a new tranny from Ford

Almost.

Good to know. I would have thought that economies of scale would have prevented that, but nice to know (joke) that Ford is squeezing every dime out of them.

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

Also, as the aftermarket starts rebuilding these things, they'll start adding those steels and frictions back in just like they've been doing with old school 4L60's and 4L80's. Most rebuilders routinely add clutches back into their packs and the 10R80 will be no different. Sonnax or Transstar will come up with replacement drums machined for that and most rebuilders will just build them to 'raptor' spec with the 'missing' clutch plates.
