2019 ranger loss of power / shaky / transmission issues

[James Plastina]

Hi everyone. I have had problems with my truck for years now that the dealer seems to think is acceptable. About 5 months after purchasing my 2019 ranger it started to randomly lose power when shifting, especially in the morning after sitting all night, or when it was cold. The issue was definitely TSB: 19-2052. I took it to the dealer and they re-flashed it. I was told the loss of power was transmission related. Since then, on random occasions, it would still lose power. But not often enough to prove it to the dealer. So frustrating.

Now my ranger has about 24'000 miles on it and its doing the same thing but more often. loss of power, shaky, erratic shifting. I've taken it to the dealer and they say the truck is running normal and i have no codes. Ford doesn't seem to care. I was about to just give up and deal it but then i read about a class action lawsuit pertaining to this problem but excluding ford rangers. I posted the link below. I guess my question is, is anyone dealing or dealt with this? Should i fight ford and demand they fix it? I really am kind of pissed that my truck is fairly new and rides like a 20 year old piece of shi* with tranny problems. Any advise would be greatly appreciated.

As far as a feeling of lost power. If I happen to sort of think about lifting at all when it goes to shift, especially up to 4th when overnight cold, it feels like it gets a bit silly with the amount of power lost. Since the last relearn it has gotten less weird with that, but I also connected the dots with it happening if I let up even a little tiny bit during an upshift, so I sort of adjusted to it. The amount of "power drop" is not proportionate to the "lift" on the throttle; not in my head anyway. On mine, I am not 100% sure if it is some weird e-throttle stuff going on, just in my head, or something the trans itself is doing.

That was before and after the tune. Less crazy after the tune, but still sort of crazy overall.

On the class actions. My wife had a cobalt she got a long time ago that was actively attempting to kill her because.. too many keys on the key ring. Total paycheck from that (other than getting it fixed) 100 dollars. So.. GM paid something to her - not sure what the lawyers cut of her portion of that mess was... but probably a lot more. Good luck if you join against the 10spd - assuming it expands to cover the Ranger as well.

I had the same thing with my 10R80 and a re-learn solved the issue. Not saying it’s going to solve every issue, but maybe try re-learning again?

same problem with mine. mines been to the dealer for transmission issues 3 times. still has issues with transmission. warranty is worthless. what i learned so far- dealers will perform the flash to relearn, if it comes back and happens to be lucky enough to act up while they have it and cannot deny it, they will replace the valve body and flash again. After that they will do nothing unless the transmission is totally fried and they cannot find a way to deny the warranty or pass blame. they do not want to do warranty work. they loose money and time vs. full paid stuff like oil changes and wiper blades.
i cannot prove with data so take it for what its worth - a number of 5g trucks left the ford assembly lines with transmissions not filled correctly with transmission fluid. half a quart to 2.5 quarts low is the range ive heard.
the first 10r80 valve body was poorly designed. the transmission starves for fluid when cold, and gear hunts, hangs, slips, shakes etc. the lack of fluid mixed with design issue and stupid shift strategy make the transmission run hotter than expected slowly damaging clutches and so on. The new valve body is an improvement over the original. low fluid from factory mixed with flawed valve body and then miles (esp as ford does not recommend a fluid change for a long time, and made sure we could not get to the transmission dip stick to check) so transmission problems show up.
Ford knows this. dealers know this. but ford is betting most of the 2019 to 2022 trucks with the issues have passed or will soon pass the warranty period. most dont have any issues that can be presented at the dealer bad enough to fix until the base warranty of 3year 36k is about done or expired. they know your mileage and driving habits and all the info from the truck with fordpass and internet connections. so fords gamble is safe. but screws the customers. ford has instructed dealers to only do what the 2 tsb allow for if the truck meets the precise requirements laid out and the truck shows problems while in dealer hands they cannot blame on you.
recommendation : take it to a trustworthy transmission place and pay to have them check the transmission fluid. document every single step and have them measure how low it came from the factory - if it did come low. If its low add fluid, documented of course. go to a different ford dealer for the transmission, the shorter the drive the better. see what they say. they may offer the valve body swap, or flash or both. if they do drive it and see how it goes. some folks have said that fixed it for them. it did not for me. save all the documents and proof of complaints. in the future when the clutch damages start to get worse and eventually give up you may have a chance of coverage if your documents satisfy ford dealers / ford for being a reported issue unfixed while still covered despite customer complaints. good luck.

I had drivability problems with my 2019 Ranger XLT FX-4 from the day I bought it. I bought it used with 12K miles as a certified pre-owned vehicle and had the idea that the dealer's shop could/would solve the issue. Not only did the dealer not make any effort to find/fix the problem beyond re-flashing the tranmission, they did their level best to try to prove to me it was normal by having me drive other '19s that did the same thing. I got Ford involved and took it to another dealer, where I got the same treatment. I followed forum advice and drove the truck at city speeds in either Tow mode or in Sport gear and lived with it.

A couple of months ago I saw the thread on here ( Bucking/Surging Epidemic | Page 17 | 2019+ Ford Ranger and Raptor Forum (5th Generation) - Ranger5G.com ) where the problem had been solved by replacing an $18 dollar EGR differential position sensor, part number KA1Z-5L200-A. I put the part on myself and no more bucking, shuddering or shaking on acceleration. My current mileage is 38K, I put up with the problem for 26K miles when it could have been fixed if the dealer had simply tried to troubleshoot the issue.

There are numerous posts and threads on her that I believe are describing the same issue with different terms. I believe a lot of the trouble we have had is that we tend to describe the same issue differently. Some call it a shutter, some call it a shudder, surge shimmy, shaking or bucking. It felt to me like the bucking that one would experience while driving a manual shift vehicle at too low a speed in too high a gear.

I wrote a letter to the dealer owner and service manager and told them that since I had solved the problem myself, the least they could do is reimburse me for the part. Of course, to date I have had no response. I am shocked beyond words over that....

Anyway, if you can do the mechanical work, it's worth spending under $20 to try it.

Best of luck

Thank you for the replies. I am going to try this KA1Z-5L200-A sensor. oh, also wondering what is this DPFE pressure sensor is? Part LB5Z-9J433-B . Did you replace that too? or that for a different year?

Crappy Ford service is 100% why I let go of the Ranger. Violent vibrations made my back hurt on longer drives. Was this way bone stock only 3 weeks into ownership from brand new. Had alignments and road force balancing with no luck. The last straw was when Ford techs said its normal to vibrate. Tried other dealers but nobody within 100 50 mule radius had NVH scan toils to isolate the problem. I refuse to spend another dime trying to correct the problem on a new truck I paid $31k out of pocket on. Sorry but no more Fords...ever

LB5Z-9J433-B is the sensor with the hoses and bracket. The other number appears to be only the EGR differential pressure sensor.

hi bill, the sensor you replaced is it easy to get to? something a non skilled parts replacer type of person can do ? im at the point where im willing to try it to see if my truck acts better.

I just returned from a weekend trip of about 500 miles, driven at highway speeds but not on interstates. My best gas mileage achieved on the road before I changed the EGR differential position sensor was about 23 mpg. My mpg on this trip was 27.6. Finally, I got the truck I thought I was buying three years ago.
