My van has always done that bad shift, but when it had 25k, I was in bumper to bumper traffic when it started doing the jumps, but it got stuck in that gear, It was super hard to accelerate under 40 mph. So I pulled over and tried turning it on and off but the van wouldn’t let me start it. I was trying to get it started again by opening the doors when I turned it off and eventually it turned back on, however, it remained stuck in gear all the way to the job (I use my van for work but I don’t max the payload. I was in a hurry to get to the job, and the transmission would not accelerate fast 😂) it smelled Burt all the way, so I was expecting my van not to turn on after my job was over, but if worked perfectly fine. And it has never done that super bad shift that it locks in gear. That’s the closest I’ve ever been to calling a tow truck, but 8th time starting it was the charm. My buddies thought I was purposely driving slow/ but I just couldn’t accelerate. My van is now on 165k miles and it still does the bad shifts and I tried taking it to the dealer about the transmission problem but “it’s a software issue” I thought they had their head in their a….

Before taking it in, I would try disconnecting the negative battery cable on the main the auxiliary (if you have auto start/stop). Let it sit for a few minutes without power, this will reset the sliding door modules. Reconnect the batteries and there is a good chance your doors will be back in operation.

My understanding is these transmissions have what are known as “dog” clutches. This was in a move to make everything fit in such a small size. I’ve been in a position to consider one of these years ago, but spoiler alert we decided not to. If anyone is wondering, in a clutch like this instead of using friction and reaction disks like a normal clutch it literally meshes two gear sets, or dogs. The main advantage of this clutch is rather than relying on coefficient of friction and pressure all you need to worry about is the strength of the metal-to-metal interface. The result is a clutch of maybe half the axial length not counting piston with a shorter tolerance stack up which helps further shorten the clutch. Sometimes you really do only need 5 or 10 millimeters. Cue this psycho idea. There is however a big down side to a dog clutch. When meshing the two sides of these gears together you HAVE to know the relative speed between them. This seems simple but if you have enough error in your speeds it is going to shift with a bang. I’m fairly confident that at least in the random hard shift department this is the problem. Whatever method they’re using to measure relative speed between or even position of the dogs isn’t good enough. The trim must be an attempt to overcome speed uncertainty but it could be pretty easy for something like that to go into wind up.

I think your summary is spot on, couldn’t use regular clutches and fit in 9 speeds. The interesting part is, the base tune is pretty smooth. The problem arises when the adaptions start happening.

Thanks for the videos. A few questions. 1) Do you think allowing only one driver will help since the TCM does not have to learn the habits of other drivers? 2) Once the TCM is reset can there be some initial hard shifts as the TCM re-learns? I ask because my son drove the vehicle the night before I did and it was hard shifting frequently the next day when I drove it. I reset the TCM, had a few minor bumps then it seemed to smooth out. I intentionally drove through the center of town with a lot of start and stops and had no issues. In fact, the shifts were fairly smooth for about an hour of driving. I then intentionally accelerated quickly and noticed a slight bump on the downshift. Seems like once it learns my driving habits I have to maintain those habits (slow, gentle accelerations).

@TheLawnEngineer

Жыл бұрын

I don’t know for sure because I’ve never studied the actual code used. But all of your points are valid. I have noticed a few less than ideal shifts directly after a reset and then smooths out. Also, it does seem to like slow smooth acceleration the best and different drivers can have wildly different styles. I believe the root cause of the issues on this system has something to do with the feedback sensors are giving the computer. They are either not accurate enough or don’t sample frequently enough to provide good direction to the computer. The computer then is making changes based on erroneous data and the mistakes add up over time compounded into an almost undrivable state.

have you had any problems with the auto/start stop? i went to start it one day and it wouldn’t start on the first attempt, dash lit up with all codes, once it started (on the second attempt) and since then it says the auto start stop is unavailable. it occasionally has a hard time starting. meaning when i hit the button it doesn’t start right up it’s kind of electrically clunky and takes a moment longer to start! but it always does on the first push. i have heard an occasional clunking sound in the engine and the rear brake assist is not available. i’m unsure if these are all related? would love your thoughts.

I just got a 2017 pacifica and as u say the trans acted a bit wonky so I took ur idea and did a reset. Better. Than I took it back to the dealer and drove around with a mechanic who used to rebuild transmissions. Of course the van performed performed perfectly for him. He explained the adaptive soft wear and told me I could try a reboot by disconnecting the battery and shorting the leads together and wait five minutes than reconnect and start it up. So I discovered the second battery and disconnected that also when I found there was still spark when shorting the main battery leads. So it seems good after a few days. What do u think?

These dealerships don't want to do warranty work. If you have a intermittent problem good luck they want to keep your vehicle to try and find it they say after a few days the cannot make it do it.

Like your home computer it starts to mess up and you do a restart or reboot and it works fine again. Or sometimes a system restore fixes the problem. If you have a problem like this they should do a reboot of the computer when you have a intermittent problem. It solved my problem with the fob not detected at times. After like 3 times taking it to the dealer and them keeping it a few days and not finding the problem. After the 3rd time I asked for a computer reboot. I stayed in the car they hooked it up to the computer that goes to the factory which tested everything. The lights would cycle, windows up and down, everthing you would use and some you never though of. It took about 30 minutes or so why the tech just sat in a chair. When it was all said and done it was a bad fob. They reprogrammed a new key fob and it fixed all the problems I was having. It was under warranty even. To get them to do this was like pulling teeth. The scan tool they could not find anything. That doesn't mean something is wrong when you have a intermittent problem.

I have done the TCM reset several times, but the hard shifts/low clunking noise remains. I might have to bring it into the dealer for the update. Thanks again fir this excellent explanation.

@@Mike_44 your welcome, thanks for sharing your experiences. I suspect Honda used a better/different control module. I don’t think it’s purely software, my leading theory is sampling rate on the transmission sensors is too slow, giving erroneous feedback.

@thelawnengineer HOW are they getting away with this. Shouldn’t we be able to file a lawsuit or something. I too have an 19’ limited Pacifica and not long after purchasing I took it back 2 times and they swore they didn’t feel anything. 3yrs later it still jerks turning corners every now and then. NOW, the door cable is the issue and I got it back from the shop and NOW THE SEAT WARMER CONTROLS HAVE DISAPPEARED AND MY BACK UP CAM DIESNT COME ON! I’m sicka the van

I can’t confirm that, 2017-2020 is the 1st generation of the new Pacifica. I suspect the issue was the capability of the transmission control module which usually doesn’t get updated until a redesign/refresh that happened for the 2021 model year. Chrysler may have updated it before the scheduled refresh because of this issue but I can’t find any info on that. I believe someone commented in my transmission reset video that they had the problem with their 2019.

Could you possibly shed some light? This is a bunny trail, from the shifting issue you had on your 2017. Your story of clearing the module and our issue with the TCM has me wondering if you might be on to a possible mitigation. We bought a 2020 Pacifica Limited, 79,000 miles, 35 days ago. Stalled at 30mph. It started up, in apx 15 minutes. Mechanic read the codes, said the TCM wasn't communicating well, with the other modules and shut down. He said the module connections on the battery were loose and tightened them. It stalled again 10 days later. The Chrysler service center was able to get codes, as it stalled for them. The computer codes, from the previous owner and since we bought it tell a story of a long-term problem. According to the computer history the mechanic (of the previous owner) reprogrammed the computer and it was sold to our used car dealer. The Chrysler mechanic said his educated guess was that everything pointed to replacing the TCM that all the other computer modules couldn't communicate with. This entire time I have been in contact with the dealer, from which we bought the van. Yesterday, with the latest update of long term stalling issues, covered up with reprogramming, and the mechanic's educated guess for a fix, they asked us to bring the van back to them. They are going to have their Chrysler guy look at it. Thank you, for your time and insight.

I believe they fixed this issue in 2020. The transmission control unit (TCU (trans. computer)) was the same from 2017-2019. It was changed in 2020 and has remained the same through 2022. I have not heard of anyone with an issue on 2020+, so I have to think it was a hardware limitation of the original TCU.

A 9 SPEED! HOLY $HIT my 1981 chevy creep van had 3 LOL My wife's 2017 pacifica has 90k and leaking oil , has vanishing coolant and has a random insane engine shaking on cold start once in a while! the oil leak im hoping is from the absolutely horrible oil filter cap and not something major. like the oil the coolant just vanishes , no puddles , and its not mixing with the oil (i know exactly what that nightmare looks like). i had to add coolant once a week for like 5 weeks or so , just over a full bottle and i havent had to add any in 2 months ?? really odd. the oil leak has been a minor on engine only but the other day we had the first driveway puddle in 3 years! i added 3/4 of a quart and miraculously there's no leak now LOL not even a drop on the cardboard. cars have souls or gremlins, something that makes them act up randomly.

Have you replaced the battery? You could try to disconnect the negative terminal of your battery for a few minutes to reset all of the vehicle's computers. I would also go through the fuses (they are under the hood by the battery) the air blower motor fuse may have blown. Unfortunately, it is relatively easier to cause electrical damage when jump starting a car. Hopefully it just a fuse.

You are 100% correct for most every transmission but this situation is slightly different. There is something wrong with the control system on this transmission. I suspect the sample rate for the feedback is not sufficient to accurate measure what's really going on the with transmission. The control system then adapts the parameters to erroneous data and shifting gets worse and worse. The control hardware is simply not good enough for this trans and that is why software updates can't fix it. I did the first fluid change on this trans and the fluid was nearly clear no clutch material.
