Pitman Posted September 21, 2016 Share Posted September 21, 2016 Hello all. New to the forum so if this has been discussed already I apologize. I have a 2010 fusion sel 4cyl with 82k miles. The transmission slams when engaging into reverse or drive, and is stuck in 2nd or 3rd (not sure which) when driving, and the engine light is on. You can reset the computer and it does fine for a little while, then the engine light comes on and it starts doing the same thing again. I initially changed the transmission thinking it was just a bad tranny, but this one does the exact same thing. Any help is appreciated. Thanks 0 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 21, 2016 Share Posted September 21, 2016 Were new TSS/OSS sensors installed with the "new" transmission? If not, that could be one reason. Low fluid level could cause these issues also. Finally, it's possible the calibrations for the PCM and TCM need to be updated, ask the dealer to see what might be available. See the TSBs related to your Fusion here: http://www.revbase.com/BBBMotor/Tsb/Results?Year=2010&Make=54&Model=2816&AbSystem=a71 0 Quote Link to comment Share on other sites More sharing options...
Pitman Posted September 21, 2016 Author Share Posted September 21, 2016 I didn't replace the sensors since the new one worked fine in the donor car with only 50k miles 0 Quote Link to comment Share on other sites More sharing options...
WWWPerfA_ZN0W Posted September 21, 2016 Share Posted September 21, 2016 ok, this is first hand knowledge? Then recalibration and fluid level check should be the next objectives. 0 Quote Link to comment Share on other sites More sharing options...
drolds1 Posted September 21, 2016 Share Posted September 21, 2016 If you have a CEL, haven't you pulled the code to see what it's trying to tell you? Clearing the code is treating the symptom, not finding the cure. If you have the same symptoms with two different transmissions, apparently, the transmission wasn't the problem. I'd suspect the TCM or even ECM but without the code, you're just guessing and throwing parts and money at it. 1 Quote Link to comment Share on other sites More sharing options...
Pitman Posted September 22, 2016 Author Share Posted September 22, 2016 Scanned it last night. Code is P0657 (actuator supply voltage circuit open). Cleared the codes after that and it works perfect.....until next time. It says the possible culprits are a faulty ecm, faulty ecm connection, or ecm needs updated. Voltage to all transmission solenoids have been interupted. Anybody else ran into this? I'm gonna start with the local ford dealer and check for updates 0 Quote Link to comment Share on other sites More sharing options...

ATX-Mike Posted July 15, 2018 Share Posted July 15, 2018 (edited) I had something similar end up happening to me however mine ended up being a forward clutch hydraulic leak and I needed a new transmission installed (covered under extended warranty) but now will either over-rev in 1st to 2nd or over-rev in 4th to 5th with the latter being 9/10 times.

mga Posted August 13, 2020 Share Posted August 13, 2020 any updates to this issue? im have the same problem with my 12 ford fusion 3.0L The transmission slams when engaging into reverse or drive sometime, but when i restart the car it work fine for little bid but it dose the same thing agin. The engine light is on when scanned code PO657 comes up. I initially changed the transmission because the one was on the car was bad. Any help is appreciated.

bbf2530 Posted August 13, 2020 Share Posted August 13, 2020 Hi mga. There are multiple possible causes. If you Google "DTC P0657" (i.e. it is a zero "0", not an uppercase "O"), you can find articles pertaining to DTC's, what they mean, how to diagnose, etc. You can begin your troubleshooting here: https://www.obd-codes.com/p0657 Or here: https://www.troublecodes.net/pcodes/p0657/ Or here: https://www.engine-codes.com/p0657_2012_ford_fusion.html Let us know how you make out and good luck. 0 Quote Link to comment Share on other sites More sharing options...
Pitman Posted August 13, 2020 Author Share Posted August 13, 2020 Hello mga. I feel your pain. I was the original poster on this topic several years ago. Mine ended up being a bad connection where the computer plugs in at the firewall. I unplugged it checking connections and noticed one of the pins were bent on the male end causing damage to the female end. Straightened that up and it has been fine for several years now. Lesson learned, wasted a few evenings swapping out a good tranny when all that was wrong was something as simple as a bad connection. Was able to sell the tranny I pulled out to recoup my money. Let us know how it goes 0 Quote Link to comment Share on other sites More sharing options...
TLK914 Posted January 18, 2022 Share Posted January 18, 2022 This sort of code should be approached by its description (most all codes actually, but we will stick to this here) The codes states that power was lost to the solenoid pack, all solenoids at once. Note that the power is individual feeds from a common source inside the PCM. SO, the primary checks will be - 1 : Does the PCM power supply from the fuse have battery voltage and is it reaching the PCM connector? Start by locating the fuse itself and checking for voltage (Perfectly good fuses that have no power to them are still seen as blown by the PCM/component, so dont do a visual fuse test, verify power!). If you have 12v at the fuse(both sides!), and also 12v at the PCM connector downstream of the fuse, then youdont have a power supply issue to the PCM. At this point the next test as also at the pcm connector (Easy since you are already there). test any solenoid output feed from the pcm for battery voltage. They all get it, see if its coming out on one or all. Likely you will have all acting the same, all will have it, or all wont have it similarly. If all DONT have it, tested at the pcm plug, you have pretty much verified an internal PCM problem (Double check source voltage inputs and grounds. Voltage check the grounds especially). If all HAVE voltage, then you know the PCM tried to do its job, and it didnt see signal return. IE It sent power on the bat line to each or all solenoids. When activated, it measures to see if the voltage came back on the return side. If it sees continuity (through the solenoid) its happy, if nothing comes back, it sets a circuit open fault. At this point, since you are dealing with multiple (more than 5!) solenoids all with their own wiring, the odds of all solenoids breaking down internally and going open circuit at the same time are impossible. You need to check connectors for common issues. There is a connection at the trans, and another at the solenoid pack inside connected by the lead frame (piece of plastic with wire straps built in for its connections, think of it like the circuit board paper on the back of an instrument cluster with copper "wires" laid into the paper). if the lead frame cracks (they do that when they get old) it could take out multiple circuits at once. Also, circuit 50 (it varies by year) for the f35 can go open internally in the PCM and end up with the same problem. Check your wires as above, then determine if the power leaves the pcm to head for the solenoids. If it makes it to the trans, you can then pin check your solenoids 1 at a time for proper resistance. if they have correct resistance at the trans connector, then the problem is either open pin 50 on pcm circuit, or internal pcm problem. If solenoids show no resistance, or even 1 or 2 of them show open circuit...rhe problem is more likely your lead frame internally has failed. remember, a single bad solenoid sets a code for itself. if you get the 657 code, your PCM is saying all the solenoids did not return a signal when e xpected All the above testing can be done with a multimeter. Labscopes or OE scantools not needed. Hope it helps 0 Quote Link to comment Share on other sites More sharing options...
TLK914 Posted January 18, 2022 Share Posted January 18, 2022 OK...that didnt take long. A friend no less already calling for specification. OK. Take a look at this. This is off a 2014 I think it w as a transit, but still an F35 trans with similar design flaws and choices. It is a blurry mirror shot on a transit. look at the mirror image, you will see blurry yellow pinholes, but one, almost dead center is BROWN. THAT little brown mess had them bang out of gear and come to a stop, towed it to a reputable transmission shop who determined internal wiring malfunction, rebuilt the whole tranny because it had over 150k on it, tested it, all good, delivered it, did the same thin 2 hours later. Replaced the solenoid pack, the lead frame, and tried again. Wouldnt get off the lot. Remanded it to me (Im the company computer/electrical geek, I work at a different location). I tested power on blue and green wire at the trans plug which as it happens is that little toasty pictured one. It had 12.5v there when the code was resettig immediately. So I know right there PCM is OK, fuse is OK, and power up to connector was OK. removed connector and tested at the female pin. 12.5v. OK, power reaching the trans, absolutely. UNLESS we have bad pin tension. The other shop already had 2 valve bodies and solenoid packs, and 2 lead frames, genuine Ford parts. looking at the trans connector you see a black connector with a bunch of silver pins...visually FINE. Or at least you can see anything wrong staring at the harness connector. SO, I threw the mirror up, saw this, and then took a blurry pic because I was on my back under the car, holding a flashlight a camera and a mirror while looking up and trying to aim and stay steady. You get what you get. This is how *I* chase circuit codes. Wiring diagram 1st. code was for all solenoids, so its a common power or common ground problem. They all share common power on diagram (Blue green wire pin 51). Now you know where the problem HAS to be. but could be a blown fuse (not really, fuse feeds more than just the solenoid pack so woulda probably set other faults). But fuse was OK. Checked power at connector and here we are. COULDA checked ower at PCM, or power on an exposed portion of harness because its much easier and seems faster, BUT, that only is part of the picture. If I check 3 feet from fusebox and have no power, great Ive found the probem is between good tested fuse and the test point 3 feet away there is a break in the wire. But if I test 3 feet away and its got 12v, I know its not bad there...but still dont know if its a PCM, a broken wire, a bad trans plug, or whate ver because I used time to test too close to answer more than 1 question. Instead I chose to remove the fender liner and the belly pan, and test the trans 1st as thats farthest away and if I get an answer there, then many components upstream are already verified and it saves rechecking at multiple points. Im not saying yours will be bad pin tenstion. Im saying it COULD BE. Or it could be 10 other things. Testing is what tells you. HiH.
