  1. Cvt Fault Facts Request.

    Hi Thanks for your reply to me, for some reason i can't follow the link to answer you direct. So I'm happy to add the answer here. When I changed the oil, I did remove the sump, and change the filer, and clean everthing. With the sump off i checked the electrical connection to the CVT unit, all looked in good condition. Below the ======= is a slightly longer version of the problem. I've covered approx 10,000 miles since this started, about a week after buying the damn thing! (smile) and it does not appear to have developed. So it's about the same now as it was! I do find that by holding the engine RPM slightly high when at a standstill(traffic lights) definatly helps. This indicates that the CVT unit oil pressure is dropping below a value, the oil pressure sensor see's this and sets the codes. sadly the new correct from Ford oil did not help or change my problem. I hope this helps, and more than happy to help if i can. If anything changes I will update the post. Sorry for going on abit, hope it helps. Best regards John ==================================================================================================================================== FORD C-MAX 2005 MY SA05DPE Mileage, 659889 The car has a very intermittent problem. Under normal driving the car and transmission works well. However, when coming to a stand still, very intermittently, the Transmission Malfunction warning message comes up on the dash. If you try to pull away, there is a delay, and it’s as if you are starting off in 2nd gear. Also the gear selector lever goes stiffer than normal, with it very difficult to select another gear (Reverse) However, by turning off the engine and restarting, the fault message is deleted and the transmission works correctly. There are no factors I can see that triggers this, Temp, weather condition, speed, duration of journey, etc! apart from the car coming to a standstill for a few seconds. There were 3 fault codes set in the Transmission Control Module, P0701, Transmission Control System Range/Performance. P0961, Pressure control Solenoid “A” control circuit Range/Performance. P0871, Transmission Fluid Pressure Sensor Switch “C” Circuit Range /Performance. The way the car reacts when the codes are set, indicates the system going in to "limp" mode. So the "fault" could only last a few milliseconds, but it's the Limp mode is what you experience! I have changed the transmission fluid and filter in the Trans sump.
  2. Cvt Fault Facts Request.

    Hi This is John R. I have a c-max with an intermittent cvt problem. 2005 1.6 CVT It only occures when the car is standing still, traffic lights, etc. then the "transmission Malfunction" message appears. Turning off the engine and restarting, clear the message and the car operates correctly until the next time. It is intermittent with no pattern to when it will occure again. The fauts codes set are: P0701 TRANS CONTROL SYSTEM RANGE. P0961 PRESSURE CONTROL SOLINOID A CONTROL CIRCUIT P0871 TRANS FLUID PRESSURE SENSOR/SWITCH "C" If i keep the rpm slightly above idle the problem is less likely to occur! It appears that the oil pressure maybe dropping below the required level when idling. Keeping the idle speed up helps to reduce this. I've worked in a motor companies (Volvo)technical dept for many years before retiring. So have some technical knowledge of how things work. Ive changed the oil and check the basic electrical connections to the CVT unit. Sorry for expanding more than just the codes, but some back ground might be useful. Happy to dicuss in more detail if required. Regards John R.
  3. Cvt Trans Fluid

    Hi, Pavillion, Thanks for your information. In the end I decided to use the ford fluid as you are not able to remove all the existing fluid, I felt it was better not to mix them. However, making sure you got the correct fluid even from a Ford Dealer was not the easies thing, the first dealer sold me some "normal" ATF but was confident it was correct, it was not!! But in the end I did get the correct fluid Part No 1699670 spec M2C928-A at approx £20 a lt!!!! liquid gold!! So if anyone else is planning to do this, insist that the spec is the correct one!! I did replace the filter in the sump, and checked the wiring and connections within the sump area too, all looked good! I also drained the fluid through a filter and found NO large deposits. Fairly straight forward job, I used a syringe to refill the fluid, it took awhile but worked well. The car has a very intermittent problem. Under normal driving the car and trans works well. However, when coming to a stand still, very intermittently, the transmission malfunction warning comes up on the dash, with a hash gear selection if you try to drive away, also with the gear selector goes stiffer! if you try to select reverse, the movement is stiffer! However, by turning off the engine and restarting the fault message is deleted and the trans work correctly. There are no factors I can see that triggers this, Temp, weather condition, speed, duration of journey, etc! There were 3 fault codes set in the control unit, P0701, trans control system range /performance. P0961 Pressure control Solenoid A control circuit. P0871 Trans fluid pressure sensor/switch. The way the car reacts when the codes are set, indicates the system going in to "limp" mode. So the "fault" could only last a few milliseconds, but it's the Limp mode is what you experience! But exactly what is setting the code is still a mystery. If anyone has experienced the same fault, with the same codes, and found the cause, I would appreciate the feedback. As I have not found a solution, this may not be help much. But hopefully a solition is out there somewhere? Thanks, John R
  4. Cvt Trans Fluid

    Hello, I've got a 2005 C-max, 1.6D CVT. I was planning to change the CVT fluid. Does anyone know of a correct alternative fluid other than the Ford product? I want to use the coorect fluid, but if there is one at a more reasonable price it would be appreciated. Thanks for any help or advice. Regards John R.
