It would have been helpful at this time to know the conditions required to set code P1702 and the related diagnostics. If we can't warranty it we don't sell it. Shift Solenoid 'C' Intermittent P0765. Not being any further ahead and just as blind to the problem as they were before hooking up their scan tool, the decision was made to locate a scan tool that could communicate with the vehicle. Early detection can result in minor repairs or adjustments; a considerable cost savings from more expensive repairs due to driving under incorrect pressure and causing more damage. Pressure Control Solenoid 'C' Stuck On P0798.
Instead, the solenoid is replaced. Testing the transmission line pressure is one proactive step that will alert you to potential problems. This portion of the test must be done precisely in order to not permanently damage the transmission. Check out our step-by-step guide on how to diagnose and repair a. Most of our product have a 1 year warranty but check the listing or ask us.
This article applies to the F-150 2004-2014 and F-250. On far too many occasions we hear of shops that have changed the solenoid body and replaced the wire from the computer to the solenoid, yet the code remains. We intend to make an internet site beneficial for many people. A correct diagnoses of a transmission problem when there is no check engine light is best accomplished with a professional transmission scan. A code P0960 will be stored when the transmission control module sees a fault with one of the valves, including a voltage signal stating that the A control circuit is remaining open, or not receiving the reference voltage needed to operate. After we did, when the ignition was turned on, we had 5. When diagnosing solenoid-related problems with automatic transmissions, it has become increasingly imperative to pay strict attention to detail.
Attaching the hose to the fitment after the fitment has been inserted into the port hole will make sure that if you strip any threads, it will likely be the fitment threads at the female end. The difficulty for the shop at this time was that their aftermarket scan tool did not offer Daewoo support. Learn how to make your truck back up properly. You should thread the fitment into the testing port first, and then the hose into the fitment that is in the testing port. Park on a flat, level surface with plenty of space. I'm proud to say I'm a 2nd generation transmission re-builder and transmission tech. Pressure Control Solenoid 'A' Performance or Stuck Off P0747.
Transmission line test port locations 5r110W top, 6r140 bottom. Replacing the line or draining and replacing the transmission fluid may be all that is needed. It is standard procedure for the shop making the repair to waive the diagnostics fee. If it is slightly dirty or reads low take the reading while the engine is hot , consider draining and replacing the fluid or adding more if it is the correct color and just low. Customer Satisfaction:Our main goal is 100% customer satisfaction and 100% feedback score. Within the 5R110W transmission there are seven solenoids: four shift solenoids with the same part number, a coast clutch solenoid and a direct drive solenoid which have the same part number, and one line pressure control solenoid with a different part number seven total solenoids but only 3 part numbers.
The failure of this solenoid can also cause the transmission not to shift to the next gear or any gear, which means the vehicle will not move when the transmission is put into gear. It should not be much, but it must be wiped clean before continuing on to the rest of the test. Once the integrity of the circuit is confirmed, a malfunctioning computer can be pinpointed as the problem with confidence, regardless of how many refurbished units were used. Otherwise, you may need help from a second person holding the gauge to give you the readings. This 5R110W Torque Shift Transmission is out of a 2008 F250 crew cab with a 6. These are Ford solenoids rebuilt by us in house.
This indicates a serious transmission problem which will likely require a rebuild at best. This is because the control module pulses the solenoid longer with a high duty cycle to reduce line pressure ~70-80% on time and shorter duty cycle to increase line pressure. Compare your actual pressure settings with the correct range from the manual. This is because many of the refurbished computers are bad as well. All but one solenoid can be replaced without removing the valve body. This article will cover some of the ways you can diagnose and. All things electrical begin and end with the battery.
As soon as the vehicle was started, the code appeared for a couple of seconds and disappeared into history. A look into history codes, however, revealed a P1702 Torque Converter Clutch Circuit Malfunction. Since the computer pulse width modulates these solenoids under normal conditions, the circuit never pulls this type of amperage. A bad or failing transmission pressure control solenoid can cause slipping, which can result in the transmission overheating. Shift Solenoid 'D' Stuck On P0768.
The decision was made to quickly unplug the vehicle harness from the transmission to see if the short was in the transmission or in the vehicle harness. Torque Converter Clutch Circuit Electrical P0744. Shift Solenoid 'A' Intermittent P0765. This causes all kinds of problems by affecting the movement of the solenoid's plunger. I do not sell any product that I would not use on my own rebuilds. Shift Solenoid 'C' Stuck On P0763.
The results of the gathering are published on this site. A slipping transmission can be a bad sign for your vehicle and it's something that needs to be diagnosed immediately. Since the code was set in history, it was erased with the idea to drive the vehicle to see when the code would actually set. On many of these systems high line pressure is the result of an unplugged or damaged circuit leading to the solenoid. Intermediate Shaft Speed Sensor Circuit P0792.
