Hello. The most common problem with the use of a shade tree mechanic is they tend to use substandard parts. Cheaper parts often lead to expensive repairs. This concept is easy to sell if you explain the likely hood of a cheaper part to fail and require the repair to happen again and your, the customer will again be left on the side of the road.
The inside of transmissions have wires that become brittle because of there exposure to ATF. (automatic transmission fluid). It is very easy to damage these wires as well as there is a high potential for pinching said wires. It is very common for there to be wiring harness issues that look like there is a component problem. In the act of replacing the solenoid, this condition may have been made worse. What needs to happen next is for someone to do some sound diagnosis and to double check the repair. Regardless of who had done this repair, I believe that this should be double checked. A diagnosis of the shifting problem will require a scanner, wiring diagrams, an experienced technician and a test light.
How to Identify and Fix Common car Problems ?

Shift solenoids can be somewhat expensive to replace, but not nearly as much as the entire transmission. Ignoring a warning light or code being thrown by a faulty transmission shift solenoid can lead to serious problems, such as running your vehicle in the wrong gear for your speed and conditions.
Shift solenoid B allows the transmission to shift between 2nd and 3rd gear. When the powertrain control module (PCM) records code P0758, it indicates that the PCM is unable to detect the proper change in engine speed or increase in ground speed that should occur during a 2nd to 3rd gear shift.
What Are Some Causes of a P0751 Code? This code indicates that there`s a malfunction with the shift solenoid “A” shift circuit. Most commonly, this is because of low transmission fluid, dirty transmission fluid, or a clogged transmission filter.
On regular solenoid valves, it can be switched back to the operating position by energizing the solenoid, while on solenoid valves with latch-lock function it will not be so. After being energized, the valve must be manually reset by pushing the reset-knob.
Yes. There VIN number of the vehicle must be programmed into the new ECU. If it`s a factory ( OEM ) replacement, the whole ECU must be programmed. The new ECU won`t know a lot of stuff about the car until it`s programmed; things like, which engine is installed, which transmission is installed and many other things.
But a blown fuse No. 38 becomes a likely candidate causing a loss of power to the transmission solenoids.
If your car has an automatic transmission, the shift solenoid will shift the gears for you. The transmission control unit will take the information from the engine and speed sensors along with other parts of your vehicle to then decide when to shift gears for power and fuel efficiency.
This code triggers when the PCM detects the “B” shift solenoid circuit has a malfunction. But the code can also be triggered or associated with several other transmission-related problems such as the following: Low or dirty transmission fluid. Clogged transmission fluid filter.
For example, a single transmission shift solenoid can cost anywhere from $15 to $100. A solenoid pack, which includes all the solenoids for a particular vehicle/transmission can cost from $65 to several hundred dollars or more.
P0741 is a diagnostic trouble code (DTC) for “Torque Converter Clutch Circuit Performance or Stuck Off“. This can happen for multiple reasons and a mechanic needs to diagnose the specific cause for this code to be triggered in your situation.
Residual Magnetism. Even after a solenoid is de-energized, magnetism may remain in components with low magnetic permeability. This can cause the plunger to stick.
P0777 code definition
A P0777 trouble code signifies that the Powertrain Control Module (PCM) has detected a fault in one of the electronic pressure control solenoids or solenoid circuits.

07 charger v6 wont move, like its in limp mode, will shift solenoid fix this? wont move in reverse. thinking shift solenoid, help.
ANSWER : The check engine light could mean diagnostic codes related to the transmission failure are available. If you request a check engine light diagnostic a mechanic could see if relevant codes have set and narrow the diagnostic for you. Check to be sure that there is adequate fluid. Check to be sure that the manual lever (shift lever) on the transmission reaches the correct position when you select "D" or "R". If you can’t move in any gear, the problem is not likely to be the solenoids because failure of the solenoids will still allow operation in "some" gears, if the gear is manually selected. If the solenoids failed, such would also result in a code being output because the TCM performs continuous circuit integrity testing on the solenoids. You can test that part separately in any event. There is a 164 page repair manual, with all the diagnostics, that you can use to pinpoint and repair the issue. However, if you just want a diagnostic, you can request a transmission diagnostic – failure to shift and the responding certified mechanic will pinpoint the issue. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.
My mpv gave a code Shift Solenoid Stuck On just replaced solenoid a and b still dont work . wont drive
ANSWER : Return the vehicle to the shop that replaced the shift solenoids and have them check again. Most reputable shops provide a brief warranty on their repairs. If the repair was made by you, double check all the electrical connectors, on the transmission to make sure they are all plugged in fully. Also make sure you have the proper amount of transmission fluid. Your shifter linkage could also become misadjusted during repair. If the vehicle lurches forward in gear but doesn’t roll, you could have a parking brake issue. Check for trouble codes with a scan tool, If you have any codes, it can help point you in the right direction.
If the shop can’t help you repair this or if you’d simply like a second opinion on this, consider YourMechanic, as certified technician can come to your location to diagnose your no drive symptom and help you repair it accordingly.
My gear shift doesn’t shift to any other gear its stuck on neutral. I open the gear assembly and I can pull a lever which allows me to move it.
ANSWER : Hi there. The shifter interlock solenoid is not working and needs replaced. The shifter interlock solenoid makes the shifter lock in place so it does not move if you accidentally move it into another gear. If you need further assistance with your shifter not working, then seek out a professional, such as one from Your Mechanic, to help you.
Car in park shifter will move through gears but wont shift through the gears its stuck in neutral have emergency brake on so it wont roll
ANSWER : From what you’ve described, it sounds like the shifter cable came off at the transmission or the shifter. I’d suggest checking the shift linkage on the transmission to see if the cable came off. This is due to the connector end bushing falling apart and not being able to hold the cable on any longer. Some cables have to be replaced as a whole and as with others the bushing can be replaced to fix the cable. I’d suggest contacting a certified technician, such as one from YourMechanic, who can come diagnose your shifting issue and make the necessary repairs to your vehicle. Good luck.
2003 jeep liberty stuck in reverse, shifter is stuck…but crawling under and trying to manually shift from transmission stuck
ANSWER : Hi there. Based on what you have written above, it is highly probable that the inner linkage has come loose or there is an obstruction within the inner gear set that is causing your problem. Unfortunately, this typically requires dropping the transmission and repair or inspection from the inside. This is not a service our mobile mechanics are equipped to offer, so your best bet is to contact a local transmission specialist for assistance.
Wheel locked, brake pedal wont go down, shift wont move and ignition wont turn?
ANSWER : Hello. You are likely experiencing an engine failure of some type. Do not let this scare you at first. All of these systems that are failing depend on the engine functioning correctly in order to do their job. Without vacuum you will have a hard brake pedal. Without pressure to the power steering system you will not have assisted steering and it may feel like the wheel is locked. The ignition will also depend on having an electrical connection for the sensors to work correctly. Did you notice this when you went to start the vehicle, or did this happen when you were driving? If you discovered this when you went to start the vehicle, check the battery and ground connection first. If this happened while driving then you will need to find the reason your vehicle stalled.
hi my passager front door wont open and the outside wont open to how can i open it
ANSWER : Hello, thank you for writing in. The determining factor in opening the door will depend on what is obstructing it. If the handle is rendered unusable, then you will have to access the inside of the door panel while the door is closed. It is difficult to carefully remove the panel in tight quarters, but typically it can be done without any damage. Once the door panel has been removed, you can access the handle and latch from the inside. If the door is obstructed by the vehicle itself with physical body damage, this body damaged has to be reversed or removed. Find the obstruction and eliminate it, or access the door latch from inside the door panel. For more help opening the door and resolving the issue, contact our service department.
