07 charger v6 wont move, like its in limp mode, will shift solenoid fix this? wont move in reverse. thinking shift solenoid, help.
07 charger, v6, 42rle transmission, Was told car was sitting for 2 yrs when i bought it, towed it home by rollback, went on test dr after putting in a good battery, everything worked perfect, parked it, then moved it again the same day, when i shift to R it wont go anywhere, heard a thump like its in gear, but wont move, flushed transmission fluid and filter, now wont go anywhere like its in limp mode, when i shift to drive hear a whining sound at first from transmission, don't have enough power to go up my driveway, was leaning toward transmission shift solenoid, fluid is full, check engi
Experienced mechanics share their insights in answering this question :
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.
How to Identify and Fix Common car Problems ?
Our sources include academic articles, blog posts, and personal essays from experienced mechanics :
You can attempt to bypass Limp mode by restarting the vehicle after a short wait or by removing one of the battery terminals to reset the electronic systems.
Limp mode is a car security feature that activates when a fault is detected, reducing speed and switching off non-essential functions. It is triggered by abnormal signals from car components, such as faulty sensors, transmission issues, or low fluid levels.
Also known as `limp home mode`, limp mode is a security feature, which is activated when either a vehicle`s engine control unit or transmission control unit detects a fault. It is designed to protect the engine and transmission from catastrophic damage or complete failure.
Transmission issues have plagued Charger owners for years. Numerous people have complained about gear slippage, intermittent hard shifting, and decreased acceleration. In a few instances, the Charger reportedly switched gears on its own.
Speed sensors, the MAF, MPS and TPS; to name just a few of the essential monitors within your engine. All of these send signals to the control units, so as with faulty wiring, if one of these monitoring units is not functioning correctly, then it could send a message that causes the car to enter limp mode.
The computer may have run out of the battery power used to store important information. If this isn`t computing correctly, the engine will sense a problem and trigger limp mode.
Can an O2 Sensor even throw the car into limp? If it`s throwing the code for the o2 sensor it won`t go into limp mode, since the ecu recognizes a problem with the sensor it disregards that input.
One of the most common reasons a car goes into limp mode is a problem with the fuel system. If the fuel pump isn`t working properly or there is a blockage in the fuel lines, the engine may not be getting enough fuel. This can cause it to run rough and eventually go into limp mode.
In modern cars, a bad catalytic converter can cause an engine to run lean by altering the fuel ratios and in some cases even cause them to go into limp mode.
No. When the engine or transmission control unit of your vehicle recognises a serious fault from the engine or transmission, many modern cars will force the vehicle into a `limp mode`. The aim of limp mode is to reduce the power output of the vehicle and limit the RPMs of the engine.
Transmission Range Sensor (TR)/ Transmission Position Sensor
The PCM uses this information to control which gears of the transmission to enable or disable. When the TR sensor fails it can cause wrong gear starts, no upshifts, or what feels like a falling-out-of-gear condition.
Generally this causes poor performance and limp mode, and customers often complain of a faulty MAP sensor despite the fact it just hasn`t been calibrated correctly, or at all.
In the case of the throttle body (and related sensor), delayed to false information can cause the computer to make faulty corrections to the air-fuel mixture. You might notice a switch into “limp-home” mode, where the power to the car`s engine noticeably reduced power is reduced no matter how hard you press the pedal.
Can a Bad Car Battery Cause Computer Problems? A faulty battery can have an impact on all of your automobile`s electronic components, including the car computer. If a malfunctioning battery is unable to provide the necessary electrical energy to a computer, it could result in issues.
Cylinders: If your battery is not functioning properly, the fuel injectors may not deliver enough fuel to the cylinders. This can cause a reduction in vehicle performance. Computer: A weak battery puts additional strain on the vehicle`s electrical and mechanical systems.
Turn off your vehicle`s ignition and wait patiently for 5 to 10 seconds. Start the engine and allow it to idle for several seconds. Switch off the ignition and wait patiently for another 30 to 40 seconds. Repeat these steps 2 to 3 times in order to reset your vehicle`s transmission control module.
Power on the device and wait for the status led to stop flashing (or go into failsafe mode, as described above). Press and hold the reset button for 10 seconds. Release the reset button.
You can bypass limp mode by restarting your car, checking the fluid levels, disconnecting the battery, or scanning it with an OBD scanner. When limp mode is active, you should avoid driving unless absolutely necessary. Avoid highway travel and take routes that are less traveled.
The code P0420 (https://www.yourmechanic.com/article/p0420-obd-ii-trouble-code-catalyst-system-efficiency-below-threshold-bank-1-by-jamahl-walker) will cause the computer to put the transmission in limp mode to protect the catalytic converter.
While the damage may seem small initially, the longer you drive with a bad oxygen sensor, the worse the damage will become. Eventually, you may experience rough idling, poor acceleration, engine misfires, an illuminated check engine light, and failed emission tests.
A faulty EGR valve can result in excessive carbon/soot at the turbine end of the turbo charger. This could cause the VNT mechanism to become clogged and stick which in many cases will cause engine management lights to appears along with reduced performance known as “limp mode”.
Driving with A Failed Catalytic Converter
If you`re noticing slow powertrain performance, reduced acceleration, a smell of rotten eggs or sulfur from the exhaust, dark exhaust smoke, or extreme heat from under the vehicle, these are symptoms of a clogged Catalytic Converter, and it should be replaced quickly.
For example, in some situations an oxygen sensor can cause poor shifting in your transmission – if the engine isn`t running correctly, the transmission control module may misinterpret when and where it`s supposed to be shifting, causing erratic behavior at the transmission.
One of the most common check engine light codes that is associated with a faulty O2 sensor is P0420, usually displayed with the message “catalyst system efficiency below threshold.” Typically, this means that the O2 sensor is not reading the air-to-fuel ratio correctly, and it thinks that the catalytic converter has …

I shifted the lever to drive mode, but it goes to reverse mode. What is the problem?
ANSWER : You are very nearly right. There is a bowden type cable that connects the the shifter to the transmission. It has adjustable ends and one or more of those adjustments has probably worked loose. That or you might need a new shift cable or new bushings at the connections. Either way, you can have the problem conveniently solved by contacting Your Mechanic. They will send a technician to your home or office to check out your shifter and transmission and tell you exactly what you need to repair it. Meanwhile, be very careful with this car, it might not go into park when you expect it to so be sure to set the brake and park it very carefully.
why wont my `06 chevy tahoe shift into drive and go but when in park and shifted to reverse it will reverse?
ANSWER : Hi there. A car that refuses to shift or go into gear easily is trying to tell you something is wrong and in most cases the culprit is the clutch (in a manual transmission) or torque converter (in automatic transmission). Transmissions are very complicated and have many moving parts, ignoring a hard to shift issue can quickly spiral into a very expensive transmission repair. Over time, especially as a vehicle goes over the 100,000 mile mark, parts and gears inside the transmission simply wear out. This process can be dramatically accelerated if the car is driven with low levels of transmission fluid. The transmission will have to be rebuilt or replaced which is a very expensive repair. Symptoms of a failing transmission include hard shifting, humming, clunking or grinding. It might be best to have one of our professional mobile mechanics come to your location and complete a car is hard to shift inspection, so they can determine the best course of action.
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.
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.
Car turns on, able to shift but wont move
ANSWER : Great description. It sounds like you have a problem with the shifter cable. The cable either broke, or the end of it popped off. The cable runs from the shifter to a linkage arm on the transmission. The ends of the cable are plastic, and snap on to a steel ball. Wear on the plastic, or rust on the ball and it can come off.
The transmission range sensor is on the transmission. The fact the the indicator says "P" and you cannot roll the car supports this theory. I would have this repaired on the spot, or have the vehicle towed to get it repaired. A knowledgeable mechanic may be able to manually put the car in drive with you sitting in it, but do this as a last resort. You would not be able to put it back in park or reverse when needed, or restart the engine if it were shut off. The tow truck driver will need to manually take it out of park too if you decide to go that route. Alternatively, a certified technician from YourMechanic can come to your car’s location to inspect the shifting issue and assist with resolving the problem.
Alternator belt got torn whilst driving and had new belt fixed but the car won’t move on drive or reverse after few seconds drive
ANSWER : This is a sign of a faulty transmission control solenoid. Modern automatic transmissions use pressurized hydraulic fluid to change gears. Every time a gear change is required, the car’s computer activates a transmission solenoid, which directs transmission fluid into the valve body to engage the correct gear. When this is faulty or not working properly, this can cause a delay in gear shifting or in some cases cause the car to not shift at all. If you’d like, a certified technician from YourMechanic can come to your home or office to inspect your vehicle, and provide a definitive diagnosis for the shifting issue.
When shifting from reverse to drive or drive to reverse I hear a clicking noise.
ANSWER : Hi there. There is a gear train issue with your transmission or a bad CV Shaft that is causing the transmission to shift had into gear. Since it shifts harder in reverse than forward, I suggest that the gears inside the transmission are worn. I recommend seeking out a professional, such as one from Your Mechanic, to help you diagnose your transmission issue.
