Connector that links shift lever to transmission disconnecting

The connector that links the shift lever to transmission, disconnects when changing from reverse to drive. I am able to reset the unit onto the toggle that changes the gears, but it does not stay on when parking.
Experienced mechanics share their insights in answering this question :
Hello. If the shifter cable is popping off of the transmission selector sensor, then either the end of the cable is worn out or the selector is bad. Most of the time the cable end is where the problem is and the shifter cables needs to be replaced. A mechanic would typically install the cable and install it and see if the end is broken and then replace it. I would have your transmission inspected by a professional mechanic who can point you in the right direction for repairs.

Shift Linkage refers to the car cables that connect the gearshift or gear selector to the transmission. Gear shift linkage, shifting linkage and transmission shift linkage (transmission linkage) are related terms.
Ensure that the end lines up exactly with the matching section of the selector lever. If you notice any misalignment, you can adjust the linkage. Typically, you`d only need to screw a threaded part in or out. Try reconnecting the linkage, then check if the transmission is working properly.
Unusual sounds can indicate bushing problems as well. With bushings, thumping, bumping, squealing, and whirring sounds are most common. This indicates a problem with the shift linkage, and that problem could be a worn bushing. Finally, transmission fluid leaks can indicate a problem with the bushing.
A torque converter is a large doughnut-shaped fluid coupling (10″ to 15″ in diameter) that is mounted between the engine and the transmission. It consists of three internal elements that work together to transmit power to the transmission.
Shift Lock Cable functions to prevent accidents caused by shifting of gears in a state where the brakes are not actuated by the driver`s careless operation in an auto transmission vehicle. A cable functions as a safety device that prevents the gear from being changed at the “P (parking)” position without braking.
Housing comes in two common diameters: 5 mm or 4 mm. 5 mm was once very common, and is more rigid and resistant to bending. It will typically have a larger inner diameter giving the cable inside more wiggle room. Currently 4 mm is the most common housing size for shift housing.
Technically speaking, yes you can drive a car with a broken shifter cable but it is not recommended. Driving with a broken or failing shifter cable is dangerous, hazardous, and unpredictable at best.
The gearbox linkage transfers movement of the gear stick to the gearbox, allowing gear engagement. We stock high-quality gearboxes and linkages for all cars. In a sense, the gearbox is the intermediary between engine and wheels. Its job is to optimise the engine`s rotational speed to achieve the desired road speed.
If the shift selector cable is going bad, the indicator light or cable will not match the gear you are in. For example, when you move from park to drive, it may say you are in park. This means the cable has stretched to where it doesn`t move to the correct spot and the incorrect gear noted.
The difference between the two is that the shift linkage is made of two fixed rods and the shift cables consist of two Steel cables.
Binding: Binding shift linkage or a binding shift lever can result in difficult or no shifting. The same is true for the shift rails located inside of a transmission. These shift rails have detent springs/pins that can stick, leaving a vehicle unable to shift.
An automotive clutch is used to connect and disconnect the engine and manual transmission or transaxle. The clutch is located between the back of the engine and the front of the transmission.
The input shaft is connected to the engine via the clutch, such that when the clutch is engaged, power goes straight from the engine to the input shaft of the transmission, and the crankshaft and input shaft rotate at the same speed.
The shift interlock solenoid is an important safety feature on your vehicle. It keeps you from shifting out of park unless the vehicle is in the on position and the brake pedal is depressed. If the vehicle will not shift out of park, chances are the shift interlock solenoid has gone bad.
A transmission shift cable (also called a shifter cable or any of the names listed above and even others that we may not have yet heard), is the link between the shifter handle and the transmission in a vehicle.
You can`t mix and match gear cables and brake cables – you need the right set of inners and outers for each job. Using gear cables for brake cables is exceptionally dangerous and you should never do it. You run the risk of them snapping at the worst possible moment, with potentially very serious consequences.
If the cable or housing has become kinked, worn, frayed or corroded, you may experience slow shifting, inconsistent shifting, hard shifting or no shifting at all. Replacing your cables and/or housing can improve shifting performance. When replacing shift cables, it can a good idea to also replace the housing.
The transmission is connected to the engine via a torque converter (or a fluid coupling prior to the 1960s), instead of the friction clutch used by most manual transmissions and dual-clutch transmissions.
Link transmission rate (Data Transmission speed) is the number of bits per second that can be transmitted. Propagation speed is the speed at which a bit (signal) moves through a medium. It generally is within the range of 2×10^8m/s to less than the speed of light ( 3×10^8m/s ).
It really depends on whether the pin itself is damaged or if the shift linkage or shift cable is damaged. If it`s a minor repair, budget $200 to $350 for most local shops. If it`s replacing the shift linkage and cables, it might be closer to $500 in most cases.
The driveshaft itself is enclosed in a tube. Torque tubes connect the transmission and differential via a single universal joint, or U-joint for short.
Over time, dirt, debris and other tiny particles can accumulate in the transmission fluid, affecting its fluid properties. This can cause the vehicle to die when you shift into drive or reverse, allow a loss of power, transmission slip, rough shifts or even prevent the vehicle from shifting into gear at all.
Common causes of transmission solenoid failure include: Electrical issues (e.g. applying incorrect voltage to the coil) Dirty transmission fluid, which may cause the shift solenoid to become stuck open or closed.

Car begins to roll when the shift lever is in park had only starts in the neutral position, just rebuilt the transmission
ANSWER : The neutral start safety switch could be misaligned or a fault in the linkage and./or cable could be contributing to the problem because "Park" is not actually reached when you move the shifter. The whole mechanism from the manual lever on the transmission up to shifter will have to be inspected. The manual lever should be inspected separately inasmuch as you indicate abnormal resistance in certain gear selections. In addition, it sounds like the shift interlock may not be functioning. The recommended service to obtain a diagnosis of all of these issues is a shift linkage/interlock inspection. If you request that service, the responding certified mechanic will get this taken care of for you. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Transmission intermittently won’t shift to next gear
ANSWER : It is very possible that the transmission may require a full rebuild or a replacement in order for it to perform properly. Although you are able to shift into other gears, if certain gears are not working correctly, transmission damage may be the cause.

If the transmission has already been diagnosed by the dealer that it needs replacement and the transmission is still not shifting properly, it is unlikely that the transmission will get any better without replacement.

It does not hurt to attempt any reset procedure that may be available, but it is also unlikely that a reset of any kind will resolve transmission issues. Small things to check before replacing the transmission if possible would be the fluid level and any trouble codes that may have been stored due to the issue your transmission is causing.

If any codes exist, this may lead you to other possible parts inside the transmission that may be able to be replaced and have your transmission working again as it should. You can get a second opinion from an local expert, such as one from YourMechanic, in order to diagnose your shifting problem and advise you on the next steps.

Kia Optima 2004 v6 LX new engine old transmission no problems before with transmission now my transmission is shifting a high rpm
ANSWER : Hi There,
This may be an issue related to the communication of the PCM and the TCM (Transmission control module). As you may know, the TCM relies on the PCM to transmit information related to RPM’s, which the TCM then uses to determine when to direct the transmission to shift. The transmission control module has various sensors such as vehicle speed sensors, wheel speed sensors, throttle position sensors, turbine speed sensor, and transmission fluid temperature sensors that all direct information to it in order for it to perform it’s function. Other functions controlled by the TCM are components such as a kick down switch, traction control system, and cruise control module. Any of these may also affect the way the transmission control module performs and controls the transmission and the shifting of your vehicle. I would suggest having a professional from Your Mechanic come to your location to properly diagnose your transmission problem.

Transmission issues, rough shifting and noise
ANSWER : Many different faults can cause the vehicle to shift roughly. The most common would be low fluid level in the transmission, transmission mounts, the torque converter, or one of the shift solenoids. If you’d like to get this checked before moving forward with a repair, a qualified technician, such as one from YourMechanic, will be able to diagnose your shifting issue and perform any repairs required.

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.

Especially when cold, I notice shifts in low gears on my transmission
ANSWER : Hello. If servicing the fluid and filter did not help, then it may be possible that the transmission is worn. If any of the clutch packs that the transmission uses to shift wear out, they may slip and cause harsher shifting than normal. If the problem only occurs when the transmission is cold, then it may be possible that the clutch discs are worn, but can properly grip when the transmission and fluid reach operating temperature. I would recommend double checking the fluid for any signs of damage or wear, any unusual smells or color. If the fluid checks out. If you need help having this looked at, I would then move on to having the shifting issue diagnosed to see if the transmission may be faulty.

Transmission shift hard after high speed driving but shifts normal after engine is off for a while.
ANSWER : Hi there. Transmission fluid should be flushed every 50,000 miles to help avoid issues like you are experiencing. So, it’s probably a good idea to have your transmission fluid flushed and filter replaced, as the obstruction of debris or worn out fluid can cause the hard to shift issue you’re experiencing.
