What might my shifter issue be?

The car states and sounds fine. It went go into any gear though… The clutch has been replaced but I don't think the slave cylinder was. Could it be this? It started out with just popping out of gear but now won't go into any gear.
My car has a manual transmission.
Experienced mechanics share their insights in answering this question :
Hi there. The popping out of gear could be a shifter alignment issue and/or an internal transmission concern (ie; synchronizer, hub, or input to output shaft bearing). The won’t go into any gear could be a faulty clutch slave cylinder and/or faulty clutch master cylinder. Proper diagnoses is important. I recommend having your vehicle’s clutch is not working be diagnosed and repaired by a certified technician, such as one from YourMechanic.

How to Identify and Fix Common car Problems ?

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.
In most cases, this issue is caused by a damaged shift solenoid or perhaps an obstruction of debris inside the transmission hydraulic lines. It could also be caused by damaged inside the transmission…
When a shifter becomes hard to move, it is usually the interlock cable. AKA, shift cable. This cable slides in a housing and connects directly to the transmission. When this cables becomes worn, it gets hard to move inside the housing.
Mitsubishi Lancer transmission problems can present themselves as shifting delays, jumping or grinding during acceleration, the car shaking on the road, or a burning smell or whistling sounds coming from under the hood.
Common signs include the indicator not matching the gear and the vehicle not turning off, starting in another gear, or not going into gear at all.
The Vehicle Speed Sensor measures vehicle speed. When it fails the transmission can stop shifting or shift late and harsh. A bad VSS may also inhibit overdrive and the converter clutch.
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.
You can also force your automatic transmission to downshift into a lower gear. Here`s how to do it: As you approach a situation where you`d like to downshift, ease off the gas pedal. Allow the transmission to shift to a lower gear.

Hello. I have a question about my 1999 Olds Bravada (AWD). I am having issues with my shifter. To start with, my shifter will n
ANSWER : This will have to be evaluated first hand by a trained professional especially as more than one issue could be occurring here. If you request a shift mechanism/manual lever/cable inspection, the responding certified mechanic will identify the underlying fault and let you know what has to be done to get this resolved once and for all. To address this briefly, though, if you are not able to start the car in park, that could be due to a faulty or poorly adjusted neutral start safety switch. If you can shift from park to any gear without putting your foot on the brake, then there is something wrong with the interlock mechanism. The failure in Park (vehicle moving) could be a problem with the manual lever (on transmission), the cable, or there could be a problem with the park rod mechanism within the transmission. The only way to get this resolved is to have it inspected and diagnosed by a professional and if you request the above inspection YourMechanic will get this fixed. If you have further questions or concerns, do not hesitate to re-contact YourMechanic as we are always here to help you.

Car jerks when accelerating in reverse & makes grinding noise. Is this a transmission or computer issue?
ANSWER : Hi there. Typically when you hear a grinding noise when you move forward or in reverse it’s usually an indication of a gear fault either in the transmission or another driveline component. If this occurs only when in reverse, it’s likely a damaged reverse gear. It is also possible that it’s a hydraulic fluid issue not supplying enough lubrication or pressure inside the lines to fully open the gear. I would recommend having a professional mechanic come to your location and complete a car is hard to shift inspection, so they can diagnose the source of your issue and recommend repairs that should resolve this problem.

What is wrong with my car?
ANSWER : If the vehicle is not starting, simply request a no start diagnostic and the responding certified mechanic will get the underlying fault identified and resolved. Basically, the first thing to do is load test the battery. Although I understand your suspicion that the immobilizer may be preventing the car from starting, until an actual diagnostic is performed that is a speculative cause. If the immobilizer system is on, you may see a security warning light. If you see such a light, to temporarily override the immobilizer system, see these instructions. If you do not see a warning light, again I would not assume that the immobilizer is the problem because there are lots of other potential causes for the no start you are describing.

With a fully charged battery and the immobilizer system off, if the starter motor does not operate, either there is no power to the starter motor, hence the starter circuit would have to be diagnosed, or the starter itself is bad and it would be replaced. If there is no starter motor operation at all, that is if there is no starter operation with the key held in the "start" position, the procedure is to test for power and voltage drops to the starter motor/solenoid. If there is no power or a large voltage drop is measured, then the electrical circuit supplying the motor has a fault. That circuit begins at the battery and includes grounds, wiring (some of which is very heavy cabling), fuses, relays, the ignition switch, neutral start switch, and terminations. Basically, with a fully charged battery, and with the key held in the "start" position, the starter is either getting power or it isn’t. With the key in the "start" position, if the starter motor is getting power but the starter doesn’t work, then the starter is condemned and replaced. Note that starters can and sometimes do develop intermittent faults due to bad spots on the armature. The bottom line is if there is battery voltage to the starter (and no excessive voltage drop) and yet the starter doesn’t work, it’s dead. If you desire that a certified mechanic resolve this, please request a no start diagnostic and the responding certified mechanic will get the problem diagnosed and repaired for you.

Need help finding the name of the plastic ring that holds the shifter in place
ANSWER : Hi there. The part that you are looking to replace is called a shifter seal and there is also a shifter spacer. The spacer is the plastic ring that hold the shifter in place. The metal shifter seal is the thin wavy seal that goes on the top of the shifter. If you need further assistance with your vehicle, then seek out a professional, such as one from YourMechanic, to help you with your shifter to have this addressed.

I have an automatic shifter that suddenly got loose. I no longer need to push in the button to shift from park to drive.
ANSWER : It sounds as though you have probably had a shifter cable break, or a corresponding part of the shift linkage. Of course, it may have been the shifter has failed, but it is more than likely the shift cable, as this is the most common failure. It would be necessary to do a visual check of the cable where it mounts to the transmission. It would be best to have someone move the shifter through the gears while you watch to see if the linkage is moving. If this is something that you feel you could use a hand in diagnosing and/or repairing, contact a certified mechanic, like the mobile mechanics available at YourMechanic.com.

What other issues are there if you have a locked shifter?
ANSWER : Check the shifter interlock solenoid and see if it has failed or lost power. The shifter interlock solenoid keeps the transmission in park without moving the shifter automatically and also prevents the shifter from going into park when the vehicle is in motion.

If you need further assistance with your transmission not shifting into drive, then seek out a professional, such as one from Your Mechanic, to help you.

My transmission is stuck on reverse but my shifter is on park. Can’t move shifter at all.
ANSWER : Hi, thanks for your question. I’d be happy to offer my insight. I suggest checking the transmission shift cable connection at the transmission to see if the cable came loose from a defective cable end bushing.
