Gearshift won’t shift

The gearshift is not shifting.
Experienced mechanics share their insights in answering this question :
Hi. This is a common thing that owners of your particular vehicle encounter. Usually the cause of the problem is within the shift linkage. The shift linkage is built with plastic bushings that overtime become brittle and loose it connection to the transmission. I recommend that a technician inspect your transmission and determine if this is a shift linkage, gear selector, or another issue.

Common reasons for this to happen:

Transmission cables usually break due to stretching, which happens over time or can result due to speed shifting or jamming the car into gear. Stretched Transmission Cable: Prior to breaking, a transmission cable will stretch. When this happens the car may be hard to put in park.

It`s a type of car problem that`s not hard to notice. 2021 Chevrolet Trailblazer transmission problems can show up as shifting delays, grinding when accelerating, the car shaking at any speed, or whistling noises or a burning smell coming from beneath the hood.
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.
The standard Chevrolet Trailblazer has a 4.2-liter, inline six-cylinder transmission with four-speed automatic.
Worst Years for the Chevy Trailblazer Include 2002-2005 for Poor Reliability Scores and Low Price Spread Over Newer, More Reliable Alternatives.
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.
Continuously Variable Transmission (CVT)

You`ll find the CVT in the Trailblazer paired with engines powering the front wheels — both the 1.2L and 1.3L ECOTEC engines.

Blocked shifter

Most of the time, it is found that the shifter is clogged due to the entry of any foreign particles in it. This will also lead to the situation in which the Mercedes will not be able to shift into park or for that matter any other gears depending upon the location of the blockage.

Your manual transmission gears see a lot of use and over time, they will begin to wear down. The normal wear and tear can cause sticking of the gearshift as the gears fail to engage. This does tend to happen more often with the first two gears because they are the ones that are shifted to and from most often.
The most common reasons are: Shift lock solenoid – The shift lock solenoid is the mechanism that stops the BMW from being able to be shifted out of park when the vehicle is off, it also won`t let you put your vehicle into drive without turning on your ignition and putting your foot on the brake.

Won’t shift out of first unless you let go of gas but it will shift back down and never grab second
ANSWER : If you have all the drive shafts in the front and rear, then you will damage the transfer case or one of the axles if you drive the vehicle and engage the front end. The two different gear ratios will do this. As far as the transmission goes, you have a problem with the governor inside the transmission and may have bad second gear parts. Have a mechanic pressure test the transmission and diagnose the shifting issue for you.

My car won’t shift past 30mph while driving and it revs up.
ANSWER : Hi there. It looks like you’ve got multiple problems with your 95 Ford Taurus. The transmission issue may be due to a clogged hydraulic line, which is why most certified mechanics will recommend a transmission flush as opposed to just adding oil when there is a shifting issue. The issue with the battery is most likely due to the alternator or could be electrical due to a bad connection. The problem with many older cars is that sometimes age and parts fatigue will show up quickly, even with just 70,000 miles on the vehicle.

My suggestion to you is to contact a local ASE certified mechanic who can give your car a complete safety inspection to let you know what needs to be fixed before you spend any more money chasing problems.

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.

My windows won’t go down, my instruments don’t work, my car won’t go in park without shift release
ANSWER : Hi, thanks for writing in. In most cases, the problems you’re describing are caused by damage to the electrical system either at the fuse box or through relays that send electrical signals to each component that isn’t working; such as your power windows, instrument panel and others. If the vehicle was exposed to lots of water, this may have damaged the electrical system or the vehicle’s on board computer as well. The best way to reduce the stress, time and money on trying to find the exact source of your problems is to have one of our local mechanics inspect your Honda Accord for electrical problems at your home or office.

Won’t shift past 2nd gear . It drives normal to 2nd gear but wont shift into 3r – 2000 Ford F150 4×4
ANSWER : Hello – I don’t think this is related to switching back to 2WD per se. There is a shift position sensor on the side of the transmission, and it’s possible that the snow activity caused moisture and/or dirt to get into the sensor. I would recommend a transmission inspection by a mobile, professional mechanic, such as one from YourMechanic, who will come to your location, diagnose this problem, give you an accurate assessment of damage and cost estimate for repairs.

The truck won’t shift out of park so thinking that it’s the park shift interlock solenoid? Is that a good possibility that’s what
ANSWER : Hi there. First thing to check would be, whether the brake lights are functioning at the time it won’t shift out of park. There is a possibility, there is a poor connection at the fuse. It could be, a faulty brake light switch not supplying power to the shift interlock solenoid. There may be, a poor connection or wiring concern. It could be, a faulty shift interlock solenoid. I recommend having your vehicle’s shifting issue be diagnosed and repaired by a certified technician, such as one from YourMechanic.

My 98’Saturn won’t shift out of 2nd gear. Could it be a shift solenoid for 3rd & 4th?
ANSWER : Hi there. Are there any lights on; check engine, transmission, etc.? A code retrieval may be helpful if there are any codes stored. Codes/data could lead a qualified technician in the right direction of diagnosis as this could be a shift solenoid, a shift valve, valve body, or even a turbine speed sensor circuit fault. When transmission problems like this arise always check the basics first; fluid level and condition, engine and transmission mounts, battery condition, ground points, and warning lights. A faulty battery may look ok, but a failed cell or low state of health is all it takes to vary the supply of voltage to the solenoids and sensors and create a host of problems. I suggest having a qualified technician perform an inspection to avoid replacing unnecessary parts. Your Mechanic has several technicians available that can assist you with a car does not shift past second gear inspection.

Truck will shift sometimes then it doesn’t shift. If you wait a while it will shift again. We are trying to figure out what’s going on
ANSWER : Hi, thanks for writing in. The first thing I recommend is to make sure the ATF (automatic transmission fluid) is full.

Does the transmission shift up a gear or two and stay in that gear, or does it drive fine for a bit, then stop shifting until you turn the car off or sit still with the motor running? Or, do you continue to drive and eventually it begins shifting again. Are there any codes?

What I would do if I were diagnosing your truck would be to connect a scanner and study the data while driving to know what is going on. Without said data and not quite being clear about what is happening, it comes down to solenoids or sensors that the TCM (transmission control module) uses to calculated shift points based on load values determined by the PCM (powertrain control module).

I’m afraid all I can offer you at this point is suggesting you make sure the fluid is full and clean. If it isn’t clean, begin by replacing the filter in the pan and do a transmission fluid exchange, not just pan drop with a drain and fill. This doesn’t get all the ATF out of the transmission, and when there are problems, it pays to be as thorough as possible.

I recommend the following inspection if you should need further assistance: Car hard to shift

Hope this helps and best of luck!
