Automatic slips into neutral
My car has an automatic transmission, which lately started slipping into neutral during driving. This happens when the engine is still cold, whereas it has no issues when it warms up. How serious is the problem?
Experienced mechanics share their insights in answering this question :
Hello. This transmission issue is a serious problem, because eventually the transmission will stop working. The transmission could stop working in the next couple of months or longer. It is possible that there is a problem with the valve body or solenoids in your transmission. It seems like either or both of these components are sticking when the transmission is cold. Letting the truck warm up for an extended period of time will help this issue and may prolong the replacement of the transmission. I suggest having the vehicle inspected by a qualified technician, such as one from YourMechanic, they will be able diagnose your slipping gear and suggest a fix from there.

In an automatic transmission, slipping can be caused by wear and tear on numerous different parts. These include damaged or worn clutch plates, transmission bands, and solenoid packs. If your automatic transmission has been slipping, it`s likely a technician will replace some or all of these parts to fix the problem.
If your transmission unexpected pops into neutral or sometimes slips in and out of gear while you`re driving, you may have a serious risk of getting into an accident. Imagine this happening at the exact moment you accelerate to pass another car. The engine revs, but no power is being delivered to the wheels.
Low fluid levels
This is usually the main reason why gears start to slip. It is important to check fluid levels regularly and ensure they do not fall below the minimum. If the levels are low, there is usually not enough hydraulic pressure to engage the gears.
While in neutral, the gas pedal does nothing to speed the vehicle; no power from the pedal is transmitted to the wheels. Neutral is rarely engaged in most driving trips, leaving some automatic drivers wondering – when should you shift into neutral?
The Transmission Range Sensor tells the PCM the position of the transmission shifter. 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.
If you have a neutral dropout, check your transmission fluid, transmission bands, worn-out gears, and solenoids (electrical valves that control transmission fluid).
1. At the top of all auto repair experts lists for causes of problematic transmissions is low transmission fluid. Usually caused by a leak somewhere in the system, low or contaminated fluid makes it nearly impossible for the transmission to automatically shift gears and run smoothly.
This means that it is not shifting smoothly from gear to gear or that it is not staying fully in gear as you drive. This can be the sign of internal damage or it may just mean you are due for a standard transmission service to replace the transmission fluid, filter and pan gasket.
A condition that feels similar to slipping, Neutral drop-out is where the transmission drops into Neutral when the vehicle comes to a stop or while driving, typically at slower speeds.
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.
a problem with one or more of the solenoids can cause a lack of pressure, resulting in hard, soft or delayed shifts. a failed shift solenoid can also cause transmission slippage, where your engine revs faster but the car stays at the same speed.
The switch prevents the engine from starting when not in park or neutral. This eleiminates the risk of starting an automatic car in drive or reverse mode. Located in the linkage or the transmission box, a bad neutral safety switch can cause irreversible damage to your car`s engine and transmission.
You might expect that the first step in fixing a slipping transmission is changing or flushing the fluid, but that`s not always the case. A fluid and filter refresh can help in some cases, but not always—read on. If the transmission is slipping, it likely means it already has worn internal components.
The neutral safety switch for an automatic transmission is located inside the transmission case or in the linkage that allows the vehicle to shift gears. This switch prevents you from starting the engine when the transmission is in any gear other than Park or Neutral.
Transmission bands can wear out and cause slipping.
Bands are what link the gears in the automatic transmission together. To fix this problem, the defective bands should be replaced. Sometimes the bands are fine and only need adjustment. The clutch plates might also need to be replaced or adjusted.
A neutral drop burnout can be harmful to a car, as it puts a lot of stress on the transmission and driveline components. Extremely harmful.
To test the torque converter, you must step on the pedal to the floor and accelerate your engine for up to five seconds. The reading for the revolutions per minute (RPM) will max out at the stall speed.

Avoid Using the Neutral Gear while sliding the vehicle down a slope. This action will not speed up the car instead it will actually slow it down and not only that but the transmission cuts fuel to the engine that it doesn`t get the proper lubrication to run smoothly. This can significantly damage the car.

I put my 05 nissan altima in neutral to push it because it won’t crank now it will not go past neutral to go in park.
ANSWER : Have you tried depressing the brake pedal while the key is set to run to see if the lock will release? You may have a park/neutral locking solenoid starting to fail. The cranking and no start problem could be something like a failed camshaft or crankshaft position sensor. Consider hiring an experienced technician like one from YourMechanic who can come out and take a closer look at the stuck shifter and no start concerns in order to offer a more personal diagnosis.

Transmission slips when cold but shifts perfect when at operating temperature.
ANSWER : Your transmission may have defective pressure and control solenoids or could have bad seals inside the transmission. Either way you will need to have a qualified transmission mechanic run a diagnostic check to see if you are having internal leakage from leaking seals. The seals are the most common problem and would require a transmission overhaul to fix. I recommend having a certified mechanic, like one from YourMechanic, diagnose why your vehicle is intermittently hard to shift.

My car will only start in neutral and not park. Will it continue to start in neutral. 2003 Suzuki Aero
ANSWER : Hello. It sounds like your transmission position sensor is failing. This sensor sends a signal to the computer to let it know what gear the vehicle is put in and allows the vehicle to start in park and neutral. It sounds like the park part has failed. It should continue to start in neutral as long as it does not fail completely. If you want to have this taken care of, consider YourMechanic, as a certified mechanic can come to you to [diagnose why it will not start in park] https://www.yourmechanic.com/services/car-is-hard-to-start-inspection

My slip indicator light is on all the time. I just had the car serviced and tires rotated. Why would the slip indicator stay on?
ANSWER : Hi there. The Slip indicator light should blink at certain times. If the vehicle stability control system is operating (actively assisting with handling), you’ll see the Slip indicator light blink. This should also be taken as a warning that the road is slick, and you should drive with caution. If the light is always on, it could be caused by a sensor that is damaged, or may have an electrical connection that is faulty. It’s probably good to have a professional mobile mechanic come to your location and complete a warning light is on inspection.

My car always stuck in neutral I’m trying to put into drive still showing neutral, putting in R still showing N 2015 Fiat 500
ANSWER : Hi there – your Fiat "automatic" transmission is actually a 6-speed, dual-clutch manual transmission, with some rather sophisticated electronics and actuators attached to it. These boxes are notoriously complicated, with incredible complexity in the transmission controllers themselves. Your controller is having a problem deciding what gear it’s really in, and not selecting anything (as you have experienced). There are actually 2 Fiat Recalls (#16V302000 and 15V291000) on the gearbox. I would take your car back to your servicing dealer, and have them resolve this. They have the tooling and software update capabilities to resolve these kinds of issues. Good luck!

Gear shift slips over to Manual Transmission without touching. I have to hold it to keep it in Automatic.
ANSWER : Hi there. All automatic transmissions require transmission fluid for them to work. In your engine compartment by the right side next to the radiator area, there is a box in front of the air filter housing. Remove that box and below the air filter housing you will see the dipstick to the transmission. For the transmission not staying in automatic mode and conveying over to the manual mode only, the shifter has either broke inside or the circuitry has a short in the shifter housing. I recommend replacing the shifter assembly with a new one. If you need further assistance with your shifter not selecting automatic mode, then seek out a professional, such as one from Your Mechanic, to help you.

clunk when change gears and car goes in reverse when in neutral and wil not roll in drive
ANSWER : What you are describing may be due to a shift linkage adjustment issue and so the linkage should be inspected. The noise could be within or without the transmission and such will depend on an inspection. If outside the transmission, the clunk noise could be due to worn CV joints. If within, it could be due to too much endplay and/or bearing damage that has allowed end play. Certain hydraulic faults might also account for abrupt engagement. I recommend you request a shift diagnostic and the responding certified mechanic will identify the fault.
