This kind of reaction is often a sign of low transmission fluid or a faulty transmission control solenoid. As you know, 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. This type of problem is amplified any time the transmission is low on fluid creating a drop in hydraulic pressure. I would recommend having a professional from YourMechanic come to your location to diagnose and inspect your vehicle.

The throttle cables need checking. As we have mentioned earlier that changing the transmission fluid alone solves many transmission-related issues. But, if you change this transmission fluid and your auto transmission still won`t shift into the third gear, the throttle cables are the next suspect.
If the automatic transaxle warning indication/light illuminates, the transaxle has an electrical problem. Continuing to drive your Mazda in this condition could cause damage to your transaxle. Consult an expert repairer, we recommend an Authorised Mazda Repairer as soon as possible.
If the torque converter is broken, or if there is a low fluid level in the transmission, the converter will not do its job, and the car will be unable to maintain power at low speeds, which causes the engine to shut off.
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.
Abnormal shifting: If you are experiencing problems with the way that your car is shifting gears, this could indicate a serious problem with your transaxle. This can manifest itself in a variety of ways, including hard shifting, slipping gears or failure to shift.
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.
Most commonly when the car stalls while driving, but starts right up after, the cause is an intermittently failing crankshaft position sensor or camshaft position sensor. The first step to diagnosing this problem however, would be to scan the engine control module to check for fault codes.
There are a large number of reasons why your car might stall while driving. It could be a dead alternator, a bad coolant sensor or lack of fuel, just to name a few. Is your car stalling while accelerating? If so, then it could be a major vacuum leak, clogged fuel filter or a bad fuel pump.
The most common reason your car starts then dies immediately is because of a lack of fuel in the engine. This often happens because there is a small amount of fuel in the fuel rail, which helps to start the engine.
Grinding noises, transmission leaks, burning smells, noisy idling, and shifting delays are all common symptoms of a clogged filter.
Maintain Proper Transmission Fluid Levels
The #1 cause of transmission failure is low fluid, which causes overheating. In automatic transmissions, it causes delayed engagement, harsh shifts, and slippage.
A healthy transmission shifts smoothly, and often you won`t even notice the change of gear. However, if your car shakes during gear shifts, something is wrong with your transmission.
Typically, when your transmission begins to fail you may start to notice some form of difficulty when changing gears. Occasionally you may hear or feel a clunk noise when you shift gear. Another sign of a rough shifting is difficulty in accelerating to the speed for the gear that it is in.
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.
Drivers with transmission issues in their vehicles can experience bucking, surging, jerking, and stuttering in while changing gears or pressing the gas pedal. This may feel like a clunk or thud and your vehicle may also struggle to accelerate. Automatic transmission fluid is critical to your car`s shifting.
With the vehicle off, turn the key to the “on” position, but don`t start the car. Hold the TPMS reset button until the tire pressure light blinks three times, then release it. Start the car and wait 20 minutes for the sensor to refresh.
The TCM fuse is in the main fuse block and is probably 10 amps. If the fuse is blown, that is confirmation but the faulty fuse means there is a short circuit in the TCM and/or wiring that would have to be traced and repaired.
The transmission position sensor is usually screwed onto the side of your car`s transmission. As you move the automatic gear selector from park/neutral to drive or reverse, it detects the changes. It then enables and disables the connection to the starter motor circuit, affecting your car`s ability to start.
Shift solenoid B allows the transmission to shift between 2nd and 3rd gear. When the powertrain control module (PCM) records code P0758, it indicates that the PCM is unable to detect the proper change in engine speed or increase in ground speed that should occur during a 2nd to 3rd gear shift.
Faulty spark plugs can cause the car to exhibit starting troubles. Worn out plugs does not produce sufficient sparks, which is needed for starting the engine. This results in the engine to stall and fail to start quickly.
