Yes
The computer that controls the transmission relies on these to decide when to shift.
There are sensors inside the trans, outside the trans, and on the engine that will all affect shifting.
No, the alarm will not affect the trans.
A "speed" sensor can affect the shifting of the trans.A "speed" sensor can affect the shifting of the trans.
Yes.
Bad spark plug wires affect many areas of your vehicle. However, gear shifting in an automatic transmission is not one of them.
Yes, vacuum can affect transmission shifting, particularly in automatic transmissions that use a vacuum modulator. The modulator adjusts the transmission's shifting points based on engine load and speed, relying on vacuum pressure to function properly. If there is a vacuum leak or insufficient vacuum, it can lead to delayed or erratic shifting. Therefore, maintaining proper vacuum levels is essential for smooth transmission operation.
If you mean low oil or fluid in the transmission, then YES, it will lead to shifting problems. Low engine oil will not affect shifting.
A vehicle may jerk in second gear with an automatic transmission due to several factors, such as low transmission fluid, which can lead to inadequate hydraulic pressure, or worn-out transmission components that affect shifting. Faulty sensors or software issues in the transmission control module can also cause irregular shifting behavior. Additionally, issues with the torque converter or engine misfires can contribute to the jerking sensation. It's advisable to have the transmission inspected by a professional to diagnose and resolve the issue.
Yes, it is possible on an electronically controlled transmission.
Yes, common problem to have a high resistance switch.
Code PO731 refers to an issue with the transmission, specifically indicating that the "Gear Ratio Incorrect" is detected in first gear. To fix this, start by checking the transmission fluid level and quality, as low or dirty fluid can affect shifting. Then, inspect the transmission components, including the input and output sensors, for faults or damage. If necessary, perform a transmission recalibration or consult a professional mechanic for further diagnosis and repairs.
Yes, a faulty speed sensor can affect the transmission function in a 1991 Dodge Shadow. The speed sensor provides critical data to the transmission control module, which helps regulate shifting and performance. If the sensor is malfunctioning, it can lead to erratic shifting, poor performance, or even transmission failure. Therefore, addressing any issues with the speed sensor is important for maintaining proper transmission operation.
