Symptoms of a Bad Transmission Governor Th350

The transmission governor in TH350 automatic transmissions plays a crucial role in regulating the shift points and controlling the transmission fluid pressure. When the governor malfunctions or becomes faulty, it can result in various issues with your vehicle’s transmission system. In this blog post, we will explore the symptoms of a bad transmission governor TH350 to help you identify potential problems and take appropriate action.

Th350 Bad Transmission Governor Symptoms

1. Delayed or Erratic Shifting

One of the primary signs of a faulty transmission governor is delayed or erratic shifting. You may notice a delay in the transmission engaging when you shift from Park to Drive or experience jerky and inconsistent shifts while driving. This symptom indicates that the governor is not sending the correct signals to the transmission to initiate smooth gear changes.

2. High RPM at Highway Speeds:

If your vehicle’s engine seems to rev excessively at highway speeds without a corresponding increase in acceleration, it could be due to a malfunctioning governor. A faulty governor may fail to regulate the transmission fluid pressure, causing the transmission to stay in lower gears for longer periods, leading to increased engine RPM.

3. Slipping Gears:

A transmission governor that is not functioning correctly can also cause gear slippage. Slipping gears occur when the transmission momentarily disengages from its current gear without shifting to the next one properly. This symptom may manifest as a loss of power, surging or a whining noise from the transmission.

4. Failure to Upshift:

When the transmission governor is malfunctioning, your vehicle may experience difficulties shifting to higher gears. This can lead to the transmission staying in lower gears, even at higher speeds, resulting in reduced fuel efficiency and potential engine strain. If you notice that your vehicle’s RPM continues to increase, but there’s no corresponding shift to a higher gear, it may be a sign of a faulty governor.

5. Harsh or Delayed Engagement:

A bad transmission governor can cause the transmission to engage abruptly or with a delay when shifting into gear. This symptom can result in a noticeable jolt or a harsh engagement, making your driving experience uncomfortable and potentially damaging the transmission components over time.
