What is the Governor RPM in Automatic Transmission in Cars?
The governor RPM in an automatic transmission is the maximum speed at which the transmission will allow the engine to turn. This is a safety feature that helps to prevent the engine from over-revving and damaging itself.
The governor RPM is typically set at a few hundred RPM below the engine’s maximum RPM. This gives the engine some room to rev up when accelerating, but prevents it from reaching its maximum RPM, which could cause damage.
The governor RPM can be adjusted by a qualified mechanic. However, it is important to note that increasing the governor RPM can increase the risk of engine damage. It is therefore important to only adjust the governor RPM if you are confident that you know what you are doing.
How does the governor RPM work?
The governor RPM is controlled by a centrifugal governor. This governor is located inside the transmission and consists of two weights that are attached to a spring. As the transmission speed increases, the weights move outward, which causes the spring to stretch. This stretching of the spring causes the governor to open a valve that allows more transmission fluid to flow into the transmission. This increased flow of transmission fluid causes the transmission to shift to a higher gear, which reduces the engine speed.
What are the symptoms of a governor RPM problem?
The following are some of the symptoms of a governor RPM problem:
- The engine over-revs
- The transmission shifts erratically
- The transmission does not shift into overdrive
How to fix a governor RPM problem
If you are experiencing any of the symptoms of a governor RPM problem, it is important to have your transmission inspected by a qualified mechanic. The mechanic will be able to diagnose the problem and make the necessary repairs.
Conclusion
The governor RPM is an important safety feature that helps to protect your engine from over-revving. If you are experiencing any problems with your transmission, it is important to have it inspected by a qualified mechanic.
