How does the transmission vacuum modulator valve work?
by Greg Day. The transmission vacuum modulator valve determines how much load is on the engine so the transmission can shift properly. It has a vacuum line that connects to the intake and measures the amount of vacuum in the engine.
Can a bad vacuum modulator cause shift problems?
If you’re experiencing all of the above symptoms while having shifting problems too, then you likely have a faulty transmission vacuum modulator. As you just learned, the vacuum modulator is what allows the transmission to shift properly. Having a bad vacuum modulator will obviously affect normal shifting.
Where is the Transmission Control Module located on a car?
That way, the driving performance and fuel economy will be at the optimal level. The transmission control module can often be found below the cover at the back of the transmission case. It should be just below the engine control module’s position.
Is the vacuum modulator the same as the engine?
The vacuum modulator has a vacuum line which is attached to the intake valve and calculates the engine’s vacuum amount. Either way, both technologies have the same function. When we talk about the load on the engine, we are referring to how hard it must work just to maintain its functionality.

Where is the Transmission Control Module on a car?
The transfer of power from the engine to the wheels. The transmission performs the main role in transferring that power and the module is the component that controls the transmission. You will find this little component on the rear side of the engine.
