Purpose of a Transmission Modulator
The purpose of a transmission modulator is to decide when a transmission shift should occur. It also informs the transmission of the type of load being placed on it. Pressure is regulated by the transmission modulator as well, allowing the transmission to function smoothly.
Problems
There are several problems that can occur with a transmission modulator, most of which happen naturally over a period of time. The modulators diaphragm is subject to rupturing, and leaks are known to occur as well. These types of problems in a modulator cause driving issues and may even cause the transmission to fail altogether.
Inspect
Often the first thing youll want to inspect is the line leading to the transmission modulator. If transmission fluid is visible once you disconnect the line, this indicates a leaking diaphragm. The modulator can also be checked for leaks directly using a handheld vacuum pump.
Remove
A transmission modulator can be removed from the transmission so it can be replaced. Before pulling the modulator from its housing unit, the retaining bolt and clamp will have to be untightened first. Because the actuating pin could fall when the modulator is being pulled out, special care should be taken to avoid losing it.
