What’s a Transmission Shift Solenoid and Why Does It Matter?
The role of a transmission shift solenoid is to control the flow of transmission fluid. The transmission control module (TCM) sends an electrical signal telling the shift solenoid when to transfer fluid into and out of the transmission and at what rate.
Your vehicle’s computer, specifically the transmission control unit, takes information from the engine, speed sensors, and other parts of your vehicle determining the best time to shift gears for power, fuel efficiency, and similar aspects of operation.
SIGNS OF A BAD TRANSMISSION SHIFT SOLENOID
Delay shifting upon acceleration and deceleration
Your transmission is stuck in neutral
Rough shifting
Engine revs loudly even when you apply the brakes
Your transmission can't downshift and the engine is loud
If you are concerned that recent loss of power in your vehicle may be related to issues with your shift solenoids or your transmission in general, it is vitally important to have the problem investigated quickly before more damage can take place.
