If you notice that your car is taking longer to shift into gears, it could be a failing solenoid. Luckily, a bad shift solenoid is normally not an emergency transmission repair and you could continue driving the car for a while, although you will notice certain symptoms while driving.
What are the Symptoms of a Bad Shift Solenoid? In the worst-case scenario, if the shift solenoid has completely failed, it is possible that the transmission will not work at all and remain stuck in neutral regardless of what gear you put it in. It could also mean that the transmission skips gears because it just can’t find the right one. Sometimes there is a long delay in shifting and engagement which is often attributed to a bad shift solenoid. The 4L60E transmission will often fail to downshift if one or more of the shift solenoids are stuck because transmission fluid cannot be rerouted to the transmission to move gears.
In the 4L60E, shift solenoids can cause a lot of trouble. If the 4L60E shift solenoid is bad, your vehicle could experience failure to downshift, delay in shifting gears, inconsistent shifting, or being stuck in neutral. How do I Know if my Shift Solenoid has Gone Bad? Depending on the car’s design, a shift solenoid can be used to control a single gear or multiple gears. The car’s computer controls the shift solenoids in several ways including opening or closing the hydraulic circuit or controlling the plunger turning the circuit on and off. This all happens when the transmission changes gears and you continue down the road. When the wire receives an electrical charge from the engine control unit, the plunger opens and allows transmission fluid to flow into the correct areas. These solenoids have a spring-loaded plunger wrapped with wire. Based on this information, the engine control unit appropriately shifts using one of several shift solenoids. When you are driving, the car’s computer analyzes all sorts of data. The shift solenoid is a vital component to ensure you have a safe and reliable vehicle. When a little glitch in the system occurs for the vehicle transmission system, the whole thing often shuts down, leading to a frustrating situation involving a stalled car, a tow truck, and (often expensive) repair bills. If one of the solenoids fails, all sorts of transmission problems can occur. The E part of 4L60E means electronic this transmission has electronic control. The shift solenoids within the 4L60E transmission receive instructions from the engine control unit to open and close. Modern automatic transmissions use pressurized fluid to change gears each time a gear changes, the car’s computer activates a shift solenoid which directs the fluid so that the car engages in the correct gear. The 2021 cost estimates are given to repair the solenoids however these costs vary depending on the garage, location, and availability of parts. This blog outlines what a shift solenoid is, what it does, and its common symptoms when broken. Depending on the severity, it could mean the car is stuck in neutral becoming completely undrivable.
Solenoids can wear or break over time and need to be replaced. Regardless of its overall impressive reliability, the 4L60E will not function any better than its solenoids.
