What are the codes for the shift solenoids?
Most automatic transmissions incorporate a number of shift solenoids, depending on the number of gears inside. The trouble codes related to this, the “E” solenoid, are codes P0770, P0771, P0772, P0773 and P0774 based on the specific malfunction that alerts the PCM to set the code and illuminate the Check Engine Light.
What causes a transmission code of p0770?
Causes for this P0770 transmission code may include: Insufficient fluid level. Dirty or contaminated fluid. Dirty or clogged transmission filter. Defective transmission valve body.
What is the Shift Solenoid code on a Toyota 4Runner?
I have a 2000 Toyota 4Runner 4X4 V6 Auto Trans with 110,000 miles. On long extended trips or running errons during the day my check engine light comes on with a P0770 code (Shift E Solenoid Malfunction). Also known as the SL solenoid.
What does a solenoid do in a transmission?
The transmission solenoids are responsible for opening or closing valves in the valve body to allow transmission fluid to flow to the clutches and bands to shift the transmission smoothly as the engine accelerates.
What are the symptoms of a transmission solenoid problem?
The most common symptom of a damaged transmission shift control or wirings is a warning light on your dashboard. This is often a check engine light or a transmission warning light. If you see a warning light on your dashboard, read the trouble codes with an OBD2 scanner and start your troubleshooting there. How to Diagnose a Shift Solenoid Problem?
What happens when Shift Solenoid goes bad in 4L60E?
Inconsistent Shifting– Often when a shift solenoid goes bad in the 4L60E, it’ll cause a lot of erratic shift behavior. The transmission will skip gears. It also may act like it is trying to “find the right gear”.
How does the solenoid work in a car?
As you drive, the car’s computer determines which gear is optimal for your speed. The transmission control module (TCM) — the brains of the transmission — will send power to one of the shift solenoids in order to shift gears. Inside the solenoid, there’s a plunger surrounded by a magnetic coil.
