Honda, Linear Solenoid Symptoms
For Honda VETC Solenoid, what's that butterfly effect connection in between speed sensor, transmission solenoid, valve body, ECU and the gears?
Put it simple way, Speed sensors are analyzes by car's computer and then Transmission Control Unit sends instruction to shift solenoids.
With signals come from TCU, solenoids can execute the appropriate downshift or upshift.
The plunger, spring-loaded and wrapped with wire, inside the solenoid, will allow transmission fluid to flow into valve body when it receives the electrical charge from TCU or ECU.
The valve body then pressurizes the desired clutches, transmission gears are shifted accordingly.
COST OF TRANSMISSION SOLENOID REPLACEMENT COST
So now You know solenoid places a crucial middle role to execute whole process.
Now comes with some replacement cost of these spool valve solenoid, the VETC solenoid, called by Honda.
Different type of shift solenoids have different parts cost, labor cost and installation time.
Cost also varies on the Make and the Models of Your vehicles.
Some solenoids can be replaced individually so part cost may be lower, if they have aftermarket auto parts source.
If consider of complexity of transmission construction, the time and cost also vary.
The list above gives draft idea about maximum cost you may need to pay.
Best way is still to contact auto shop experts you trust for professional consulting.
HOW DO I KNOW MY TRANSMISSION SHIFT SOLENOID HAS FAILURE
There are 4 common warning signs of a bad transmission solenoid.
#1 You can't downshift.
Especially the gear is stuck in 2nd stage.
Even you apply brakes, you still can fell the engine continues to rev.
#2 Transmission got stuck in neutral mode
#3 Limp Home Mode
Accelerating function fails and you can't shift the gears.
This is the most often seen symptom when your transmission goes wrong.
#4 Erratic shifting or gear shifting is delayed.
Server shifting response delay and you will feel shifting is choppy and rough now.
Shift solenoid plungers, constantly bath in transmission fluid, controls the fluid flows through the valve body according to various circuits from TCU.
With using time, the metal debris caused by friction will be collected on the plungers.
Plungers may fail to work properly due to bores are stuck with these debris.
So get down to the nitty-gritty, regularly change the oil and make sure the transmission fluid clean is cruical to longer solenoid lifetime.
Or, you can also consider of cleaning the valve body which also may lead transmission malfunction, especially when you see the Error Code P2646
