What happens when a transmission valve goes bad?
A valve body issue may even trigger limp mode or leave you stranded. Below are some of the common symptoms you may experience if you have a bad transmission valve body. There are many solenoids that the TCM can turn on and off to direct the flow of transmission fluid inside the valve body.
How does the transmission valve body work in a car?
Your vehicle’s transmission valve body works by welcoming transmission fluid into it and moving it around based on what gear you need your transmission to be in. Your transmission valve body will move the fluid through its various channels quickly to activate the right bands in your transmission while you’re driving your car around.
Can a transmission valve be replaced at home?
There are many tiny components inside a transmission valve body that must function exactly as designed for proper transmission operation. If you take your vehicle to a qualified transmission repair shop, there is a chance that the shop may be able to replace an individual component instead of the entire valve body.
How do you remove a solenoid valve from a transmission?
Use a wrench and a screwdriver to remove all bolts and screws that are holding the block-like assembly in place. Carefully pull the solenoid valve body off the underside of the transmission and place it on a flat work surface.

How often do transmission valve bodies break down?
In spite of the fact that transmission valve bodies are very important components in your transmission, they don’t break down on car owners very often. In fact, it’s not uncommon at all for a transmission valve body to last for as long as a car does.
Can a shifting stick slip in a transmission?
You should never have a shifting stick which slips if your transmission valve body is fully functional. If the transmission is not able to downshift, then hydraulic fluid must not be entering the transmission valve body properly. Once this happens, the gears cannot be pressurized properly which degrades the performance of the vehicle.

What is the best way to clean a transmission valve body?
If a valvebody has sticking valves or clogged passages you have to find the source of the debris that caused it and fix that (means overhaul of the transmission) Cleaning a valvebody alone is a waste of time and should only be attempted by a trained transmission tech as part of a transmission overhaul. Ummm. Why are you asking?
What happens if you dont have a valve body?
Without fluid, the valve body can’t work, and if you can’t shift, it’s going to be very hard to drive to the store to get more. Valve bodies are the central control of automatic transmissions, and as long as they’re working correctly they’re miraculous.
What does it mean when your car motor does not crank?
