How does a valve body select a gear?
By channeling hydraulic fluid through a series of paths, the valve body is able to trigger the correct clutch pack for the selected gearing. Inside of the valve body, there are a number of valves, each of which is referred to by the shift that it’s responsible for.
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.
Which is the most important part of the valve body?
Each of the many valves has a particular role in the valve body and has a name for that feature. The most important part of the valve body is the manual valve. Connected to the gear stick handle, it instructs the right passage for hydraulic fluid to pass through.
What is the body of a transmission valve?
Not to be confused with the intake and exhaust valves in your engine, the valve body is an assembly inside an automatic or CVT transmission that routes automatic transmission fluid (ATF) throughout the transmission.

When do you know you have a bad transmission valve?
If the answer is yes to any or all of these scenarios, then chances are you have a bad transmission valve body. If you try to change gears with the shifting stick and you notice it slips regularly, then you likely have a problem with the transmission valve body.
How can I identify the model number of my shower valve?
To identify the model number of your shower valve, first remove the trim, or handle and decorative plate. This allows you to expose the valve for proper identification. For assistance with removing the trim, refer to “Identify and Remove Single-Control Bath and Shower Trim”.
How much does it cost to replace transmission valve body?
The cost of replacing a bad transmission valve body will depend on the make and model of your vehicle. However, it is one of the more expensive car part replacements that you will need to make. On average, a transmission valve body piece will cost you anywhere from $200 to $500. Then you must consider the labor costs which will be quite extensive.

Which is the valve responsible for the upshift?
Inside of the valve body, there are a number of valves, each of which is referred to by the shift that it’s responsible for. For example, the third-fourth valve activates the upshift from third to fourth gear, and the fourth-third determines when to downshift from the fourth to the third gear.
Which is an example of a bad transmission valve body?
Some examples of these functions are gear selection, torque converter lockup, and even lending assistance to the ABS system in certain scenarios. When you experience a symptom of a bad transmission valve body, it is typically very noticeable.
When do you need a new transmission valve body?
If one of these solenoids were to fail, you may find yourself locked out of certain gears, or you may be unable to shift at all. A qualified transmission shop may be able to replace a single component inside the valve body, or you may need a new valve body depending on what the root cause of the problem is.
