Can a CVT valve be replaced without replacing the body?
Replacing the valve body without fixing the underlying cause of bad fluid may result in reoccurring the same transmission issues. When removing the output speed sensor and input speed sensor from the CVT, please pay attention to the padding/shims. Loss or damage to the padding or shims may cause damage to the transmission.
Why is my CVT leaking at the gaskets?
Like any transmission, CVTs are susceptible to leaks at the seals and gaskets due to lack of use, overuse, overheating and even normal wear and tear. Spotting a leaking CVT can be more difficult than finding a leak in a traditional automatic transmission because the fluid is usually not a bright red color to distinguish it from other fluids.
Where are the solenoids on a CVT Gen 2?
Once you have the valve body on the bench, flip it over to reveal most of the solenoids on the lower section of the valve body. The Gen 2 CVT has six solenoids mounted to the valve body to control transmission operation (figure 4): The Secondary Line Pressure Control solenoid is an unusual solenoid; it has the pressure regulator valve in its snout.
Is there a problem with the transmission valve body?
There are a few transmission valve body symptoms that keep you aware of failure activity of the engine. Most of them are quite noticeable. It is recommended that you should fix these problems as soon as possible. Then, your driving ability will be protected and gear changing will be smooth as usual.

Is there a problem with the CVT on a Subaru?
Their first attempt did not replicate the behavior, but they tried again and were able to feel it. After having the vehicle for a few days, they “re-lined the transmission” with no success at fixing the problem. The next step in Subaru’s troubleshooting was to replace the valve body within the CVT.
When do you have a bad transmission valve body?
Late gear shifts or general issues with gear changes are common transmission valve body symptoms. When the gearbox prepares to change gears, it will drop the RPM slightly. A bad transmission valve body probably makes the RPM spike for a moment. Whenever you experience these problems, contact your mechanic for a check immediately.
