Frequently Asked Questions
What causes valve body scoring?
Contaminated fluid with metallic particles can score aluminum valve body bores, causing valves to stick.
Can solenoids be replaced individually?
In many transmissions, solenoids can be replaced individually by removing the valve body, without a full rebuild.
Should I use OEM or aftermarket parts?
For transmission solenoids, OEM parts are generally recommended for reliability, though quality aftermarket options exist.
