This solenoid, along with the Torque Converter Lockup Clutch we also have listed, should be changed every 100,000 miles. When they fail, they allow the clutches to slip - meaning the gearbox will fail prematurely.
This solenoid controls pressure to all of the main clutches - to replace them is expensive and difficult so it's important this solenoid is kept in good order.

Replacing this part is easy - remove the sump pan, remove the filter and you'll see the valve block. Simply use long-nose pliers to remove the securing clip, and swap the solenoids over.

3 year / 50,000 mile warranty on this part.
