Transmission control solenoid location on Buick Century?

On Buick century ,there are many solenoids and on your transmission they are behind the side cover of the transmission.

To get at them you need to remove the transmission to get the side cover off so you can access the valve body.

First you will have to inspect and confirm which solenoid is faulty.

Always get branded parts,instead of local cheap auto parts.Branded parts are bit costly,but they last long then local auto parts.Replacing solenoid is not very difficult, but testing the solenoid is bit time consuming.

Thanks.
