The bright light fitting is the same as the dim so take it apart fist to see how the cover screws off/on and the light comes out. Both the cover and the bulb are removed by a standard twist to the counterclockwise and replaced by a twist to the clockwise. Now to the dim light. You have to release the entire light assembly before you can remove the screw-on cover to reach the light. On the rear edge of the light unit closest to the engine is a white locking tab. Pull that tab up just to the point where it releases…pull too far and it locks again. Next, locate the other locking bracket which is a metal bracket in the center-rear of the light assembly. This bracket is held down by a screw. Remove the screw with a 10mm wrench. Lift the bracket just like you did the white bracket. You should now be able to pull (or pry) the entire light unit forward a little. Depending on the size of your hands this might be enough. If not, then you need to release the plastic bumper assembly to give you a little more space. This is done by removing two expansion locking pins, one that holds the little plastic strip down between the bright and dim lights and one that is located inside a rubber bumper on the engine side of the light unit. To remove these locking pins, pull or pry up the little tab in the center of the pin just like you were pulling a nail by the head. That should give you a little more space.

SOURCE: how do u add transmission fluid on a buick

The only way I know of to add transmission fluid to a transmission is through the same tube that the dip-stick is in. Add about 1/4 quart at a time. Usually, it is added while the engine is warm, idling in park or in neutral. It should tell you on the dipstick itself. Be sure it is on level ground. Do not overfill, or it will leak forever.
If the transmission level is low, then it must have leaked out in the first place. Try to find a leak by parking over night on fresh newspaper, and observe the paper the next day. If it is towards the front, then it might be the tubes going to the radiator, which cools the tranny oil right along with the engine coolant. If it is in the middle of the engine compartment, then it is the front seal, a major repair, so just maintain the level until the end of the car's lifetime. If it is towards the end of the engine compartment, then it is just an output seal, an easy fix by a competent mechanic.
Most transmission shops, as well as brake shops, will give you a free inspection. Sometimes, Wall Mart will too.
Good Luck.
