You add fluid the same place you check the fluid.
At the power steering reservoir.
5 to 7 for a fluid change Add 3 to 5 for a rebuild.
In the same place as the dipstick is located. Use a funnel.
Master cylinder, upper firewall, driver's side.
The same place the transmission fluid dipstick is. Be sure that you actually need to add fluid or you can cause serious damage to your transmission.
7 to 7.5L of dexron 3
There's no need to "add" it. It's built into the driver's door by the window switch. There is a button that locks out the windows & the rear door locks. Push it and it lights up yellow.
Yes, that is a very bad idea. The brake fluid will damage the trans seals, and it will start to leak.
Down the dipstick tube.
Well... pull-out that rather long dipstick located in the back of the engine compartment, and add some transmission fluid. Make sure you check the fluid level with the engine at operating temperature, in park and on a level surface.
Attached to the rear of the engine is the transmission. There is a filler tube coming out of the transmission and it usually has a red dipstick that you remove to add fluid. Dexron 3 is the fluid to be added.
