* Automatic Transmission: You'll likely need to access the transmission fluid through a fill port on the side of the transmission itself. This often requires a specialized tool or adapter to reach the correct fill level. Do not attempt to overfill. It's best to consult your owner's manual for the specific location and procedure, or take it to a qualified mechanic.
* Manual Transmission: Manual transmissions typically don't require routine fluid changes unless there's a problem. There isn't a readily accessible fill point like an automatic. Again, consult your owner's manual for any information on this and seek professional help if needed.
In short: Consult your owner's manual for the precise location and procedure. Improperly adding transmission fluid can damage your transmission. If you're unsure, it's always best to have a mechanic perform the fluid change.
