Change transmission oil, I drained transmition oil instead of motor oil, I cannot find fill port, not in manual. Also how do you reset oil change warning

Hello, there is definitely a fill plug. You may need to obtain a shop manual to find the location. It's not terribly easy to find because it's really not intended, apparently, for the casual vehicle owner to do this kind of service as it requires specific procedures and processes to follow to fill the fluid properly. You may be best towing the vehicle to a shop near you. It could be money well spent to prevent a major expense of transmission replacement.
