I ahve a 91 accord my Sport light came on last while I was driving, then went off. Then start blinking so I stopped pulled over and turn my car off I was frustrated so I waited for about 10 min started my car again and continued home but the light will NOT stop blinking now..Any suggesstions on what I need to do before I spend tons of money at the Transmission shop. Is it worth rebuilding or just buying a new one..
