Greetings to everyone here, my name is William and its a honor to be part of such an awesome group of "G" body enthusiast! Its my passion and has been for most my life. The 78 79 80 "A" body cars and the 81- 1/2 year 88 "G" body cars represent , to me, the last era of awesome rear wheel drives to ever come out of GM. My passion is mostly with the Buick turbo's, early models right through to the last of the great 87 Grand Nationals. While Im typing away at this moment, i would like to ask if anyone could help me here answer a question. I have owned ONLY automatic "A" and "G" body vehicles, I have since acquired a 4 speed 1978 Buick Century Sport Coupe car. Could anyone tell me what model transmission this would be? Any help would be very much appreciated!! Thanks in advance! Looking forward to making some new friends on here for sure 🙂
