I’m sure that this topic has been discussed before, probably several times. This is for the most part, a hypothetical question and I doubt that I would ever do it but if health problems made it necessary, maybe. So, an automatic transmission behind a banger motor? I know that automatic transmissions take some torque/horsepower to operate and that would have to be taken into consideration when choosing a transmission. I’m thinking that even the most efficient automatic would be too much for a stock motor but 80 hp is not that difficult to produce. Rear axle ratio would come into play as well if a guy really wanted to do it right. I’m thinking that most likely a power glide is the most efficient of the automatic. A power glide being only a 2 speed that would come into play although on the other hand, the slip of the torque converter would help mitigate that. Obviously, an adapter would be required and so the availability of one could dictate transmission choice too.
