It is hard to sell a car with a salvage title, unless you are selling at give-away price. The reason is obvious. The title gives people an impression that the car was in a major accident. If you spend money (e.g. rebuilt tranny) fixing the car, it is likely that you are not getting the money back when you sell it. If you decide keeping the car for a long long time and you find a good salvage car with good price, why not.
