i need advice if i should get a motor and manuel tranny for my car. dont get me wrong it has over 300,000 miles on it but it still runs like a champ and shifts fine for an automatic but i plan to keep this car for a while any suggestions.

 

Don't touch that thing. Run the wheels off it. My experiance with car with alot of miles is messing with anything major if you don't need to just disrupts alot of other parts.
