Just got a 1974 2002. I got the automatic for my wife. I really wanted the manual. The transmission shifts hard and when warm going from neutral to A (drive) screeches the tires. Their is also a very slow leak coming from the transmission at the seal where it contacts the motor. Not sure if I need to rebuild it, buy a rebuilt transmission, or what. Any advice would be highly appreciated. Also, where can I get a rebuild. Would a manual conversion be cheaper?
