Transmission Problems

Hello,



I have a 2000 Mitsubishi Mirage DE COUPE Automatic, and I am having problems with my transmission. Everytime it goes into first it always gives a jerk, and it starts to give a drag feeling. What can I do to solve this problem. And if I am going to change the transmission, can I use a transmission from a 1998-2001 MIRAGE OR 1998-2001 LANCER?

You could have a CV joint about to fall off. Somebody has to check it before it happens.
