i have a 2004 Dodge Neon SXT 2.0 L automatic. The transmission needs to be replaced so I'm loking for a used one. What years are compatible, how much work is involved, will the computer need anything done to it, what should i do to the new one such as the torque converter seal, special tools required, etc. This will be my first time doing this so all info will be much appreciated. Thanks in advance and God bless
