I have a 97 Avenger the transmission is goin out and i need a new one with less than 100,000 on it ill pay at lease $500 or more im located in southern ohio, just hit me up if u have one you want to sell. And, its a V6.
If I were you I would go to exileracing.com, and buy one of their high performance trannys. Yeah, they cost more than you want to spend, but you'll get a better tranny than any stock one.
