It really depends on a lot of factors...like how many shops in your area, and the value of a dollar in certain areas. In New York you're probably talking 2 grand, in Mississippi it'll be probably 600 bucks. Impossible for us on an internet site to let you know...as Vile said, get some quotes, they should be able to tell you over the phone due to everyone knowing what a th350 is. You can save some money if you remove/install, just take them the tranny.
