I have an 01 Gt and I believe that the 2nd and 3rd gear synchros are goin bad.Would it be cheaper for me to have it reapaired or replace the whole thing.If I did replace the tranny what others will work in my car,I have the Tremec 3650 now and I dont race,and its still basically stock.And what are some good online sites for trannys.I have knowledge of cars and most of time do my own work but I have never torn into a tranny before,is this something that I shouldnt even look into,I mean trying to do the rebiuld myself.
