I have the ATI Treemaster 10"-3400 stall converter that I bought from Charlie Evans,he stepped up to a 9",but I've read little about the Coan converter that seems to be a great converter.What i'd like to know for any of you who've had a Treemaster converter and have switched to a Coan,is there a difference and which do(or did) you like more.My combo has been posted before,and trust me...I'm trying to take baby steps,but reading all the benefits through all this wealth of Buick knowledge is like going into a candy store with a :dollar: ,and everything costs a dollar,it's kind of hard to make a choice.Should I go to the Coan Converter website? Thanks,Jay B.Britt,Jr.
