I have an 01 GT automatic and my buddy (who is car knowledgable) says my transmission is going and need to get a new one. First off the problem. When ever I acclerate there is a "clunk" noise. itts only when I first accelerate from a stop or I floor it while already moving. So what is the noise? and if it is a problem. Since I am assuming I have to replace the transmission. What kind should I get? SHould i get a new torque converter should i do a stall converter. I know I have a lot of questions, I just dont know to much about cars. Please help.
