I was wondering if I could get some help. I need to change the torque converter in my 96 GT and I have never changed one before. Does anyone know if the one that AutoZone sells will fit the 4r70w transmission? Also I was wondering what all will be needed? I was also going to change the at filter and convert the fluid from mercron 3 to 5 so I was wondering what the easiest and best way to drain all the fluid is? Then lastly I have to replace my rear main seal. So I was just wondering what kinda job I am looking at. If anyone could give me an idea of what I am getting into and some tips I would greatly appreciate it. Thank you all in advance.
