I have a 1986 iroc z28 I bought two weeks ago. It has a 350 with a 700r4 tranny after bought it it started to act like it had a stall converter it you rpm real real high not shore exactly what rpm gauge doesn't work I looked up info found out tv cable was frayed so I'm changing it out plus the pan and flouid but while I was under there wondering if I could tell if it had any mods done to the tranny while I have it apart?? Anything will help me this is my first camaro thanks
