HI im a Gbody noob, I have a 1987 el camino, it had the 5.0 v8 originally, and I believe it still has the original transmission. also im not sure if this matters but its one of the floor shift models, not column shift like most... I always thought the car had a t400 in it but after doing some google research this morning I read the t400s in these didn't have over drive... my car has over drive... I always thought the t200s were for v6 models only... is this a t700? how can I tell what trans I have?? I need to get a new transmission filter and gasket and when trying to order for my year and specs there's like 4 different types and styles to choose from that all say they "fit" my car... what do I order?? please help
