hey everyone I have a question that may be tough to answer or maybe not, but I have an 88 SS and the 200r4 transmission is no longer in the car and there is a different one in it's place but I have no Idea what it is, it isn't electronical because the car does not run on a PCM anymore, so I guess my question is does anyone have a site where it shows common transmissions like this or does anyone think they might know what this is? the engine is the stock 305ci 4bbl V8

 

it would have to bea older th350 or th400 if its non-lockup

 

here is a pic of the pans of the th350 and th400
