    Default Transmission identification 1983 V6 Cutlass Supreme

    I have a V6 cutlass (which the former owner treated like shit) so I am not quite sure which transmission it has. It was worked on before but I am not leaking transmission fluid (not from the pan) and have to find the leak. I just dont know which transmission I have on my car. I went to O'Rielleys and they have a th200-4r th250 and 2 other models. Is there a way to identify it?

    It appears I have a TH350. Is this common to have a TH350 transmission on a V6 engine? I was told that my car should have a th200 so I got that gasket (11 holes) but when I count my screws, its 13 and looks exactly like the TH350.

    You may also have a TH350C (later lockup version of the TH350).
    May have been replaced at one point.
