    I have a short tailshaft 73 TH400, code B-S. Can anyone verify it's a 455 GS trans and what type of internals it has (ie 6 disc clutches, good valve body, etc)?
    Thanks

    My Turbo 400 book says it is for a Buick Century and Regal with 455's as I believe GS was only an option. You need to check a 73 Service manual as that will give you the internals info.
