I need help identifying this trans trying to buy new tail seals and new slave cylinder I believe it's a tk5 but not positive it's a 5sp with over drive slave cylinder is in the bell housing I also need to know the correct amount of fluid and type to put back in it's a manul trans

 

E57A-7003-DA part number is a Toyo Kogyo 5 transmission(TK5)

The TK4 and TK5 used 80w gear oil, should be about 2 quarts, I think 1.8quarts is spec

The 1988 and up M5OD-R1(M5R1) 5-speed used ATF, and these do not have detachable bell housings.
