2001 Rodeo Manual Transmission-Need Help w/ Part ID
 

Hey everyone, I just bought a 2001 Isuzu Rodeo and I’m doing a little work on it. The manual transmission has what I’m calling “inspection ports” where you can see the clutch and other transmission internals. There are 2 “inspection ports” that are missing covers. One port has the gasket still stuck on the side of the transmission. WHAT ARE THESE COVERS ACTUALLY CALLED? All my google searches, auto part store calls and questions to friends have gone unanswered. It can’t be good to have these ports open to the elements, I think if I don’t fix this I could be causing premature wear on the transmission. ANY help on this is appreciated! Thank you for tour time
