Ohhhhh OK! Well I was under the impression that it needs to be checked since its NOT, and yes I'am using a PRB Base map on this 2003 Accord 5 speed tranny.
Does the 2003 Accord 5 speed transmission have the same signal as the same year RSX then? Thanks

If you don't have an 02-04 RSX transmission then you don't need to check that box. Adjust as needed until the value is accurate.
