What are the probable causes of DTCs 12-01, 21-01,61-01,83-01,86-01, and 112-01?

SOURCE: no reverse. What are the probable causes of DTCs P0700 and P0780?

I own a 2003 ODY & frequent ODYCLUB.com forums for answers.
General opinion is when these trannys go out, it happens quickly.
But, it never hurts to know your issues and options before taking a dealer mechanic's word.
1. Codes for Low transmission fluid: P0730 & P0780
2. P0700: Sorry, but a dealer has the HONDA diagnostic tool to find the real problem code. P0700 is a generic "transmission error" code used by after-market diagnostics.
3. Check if your "D" is lighting up on the shift indicator.

Note: Always check for healthy orange colored tranny fluid before re-filling. Black is BURNED and needs replace & might indicate clogged screens or worse.
