Allison 3000: If gear selected/attained display has an "L" is that telling me that I have low fluid? When first starting up it shows a "C" (for cold?) so I assume there is more info there than just the gear.

Those are gear codes. We receive both a text code and a number from the transmission. Text codes are the most common. They differ between OEMs and models but the are usually like P, R1, R2, D, D1, D2, L1, L2, etc. with P being Park, R = Reverse, D = Drive, L = Low. I have never seen C so not sure what that means. Maybe IRV2 or other forums might shed some light. If you find out, let us know here, ok?

Of course, it could be just an ECM programmer bug where they meant to send 'D' but instead sent 'C' 😊.

Mine's an Allison 3000 on a 2007 FCCC chassis, and I see the same as the OP. Most gears indicate, e.g., "3L" or "4L", etc... but occaisionally I'll get a "3C" for example. Don't know why the "C" vs. the "L", but the indicated transmission gear *number* always seems to be correct.
