" check transmission"
I checked trans' fluid level , (not running) and it was at the top end of the cold section on the dip stick..
My closest Allison shop is 110 miles away in Las Vegas and the RV dealers here in Bullhead City "only work on the hotel part of the RVs"
I have read that some transmissions need a 5000 mile "first filter change"
could this be triggering these warnings already ??
The rig drives and shifts normally, what damages could be done ??
Thanks for any help....

Update for all that helped me on my check transmission alarm light problem:
SHOUTOUT TO WW WILLIAMS IN LAS VEGAS- Authorized allison shop!!!
I drove Tug to Vegas 110 miles, had one code throw and decel to 50 mph from 65 mph.
turned off reset code from dash and made it to shop. plugged in code reader gave a code that means TCM short ( transmission control module ) by the way its behind the driver seat on a Wraith 32W...
outside harness tested good ( or International would have had to replace that, so tranny opened up and INTERNAL WIRING HARNESS FOUND TO BE SHORTING, SO REPLACED.
ROAD TEST and drive home all good!!! MPG before fix for 350 miles 9.3,,, MPG after fix 11.5 for 110 miles !!! no difference in grade ... pulls hills much smoother with final gears locking up better..
Of note they said the spin on filter does not need replaced anymore at 5000 miles...
