P4701. Allison 3000
Been running fine, after about 400 miles today it lit the Service Transmission light.
The code was a P4701. Allison/Cummins 400HP on FHT chases.
Any thoughts? I've done the Google on it and it did go out when I shut it off and restarted.
Never had a tranny problem, did a fluid/filter change at the dealer 3k miles ago. Any relation maybe?? Trans temp was 196* when it had the code.
Edit: I got that backwards on the diag flashing. It's P0147.
Allison support helped me reset it and go through the scan again, it did not come back. See how it goes on the road.
