: On the road and P0872

So I'm about 1000mi from home. Truck is running great, no problems. When I'm towing our travel trailer (7600#), shut down for fuel or whatever, on start up I get SES, read the codes and get P0700 and P0872 and then clear them.

No slipping as far as I can tell. No limp mode. Running fine.

Called a local dealer here and have booked an appointment for tomorrow am but I really want to be on the road again tomorrow so I'm wondering if I should really be worried about this or not?

Again truck is running great, no slipping, levels are good and no limping.

Should I be concerned?

Of course the dealer wants to run trough the diagnosis tree!!

Oh and I should mention this seems only to be happening when pulling the trailer.
