Archived 2017, 6000 miles Transmission Issues

[423Indian]

Ram 2500, 6.7 dodge transmission. Truck shows check engine light, dealer said it was software, re flashed. No help, when cold truck will not move acts if wheels are frozen to the ground. Seems to do better if I shift r back to D a few times. Barley moves then grabs and jerks you back in the seat.*
Was in Jacksonville, Fl not a single slip all week. Light goes off after a few days . Tech said pump was producing proper pressure, computer calling for incorrect pressure.*

Fluid good

Two week wait to get it looked at, hard to do without it for two weeks

Any suggestions appreciated*

If the dealer tech could not figure it out on his own he should have opened a star case to get asistance

Thank you, what is a star case?

STAR is the technical support group in Detroit. Do you know what fault code it set? Did they manually check the pressure? I'm thinking the line pressure sensor may be bad as I don't see how the transmission can have the correct pressure but the controller isn't asking for the proper pressure.
