Anything that can be done to get this out of limp mode so i can drive it home and to the shop? seems to be pressure sensor issue, anyway to get rid of the code?

I do not believe that is a transmission pressure sensor issue.
P0840, P0845, P0872/873 are the fault codes related to pressure sensor failure.
P0797 is normally a torn piston seal.

Piston seal failure.
I have the same code in the last year, went limp mode only using 1,3,5,R gear.

I opened mine valve a few months ago but, nothing is torned. I think the sensor again.
