I have my 2016 (configured as my sig states) throwing a p0871 trans code. trans temps have never been really high.
P0871 is an OD Pressure Switch Rationality fault

Only happens when climbing a hill towing. trailer is a 24x8.8x8 enclosed trailer pretty close to empty about 4500 lbs

Dealer is booked through the 21st to look at it (still in warranty) anything I can do to make it last till then? I am now in a position where I need to tow regularly and looking for a manual dually in the not too distant future.
