The truck will not back up when you put in reverse it flashes the line below the R. I transmission is full of fluid and does not stink. The color is good on the trans fluid to
Hopefully Mike L. will chim in with better information/solution but from looking at my ATSG book.
P0876 is "Reverse Pressure Switch Circuit Stuck Open"
P0871 is "Transmission Pressure Switch, Solenoid E Circuit Stuck Open"
and P0743 from searching looks to be a bad F trim solenoid.
So looks like you'll need to pull your transmission pan off and test those solenoids and look to make sure you're wires/connections are good I would think.
Or take it to a reputable allison mechanic that'll look at it.
Where are you located? There maybe someone in your area that someone on the forum could recommend.
Good luck

I am located in south west kansas by dodge city. I am going to pull the pan and ohm the solenoids and check wires.
The meaning of the codes were posted, as well as some suggestions.
Did you check the wiring? Have you removed the pan to check the condition of the solenoids? While you are in there, how does the internal filter look?
