Anyone know what's wrong with my truck it's a 03 4.7 with the 545rfe I replaced all filters sensors Solenoid Pack and it shifts terrible and go into limp mode after 3 rd gear it has p0700 p01775 and p0876 does anyone know what's wrong with it thanks

 

Google those codes and it will tell you.

 

When did it start to shift "terrible?" After you changed the filters or before?
