Transmission started slipping code p0741 came up i filled fluid up and code went away but still slipping. RPMs at 3,500 at 55 MPH acts like not changing gears tried manually shifting and acts like it's not changing gears. Now pops up code p2771.

So I would try to service the transmission with a new filter, and replace the TCC control solenoid, also while the pan is down check the fluid for a burnt smell, this will let you know if the clutches are burnt and it needs to be rebuilt.

DTC P2771 - 4WD Low Switch Circuit High

Please start a new thread for the p2771 code which is for the transfer case and we only handle one problem per thread. Here is the location of the TCC solenoid. Check out the images (below). Let us know how it goes.
