2003 GMC Sierra 1500 5.3 Transmission Problem

[kkaupang]

hey, my computer is throwing out codes saying Shift Solenoid B, and TCC Circuit. The pickup wont automatically shift by itself, it goes into limp mode and defaults to 3rd gear, if i shift it to first it'll give me 1st though, also 2nd if i put it there. I replaced both Solenoids, new filter, new fluid, reset the computer, and also disconnected the battery for awhile to reset it, but problem still occurs. any ideas?

never mind i guess... i did find the problem though, it was a loose wire in the Dash Fuse box by the passenger door, wire was for the top ignition fuse, put the truck into limp mode, fix that and back to normal! hopes this helps someone out
