Ok I have a 2000 chevy silverado 5.3L 4x4 Z71 and it's really pissing the F off. I put a code reader on it and the stupid truck keeps reading circuits and solenoids. I'm always getting

-shift a,b solenoids,
-tcc pulse width modular circuit
- tcc circuit/open
- and O2 sensors.

Why is it doing this? I hate having to put so much damn money into and then I gotta fix another damn thing. Altogether I've put twice as much money into it from how much I bought the truck. Every shop I take it too says it's just minor. And I can do it myself, well I dont wanna do it myself I just want it over and done with.

Some one help me please. I got the codes that keep coming up too. I went and purchased the Haynes shop repair manual and circled all the codes
