Transmission problem
2003 GMC Sierra V8 Four Wheel Drive Automatic 145000 miles

My truck (a duramax diesel with a programmer installed) has recently started sending out trouble codes and acting really sluggish if I push the accelerator to the floor. The codes are P1093, p1621, p2227, p2228. I originally thought it was my transmission going bad but with the codes starting to come out im not sure. Do you have any thought on the matter?

Do you
have the same problem?
