Help with codes

[5969916Rhino]

My Yukon went into limp mode not shifting
out of 2nd gear. ( newer trans). Codes C0226,
C0222, C0265 came up/. I replaced both
speed sensors and the Electronic Break
Control. Still in limp mode and getting code
C0283 and C0287. (Also the code scanner
says that all 4 wheels are going 5mph when
stopped.

Hi and welcome! Real people, not actors here.

All the codes seem related to the ABS system only. I can't see how they could affect the transmission. Transmission codes start with a P (powertrain). Could be coincidental.

The EBCM sounds like it's having some problems getting sensor input. Maybe a connector is disconnected or the wiring is damaged.
