Default Transmission problems after replacing transmission solenoids

2005 Chevrolet Equinox 3.4L FWD - Was experiencing hard shifts and delay in going from park to drive when vehicle would get warmed up. I replaced the 3 linear solenoids and 5 shift solenoids. Now I am getting codes P0734 & P0735 4th & 5th Gear Ratio problems, going into limp mode, and reduced power.

Did I do something wrong? Prior to this I was also getting ABS and traction control lights and a front right wheel speed sensor code. I have replaced the wheel speed sensor twice and installed a new hub. Could there be an underlying issue like the input and output transmission speed sensor? Or did I screw up the solenoid replacement? I am fairly certain I connected all wiring properly.

I do still get cruise control so maybe it's not the output sensor? I am really in a bind here and not wanting to go through replacing solenoids again especially if I don't need to. Can anyone help me with this?

Thanks in advance!
