Hey all! I’m new here and new to working on transmissions but I really wanna learn! Please excuse any weird wording or me not understanding any terms you guys say. I have a pretty solid understanding but still learning 
With that being said here we go!
I own a 2012 Chevy Malibu with the 2.4L ECOTEC paired with a 6T40 Gen 2iirc.I have some weird issues with shifting.
When the trans is still "cold": Shifts up fine with very little jolting. Downshifting from 5th to 4th is rough and sometimes 3rd to 2nd is rough but not too bad..
When the trans is "hot": 1st to 2nd is normal but tonight there was a delay however, when the trans goes to shift into 3rd I loose power or "falling out of gear?" until it either bangs into 2nd or 1st. The shifts during this period are extreamly harsh and happens a few times on some occasions....
Shifting to drive has a few sec delay
Codes:
P0700-Limp mode/gen failure
P0747-Pressure control solenoid A stuck ON (Just happened tonight)
P0797-Pressure control solenoid C stuck OFF
Heres a vid of what happens when its hot:

Recently when shifting into 4th it feels like it’s slipps a tiny bit then catches. I believe the failure is In the TEHCM and or Valve Body. I’m planning on replacing the TEHCM and valve body as well as the trans filter in 2 weeks but I wanna be 100%. Any opinions? Thank you all!
PS sorry for any formatting issue, I’m typing this on my phone before work
I just realized I posted in the wrong section. Mods, can you please move this to the correct section
