Problems after a shop changes transmission oil and, pan , filter

Fault code P1DA0-00 on Chrysler, Dodge, Ram, or Jeep vehicles indicates an incorrect gear ratio or an internal failure with clutch A, B, or C detected by the Transmission Control Module (TCM). [1, 2]

Went into limp mode after I launched it. Was shifting funny. Then got stuck in one gear. Pissed mu 36k mile Trx has issues after the slam fluid change. They probably under filled it.

the lead tech told me the dude that swapped it just drained 6 quarts and filled 6 quarts without the proper procedure of running it through gears etc.

Now he’s going through the procedure of adding the proper amount of fluid. He went to the dealer to buy more fluid . lol

I gave them 8 quarts to begin with. Idk what’s going on but if it keeps shitting the bed, they owe me a new transmission.
