Codes 0122 and 0123

symptoms:
auto transmission downshifts without notice to the point where the tires squalk, the rpms have not redlined by have jerked my head forward throughout the past several months.

It also idels high at times and shuts off at times while ideling.

I took it to transmission shop. He said codes 0122 and 0123 were throttle codes but could be contributing to transy probs.

But I'm new at Jeeps and I typically just throw parts at them and see what sticks
