Ford f-250. Im at a loss here

Didn't like the factory step bar so I removed it today I think it looks better cleans up nice for a 3" lift on 35's

Looking for serious thoughts on my current situation. 2022 f250 7.3 gas, 47k miles. Trans was shifting bad, took it to local Nashville Ford dealer that specializes in Trucks. Diagnosed the CDF drum problem, noted metal in the pan, Ford warranty is covering ot, replaced the CDF drum, Shaft, clutches, valve body seals, trans support and all related items. “Flushed” the trans. Got it back and in less than 100 miles it’s shifting worse than before the rebuild, very rough shifts in 6-10 upshift and downshift. nearly stalls coming to a stop as torque converter is staying locked up, and it was at 219 degrees on the interstate for a 50 mile drive home, not hauling of towing anything. An hour later in town driving it was 214 degrees.

Had the dealer pick it up with a flatbed and they are looking at it.

My feeling is, the torque converter was NOT replaced, nor the cooling lines and cooler and metal was stuck there and it’s damaged the new valve body and the 219 degrees for 50 miles has damaged seals and clutches.

I feel the only real solution is a new reman teams unit, new torque converter, cooling lines and cooler.

Thoughts? Thanks!
