About 2 weeks ago I put a Danville 3794 STG2 turbo in the truck. ALso had Rob return the truck for the new turbo . Now my Trans keeps going in to limp and getting P0777 and P0700 DTC . Any help would be good.

I also changed the pan filter and Trans oil about 2 moths ago.

It has always shift hard from 3 to 4.
