2017 camaro ss 6.2/8L90 swap will not move in any gear

hello everyone, new to gen V scene and having issues with swap into 1956 chevy. Looked at a local swap a friend done that they could not get to run. Two other individuals had already been involved in trying to get to run. Turned out the VATS was not completely removed or at least the did not perform write entire. After applying OS VATS patch, disable fpcm, and disable the starter diag and performing a write entire the motor fired up on second rotation. Thought things were on downhill slide, however when car is put in any gear it will not move. Any gear other than park it is like it is in neutral. While connected in the scanner can see that it recognizes each gear but get no attempt to move in reverse or drive. Does anyone have any ideas?

Just wanted to post an update, while checking it over the weekend and logging gear selection and a number of other transmission channels noticed all gears were commanded and recognized. Also happen to notice line pressure would go up then to 0, asked the installer if it was full of oil because it was not holding constant pressure. He said it was never broken apart from wrecking yard but would check on Monday. Got a call this morning and sure enough it was 5 quarts low on fluid and will now go in gear and move
