Default 99 auto to W58 WEAK first gear

I bought a sc300 super clean interior and exterior second day driving trans broke so **** it manual swap. I just got everything in yesterday and IT RUNS!!! Not very well tho. Basically perfect except for 1st gear. In 1st it feels like the engine is limiting everything. I can bearly get to 1k rpms even when I dump the clutch. On hills it has stalled with the pedal to the floor. When I shift to second it comes to life and let's me drive normally. Any ideas to what's causing it? Only janky stuff is the NSS being glued in the neutral position. As well as one of the VSS being nor connected. (W58 had a manual VSS while the auto harness wants a magnetic sensor)
could it have to do with TRAC/ABS how do i cleanly disconnect those systems?

Default Theory

I think it has to do with my gear selector stuff. I need to get the car to think it's in drive. There is a really good forum on here with all the wiring and stuff but the guy sold his sc300 without getting us pictures. If anyone has this figured out pictures would be a MASSIV3 help
