03 Automatic 350z Touring

Quick info: i had to change my RR Control Arms(Upper and lower), all Brakes, all Rotors, Rear Sway Bar, RR Axel, RR Hub Assembly, FR Inner and Outer Tierod, FR Hub Assembly, FR Lower Control Arms, after an accident i had

When i go from a dead stop, my car will reach 2000rpm, then it will not allow me to accelerate and flash SLIP until i let it die down to idle rpm's. After it gets past that stutter of going into 2nd, it runs perfectly fine till i come to a full stop and try to take off again. The only solution ive found is when i go to take off, if i turn off my traction control it wont let me slip then i can turn it off and were good, but driving like that is nowhere near safe or reliable for a daily driven car. I changed the TPS Sensor, thrn i changed the spacer back to a stock one, but it seems that the car still has issues trying to go past that point.
If anyone has any information that can help me with the situation it would be greatly appreciated, and i will try to answer any responses i get to solve the issue

And if i posted in the wrong forums or something its my bad, new to using the forums to post so its a little confusing to me is all

 

Wheel and tire setup?

Whenever you are troubleshooting ask yourself what has changed since "xyz" worked correctly?
Since you didn't include any pics my wild guess is you're getting a SLIP error bc wheel speed sensors aren't working correctly.
