figures i start buying parts for a major build and now my car is pissed...okay here we go. i figured i had a tranny problem because the tranny wouldnt upshift but idk. put a little fluid in the tranny and then i realized that when i reach 4000rpm it feels like the cars computer starts killing the power and when i get to 6000 instead of shifting the car hits its max and limits rpm instead of shifting. what could this be?
