Transmission slips into second while shifter is in first
 

I recently had my 700R4 Rebuilt. First question: Is there a way to adjust the shifter cable? It feels as if is off just a bit. Second question: When I am manally shifting it, it goes into second while the shifter is still in first. Do I need to adjust the tv cable, or is this because the shifter cable isn't adjusted correctly???
It seems to be strong shift fine (maybe a bit soon) while left in drive. Last question: before i had the trans rebuilt, i used to get a second gear scratch. Now, forget it. Do I need a shif kit? Thank you!
