1968 camaro stock ls6 zo6 motor and 4l60 with yank 3600 red line clutches and beast sun shell , ssp wiring harness ecm is a blue and red connector, just got the car together and brought to tuner to find out car had no speed signal wire , he moved a few pins and got the signal, now trans will start in 1st for fist time and then shift second then it goes almost into limp mode nothing. then u come to stop and even if you put it into 1st it feels like starting in second or third. No codes tuner thinks clutches or wiring, any help please. ''red connector to ecm pin 39 and 40 have pins but no wires could this be my problem?''

I'm assuming you are using a 99-02 fbody harness. Pin 39 red wire goes to the cam positon sensor and Pin 40 black wire is a ground. Fix those and see what happens. When the trans goes into limp mode all you have is 3rd and reverse.
