would 4l60e tcc lockup wired wrong do this?
would 4l60e tcc lockup wired wrong do this? 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
''Update'' fig out buddy just wired tcc lockup wire right to my stock 68 camaro brake switch .so when brake pedal is pressed it send power to wire thinking that is what is putting trans in limp mode. info please if this could or could not be my prob. going to get a relay today.

Is this a 4L60E controlled by the PCM, or is this an ancient old 4L60 controlled by a governor? I assume you meant to say it is a 4L60E. In that case the PCM controls the TCC and you must make sure the trans cable is correctly wired to the PCM and remove the crazy wire to the brake switch.

As I read S10PRO's post, someone did wire the TCC directly to the brake switch, which would be a dangerous hack.

I understand what you are saying, but "Wired through the brake switch" might confuse someone. Only the PCM is wired to the TCC; the brake switch sends a signal to the PCM, but there is no direct wiring.
