No Tcc with 4l80e
looking for some help. my car has a 5.3 with a 4l80e and i have no tcc lockup the trans works like normal in every other gear but no tcc. i am using efi live and with the commander the converter will lock up. but in normal driving mode it will not go into tcc mode. i need some idea's were to start figuring out this problem. i have went and turned off dtc's that i don't need the only dc's i have are p103/p103 maf codes being the car is speed density the codes are set to non emissions if i place them on not reported the car doesn't run correctly. and p0463 for a fuel level sensor. i cant for see these not allowing the tcc mode.
i have a brake switch signal to the pcm.
