4l60e tcc locked up ? I hope someone can help me out. I have a 2002 5.3 with auto trans swapped into a 94 trans am. Right now the only wires I have hooked up to the car from pcm are fuel pump control,serial data and tcc switch wire. The rest are wired to a seperate fuse panel. My issue is when in gear any gear I have to apply the brake pedal to keep the car from moving and yes I moved the damn idle screw, I really wanted to drive it and was hoping the problem would just go away.😕 When I unplug the trans plug I don't have to hold the brake ,but the car starts out in 3rd . Also if I release the brake when in gear the tcc feels like it releases at 1 or 2 mph. So I checked all my grounds checked tcc switch also took tcc switch off pedal and drove around pressing and releasing button , no change . with everything plugged in the only codes I get are 449 , 452 evaporative fuel valve issues. Another thing, looking at lt1 swap site he says that pink wire on c100 pin c needs power I don't have a pink wire on c100 and pin c has a factory nub in it. And I can't find any wires disconnected, frayed or pinched . I am thinking I am missing some kind of control module for the trans, besides the gear selector module or could it be that I don't have a after cat o2 sensor. Any help would be greatly appreciated.
Sounds like the converter is just tight? Is this the stock trans and converter from the car or is it a swap too?
Afaik If the TCC was stuck on the engine would die. Its like a clutch in a manual car. Stock it only locks the tcc in high gear, it will bring the rpms down kinda like another gear.
The pcm controls the trans too so there is no other module that im aware of. The pist cat sensors do nothing but tell the pcm if the cats are working or not
