Hi everyone


We have done like7 trucks with 4l80, then two of them (they have lsx engines 427 and 454) are throwing this code out of nowhere.
we tired using a new vcm and it didnt work
the code appears at the drags when using 4x4 , we are braking to get on the stall or inmediatly when you relase the brake... I have some candidates like:

- ABs control failure or going nuts
- input or output toruqe on 4l80 being maxed
- throttle body from corvette doing something funny

every pinter, comment would hlep me..there are no many people to talk in mexico about this
