Tranny Slip code with SES light car drives fine but it just doesn't shift right from first to second, its been like this for awhile and I can't seem to get an answer is it a problem that should be fixed ASAP or is replacing the tranny i better idea with an HD verison, it happned last year when i was spinning in snow up to the door ledge

i thought there was only one? i know is has to do with one of the sensors catching a slip and ever since then hasn't gone away i'll pull the code again tomorrow and post it

I know this is a little old but heres the code P1870, Defination Trans Component Slipping? so is this a bad thing or a someone screwed thing :?:
