i have a check engine code P1870 which says trans component slipping. drives perfectly fine except sometimes i will get a hard 1-2 shift. was told it might be a back TC switch so i replaced that and it was back to normal for a couple days but then it returned. my tahoe has 209k mi on it and i was told by the previous owner when i bought it back in oct that the tranny was rebuilt by the previous owner to him about 5yrs ago so it roughly has about 60k mi on the rebuild. the previous previous owner was a tech at a saturn dealership so i assume he knew what he was doing.
any ideas on what could be throwin the code for me?
