Fault code p1870 on 97 Bonneville Pontiac

Question

I have been to 5 shops that have no idea what this code is, and cant seem to find it any books. Any help??? PLEASE!!! Thanks =oP

Answer 1

.the obd 2 code p1870 shows a transmission component slipping.........any repair shop with a decent scanner and that wants to take the time to check properly should have been able to tell.   the problem MAY be a low trans fluid level, OR something electrical that is causing the clutches or band not to hold properly.  (internal solenoids, etc.)  a test drive by someone that is knowlegeble in REBUILDING and REPAIR shold be helpful......most trans shops just replace and are not always skilled at knowing how they operate.

Answer 2

Appears to be a transmission related code, although I am unsure as to the correct diagnosis. A factory trained technician could help.

Also, check fluid level and condition.
