Tranny Prob. 97 GMC Sonoma
I need a little input on what to do next... My 1997 GMC SONOMA 4X4 Automatic Trans. has a trouble code of P1870 (Transmission Component Slipping) What is my next step.... It has been doing this for a while and I'm ready to get it taken care of before I have to replace the tranny. What do I do now?
