Hey guys i just bought a '97 4x4 ext cab s10 automatic trans and i love it. the thing is on the way home from buying it it would only go into fourth gear upon letting off the gas so much it would slowly decelerate and going down hill it would go into fourth also. other than that it shift great, there is not metal or shavings on the dipstick and the fluid is very clear, like new fluid. then about half way home "service engine" light comes on so i have it checked at Advance auto parts and its a tranny code P187 "manufactures code". it gave me no bad part info at all. so i had them erase the code and it went into fourth fine after that even under acceleration it didn't shift into third, but once i turned around it starting doing the same crap of staying in third.
I am at a loss as to what the heack is going on
