2004 Buick Century Q&A
2004 Buick Century Question: My car is starting not to shift right.
I had my transmission rebuilt about 3 years age. My ABS light is on and my no trac light is on. My car is not shifting right. Sometimes when I would stop and shut the car off for a few minutes it would start shifting again. Could the cause of that be the transmission again or could it be something else. - kjseay
yes scan codes and post so we can adv.abs codes can cause many issues - globalhelper
it could be the transmission modulator on the trans,and that is not expensive... - jpspearman
