The O/D lights blinks about every few days then goes out. While blinking, shifts are very harsh, but it does shift. It happened yesterday and when I started out today, the light was constantly on and there was no shift to 4th gear. After I drove it a while, the light went out and the tranny did shift into 4th and the shifts were smooth. The CEL light is also on.
I noticed in the FAQ, if the CEL is on, then a trouble code should be stored. I am going to Autozone to see if it can be retrieved.
What has been your experience in this matter? I will search the forum history later.
