My overdrive off light was blinking for about 1 month the stopped blinking. While it was blinking, when coming to a stoplight or stopping, the trans clunked when it down shifted from 2nd to 1st. Now it has stopped, but truck doesnt seem to shift into overdrive and stalls when braking to a stop at intersections or when just trying to get out of my drive way when I start my truck. It seems that it idles just below 1000rpm and really hesitates when accelerating at start. Any thoughts on whats happening? Thanks.

Sounds like you need to replace the overdrive button on the end of the shifter. This can be bought at most parts stores. Also check fuse number 6 and number 15 (5amp fuses). Hope this helps you out.
