2001 ranger trans. od light flashing and not shifting into 3rd. gear
the problem is the speed sensor on the rear differential. I have had this problem on my last 3 rangers. If a ashop repairs it cost will be around 250.00. You can buy the part at O'Reilly's for around 80.00 and two bolts mounts it with one plugin.
it also will not let the cruise control work either
