Two problems related to overdrive light on have been reported for the 2005 Mazda Tribute.
Overdrive Light On problem
1 While driving and comming to a stop at a light the car stalled while using the air conditioner. This happened several times, so I stopped using the air until I could bring it in for service. The next day while driving at 45 mph I noticed the rpm's increasing with no increase in speed. I also noticed the overdrive light blinking. I pulled over and the car was in neutral no matter where the shift selector was. I turned the car off and after 5 min. Restarted the car and was able to shift into drive. After about 100 yds , again the trans shifted back to neutral. Again I pulled over shut off the car and waited 5 min. I continued this procedure until I got home about 5 miles.
