I have a 2005 expy with 166k on it. Today is a very wet and rainy day, on my wifes way home from work today she said she spun the tires on acceleration from a light, no big deal I thought. I took it out to go get dinner and on my way home I noticed the O/D light started flashing for roughly 30 seconds then cut off. got home, checked the fluid, all sensors and pigtails for a short and nothing. went to take it for another test drive and now the light comes on the second I put in gear (drive only), and consistently flashes now. The transmission is only 10 months old and replaced all sensorsbtw. I haven't tried pulling codes yet as my shop is closed on the weekends and of course the one time I don't bring my scanner home I have an issue. I'm going to wait till it cools down and see if it only happens at operating temp. I am in no means a transmission expert (I personally hate transmissions) but I do have a lot of mechanical knowledge as I do do this for a living. (Ford and chevy's keeps food on thetable for sure lol) but any insight would be appreciated.
