Well, like the title says, I have no overdrive. It was working fine all day until i left my friends house to drive home and it wouldn't shift into o/d @ 50, i tried for 20 minutes, to see if it would go, and it didn't. Everything else seems fine, no shuttering, downshifting just fine, i can get into the throttle with no problem, it just doesn't want to go into o/d.
Could it be a stripped 4th gear??
