1997 FZJ80 Automatic transmission. Shifts smooth through all of the lower gears but won't kick down into overdrive. Overdrive button is broken, clicks but doesn't really do anything. No light on dash. Get up to highway speed and its sitting at 2700+RPM. If you touch in the main shift button it drops down and almost feels like it's dropping into overdrive. The issue started when the drive seemed to flutter in and out of OD when on the highway, but now it doesn't seem to want to engage at all by itself.
Recently snagged this thing so hopping in the middle to do some troubleshooting.

- Kickdown cable seems to be adjusted about as far as you can go. Some slack in the cable but not a crazy amount
- Checked the ATF. Looks clean enough to me, was reading a bit low after running it according to the manual. Topped it off and check again after running it and it's right within the Hot marks.
- It does have a 2in lift and 33s on it but I can't imagine that would impact this
