O/D light blinking sometimes

[boomerm]

I have a 1999 explorer with a 5R55e trans 180,000 miles. A few days ago the O/D light started blinking. The truck does not shift oddly or slip. I have noticed just before it happens, the trans seems to search for lock up slightly. It does not happen every time the truck is driven and I have taken it to two trans shops with no codes found. I suspect either the valve body gasket bad or the trans temp sensor / wiring harness is bad. If I take it to the dealer for them to pull the codes, I will have almost as much in the diagnostics as buying the new parts. What do you guys think? Any help would be appreciated.

Same thing happenen to me at about the same miles. Got a new valve body for $167 this had all the upgrades rebuilt servos and the glued on gasket. Also need trans filter gasket about 7 or 8 qts of trans fluid and lots of paper towels. About $225 this way.
