Loosing Over Drive.

My car has started to loose overdrive i think. It does this odd thing sometimes when im crusing on the hiway at about 60 when it starts going in and out of overdrive and after a while i think it stays out of it. I cant recreate the problem, it seems to happen randomly, happened 3 times now. I'm sure loosing a gear is not a good thing, might be a sign of trannys upcoming death? It shifts ok otherwise , not that great does the long ford granny shiftls like it always did and acts crappy when its cold. car has about 165k miles on it its a 94gl with a vulcan and its an ax4s tranny.

So what you guys think? some stupid little solenoid issue or tranny is dropping dead? The fluid is nice and clean and synthetic i changed it every year which was about 10- 15k miles apart . I'm not going to invest gobs of money in this car honostly we all know its cheaper to buy a new taurus or something similar.

So what do you guys think?

my ax4n had the same problem at 81K but I also had a SES light and the OD off light was flashing.

Had the trans rebuilt, clutches were good. A lot of hard parts were discolored from heat but still in good condition. The culpruit at least in my case was a poppet valve in the valve body seizing in its bore.

The fix even though a full rebuild was done was, that the valve was replaced with the same valve from a AXOD non electronic trans because the ax4n's valves were made from a different metal than that of the valve body and as different metals do they corrode each other and it caused the valve to seize. Valve from donor trans is the same as the valve body and it has worked flawlessly for 18k miles.
mine intermittently would shift into OD, at almost 100k i have not had the solenoid got out ever.
