I had the same problem come up last week and took it in..after I checked here for comfort and suport. Heres what they did (right off the work order)
EEC TEST P0781 TRACE TO 2-3 ACCU LEAKING. ROAD TEST RUN ELECTRIC TRANS DIAG. PINPOINT TEST C TO 2-3 ACCU PISTON. R AND I 4R70W TRANS PAN AND VALVE BODY AND REPLACE 2-3 ACCU PISTON. ROAD TEST AFTER REPAIR. CLEAR CODES RETEST OK NOW. 5013
Anyway same symptons and this seems to have fixed it. Very cool that I had the problem, came here and instantly had an idea what was up b-4 the dealer looked at it.

Glad that there was a post similar to the problems that you had....since I made the first post, it came back on, they were going to replace the cylinoid, and then the torque converter....got my truck back yesterday after a 7 days in the shop, and they ended up putting in a "new" re-built transmission in it......not happy about that, but then agian I haven't been too happy with this truck either....but I am still a die-hard Ford man....nothing but the best!!!

Hi all, new member here....
I've been having a similliar issue with the O/D light blinkinng for almost a week now. After reading through this thread, I tried to pay more attention to when this is happening:
It does seem to be shifting harder than it should, especially down shifting. This morning on the ride to work, I could not get it to go off. I took it easy at first getting up to 50 mph, then I tried to make it go off(By nature I'm a casual driver). So I pegged the tach up to 3.5k and it still didn't go off?
Unfortunately I work pretty close to home, so I didn't have a great deal of time to try to recreate the issue.
It seemed last night that it was going off @ 2-3 gear shift is there some kind of sensor to check?
Thanks

My 97 F-150 has had the same problem with the OD light flashing but with a twist. My trans jerks when it shifts as well. I took it to the shop and told me to just change the fluid and filter. I did and it drove great for two days and then started up again. I thought maybe it was the trans heating up, but again you can turn the engine off and then on again and everything is fine. I'll be taking a look at the sensors next.

overdrive light blinking
i have a 1995 f150 mark lll conversion and the light started flashing a week ago but it stalls in first then i have to let off the gas a bit to make it shift into second and overdrive, plus it slams through every gear and if i let off the gas or brake in overdrive it wont shift back into it. the other problem is it slams into reverse and drive everytime, i dont know if i need new button or my trans checked out
