It might have been flashing because the transmission was too hot. Heat is the arch enemy of the 4R100.
Let everything cool down and see if the light doesn't stop blinking.

Hello Guys, Thanks for the response. I did wait awhile, un hooked trailer and was planning taking to auto Zone to read the codes. When I cranked it, there was no light, took to Auto Zone and said no codes?? So I drove today another 350 miles with no problems. Maybe it was heat, I was driving through Dallas on a Friday Afternoon about 3p.m. and that would make anybody hot!! Have 188,000 on 99 F250. Did replace transmission seal a month or so back and then changed fluid again. Seems to be O.K. When trying to get seal replaced everyone wanted to rebuild the transmission. Never have yet and still going. thanks for the responses. Sure good to have Ex Ford transmission guys respond. I really and truly appreciate your time. Wanting to repay the help. Thanks again. Dave

There is a trans code stored in the computer's memory, unless Autozone cleared it for you. They don't have readers that can read Ford trans codes, but their readers CAN erase the codes.

Hello Mark, At Auto Zone, the codes were not erased. I had the scanner and saw that option but did not do it. So what you are saying the code is stored in the computer? My transmission seems to be O.K. I just do not have the cash to have it rebuilt so keep hoping for the best. I have had it since new, always changed the fluid and filter myself and the torgue converter every time. Have been using Amsoil synthetic. I know on this sight that brings up 40 pages of reading. I also pull a 35 foot 5th wheel even though lately I have not been pulling it. I have changed the water pump from instructions on this site. I am very happy to get the info here. Again appreciate your input and assistance. As mentioned earlier, I had a problem finding someone to change the seal on front of the Trans. When I did find a guy he did a great job, works at a dealer ship, but did this on the side for $125 plus part. Said he checked u joints and so forth? So that is where I am today. Was sure glad to make it home, about 1100 miles in a week. Thanks again, Mark. Dave

The code will stay in the computer's memory for about a month after the last time the light flashed. It's still there, Autozone can't read it. A Ford dealer can, or a good indepedant shop could, too.

If you have a trans over temp code you need to change the fluid ASAP. when the fluid gets to hot it will break down and cause more damage in the long run.
Check your trans cooler, It may be full of bugs, mud and other gunk that is restricting the air flow.

KRDisesel, Thanks for the info also. Will check what you said. The fluid was just changed less than 500 miles and Synthetic but will check the code and see what happens. Thanks again. Dave

The scanners AZ uses only read generic codes (0001-1000).
Most, but not all, of Ford's tranny fault codes are "manufacturer-specific (1001-1999)". All it takes is a little bit better scanner than the ones that AutoZone makes available to customers.
