Problem here 5.4 2V

Hi Brothers in grease ~ 2001 Lariat 150 ~ 5.4 ~ This morning started for town ~ overdrive light was showing: OFF ~ engine struggled to move out from a stop ~ the check engine soon light came on ``` What do you think ~ sure like to hear ~ I'm going out to look for a vacuum hose is off the modulator ( tranny )~ if the is a vacuum driven modulator on this ~ first sigh of trouble ~ seems like out of the blue ```

My code reader is down at the lower ranch ~ damn ```

I checked the ATF ~ ashamed to say I had not checked the ATF ~ just got the truck ~ the ATF is just on the bottom of the stick I'll top it up ~ if that the problem ~ I'll change and filter ```

Well wasn't that low on ATF ```

What I have is the dreaded Blinking OD light ``` I've read the thread on Blinking Overdrive Light ~ I'm going to change the Transmission filter first off ```

I don't have the truck here it's at the upper ranch ~ I'd like to get the filter and oil before I go back up Sunday ```

2001 Ford Lariat 150 - 5.4 would that be a: 4R100 trany ?????????

Thanks

Could have had either a 4R70W (U) or a 4R100 (E). Check the certification label in the drivers door jamb.
Changing fluid and filter is not going to fix the OD light blinking. Get the codes read. Anything else is just guessing.

Also, you may get more involvement in your threads if you don't use weird punctuation.
It's creepy and makes me want to go wash my hands after I look at one of your posts.

Never thought of it that way but good point even if a bit humorous.

The OD light blinking is a code of sorts relating to the transmission operation. Counting the repeating flashes will reveal what DTC has been triggered. This should be a pattern of flashes something like one flash, a pause then three more flashes---and the whole pattern repeats itself.

Also my guess on your transmission is a 4R70W or possibly 4R75W----that light duty and year of a truck might not have received the 4R100 but as suggested read the door label.

Nope. It just flashes.but does not communicate any fault codes. You have to use a scan tool that includes manufacturer-specific codes reading support to pull all of the possible transmission-related fault codes. A cheap code reader isn't going to cut it.

Thanks for coming by, I was thinking if the return filter or in pan filter is restricting the flow a Sensor might shut it down and put it in Limp mode
Over drive OFF light on Shift **** light on .
The truck is at the upper ranch I'll take the code reader up there Sunday , there is a Check Engine Soon light on, I understand it's limitations

What is you thought , I plan to check for burned wires , anything visual like the VSS sensor and others. I'll have a look I think and see what transmission it has by Vin and door label .

Any suggestions ???

Thank you Iam50fast
