Best case scenario for DTC P0741

[Jennifer Fradella]

Hey Jen, hope you are well. Your issue may have been resolved by the fluid change. Some time and driving needed to done in order for the fluid to do it's job. It sounds like the solenoid was sticking and flushing the fluid with new clean and proper fluid may have resolved the issue. There was an issue with the late 90's,early2000's crown vics and grand marquis where the transmission would shudder when the torque converter locked up. Fords first repair was to flush the fluid out and replace with new. The customer was then instructed to drive at least 5000 kms for the repair to be confirmed. I'd say about 90% of the vehicles were repaired with just that. Just as an afterthought,i know to the layperson,a flashing light on the dash can be nerve wracking. Rest assured that the p0741 is not detrimental to the operation of the transmission,and won't cause damage. It's a fluid pressure fed lock up mechanism inside the torque converter that's not locking up. Worst case scenario is you're not getting the best gas mileage that you could. Hope this helps a little and certainly hope that your issue is resolved. Take care.R.

Thank you for your help. I’m takin it out of town on Sunday and hoping it doesn’t come up again. It’s been fine the whole week, just don’t want to speak too soon. Hope you’re right

Hey guys,like i said before,it might be worth your while to ask at a ford dealer,or a very reputable transmission shop that has the tester for the solenoids. JExpedition07,what you're describing with bump shift coming to a stop is exactly what i had and a software update cured it. It's an easy thing for me to say cause i have a friend that is a tech at a ford dealer who told me about it. I believe it was a service bulletin for our vintage of expy's.

Just spoke to my transmission shop, and because of the symptoms, he recommended taking it in for a reflash under TSB-09-15-8. He said it was specific to the 09 Expedition. I am about to call.

Does anyone know about reflashing the transmission, etc, the cost, and if that was effective?

I actually haven’t had that downshift clunk in a while, seemed to subside.

We had an '09 Limited that would didn't throw any trans related codes, but would hard down shift into 4th. I drive a lot between Seattle and Sacramento, so this was especially bad coming through the pass into California. We had the trans re-flashed under the TSB, and the problem lessened.


I'm of the opinion that when a TSB exists for a software update, it's usually worth doing.

Most TSB's in general are worth doing

When I worked at a L/M dealer, when it got slow we would search all the vehicles in the lot for outstanding TSB's and do them to keep us working

What was the cost of the update? They said they charge $110 so they can diagnose “themselves” then would put the $110 toward the fix.

I have no idea

We did TSB's as warranty work on vehicles in the lot if that's what you are asking and this was back in the mid '80s timeframe

I am not talking about this specific update I am talking about TSB's in general

Ok so I took it in for the reflash 3 weeks ago. Since that time, I have had the same code, and now a new one. Calling ford tomorrow bec I feel like they may not have programmed it correctly? Can someone tell me what this now means please?

P260f, P0100, & P0101 are the newest codes


P0741 is why I sent it there for the TSB


Oh, and I also feel like I hear some kind of buzzing sound upon start up, or at a stop, sometimes now. Don’t remember hearing that before sending it in.

Hello Miss Jennifer. Hope you are well. It's been a year since seeing a post on your issue. What was the outcome? Did the reflash help?
