I have a 2004 F-250 5.4 with 181,000. Just purchased from a utility company. Great shape. Drives like new.
Sometimes when the transmission shifts into O/D, I hear/feel a little grind or flutter sound. Seems like it is forward of the transmission, maybe in the torque converter area.
I can avoid this sound if I let off a little on the accelerator and let it "ease" into O/D. The grind/flutter occurs on a normal acceleration. Have not tried foot to the floor.
I can get the grind/flutter by disengaging and re-engaging the O/D
I just purchased this truck and it has 181,000 miles on it. The town I got it from says they serviced it regularly, but I have not been able to determine if the service included the transmission.
I have read in this forum the pros and cons of changing the fluid and filter in a high mileage transmission, and to be honest, just not sure which way to go.
I will look at the link you have provided. What are your thoughts on fluid changes in a high mileage transmission?
There is never a 'con' about changing the transmission fluid and filter. Would you not change the oil and filter in a high mileage engine? They are both oils and serve the same purpose. I have almost 234,000 miles on my truck and changed the transmission fluid and filters last week. She drives like new because she is maintained.

CHANGE IT.

How often have you changed it? Was the 234K the first time?
Sometimes a transmission fails right after a fluid change. There is a reason for this.
Often, a transmission is neglected until something goes wrong, like what you're seeing. The fluid is changed, hoping that will fix the problem. The real problem is that the trans is worn out, maybe due to the lack of fluid changes. New fluid doesn't fix the broken parts and it fails. It would also have failed if the fluid wasn't changed.
You may get lucky and new fluid takes care of your problem. Or the trans may be too far gone and it will fail.

The fluid looks decent and does not have a burnt smell. Other than this intermittent shudder issue, the transmission operates fine. I am trying to talk to the maintenance department where I got it. They said they had records.
I change my transmission fluid and filters once a year because I commute 100 miles a day. That's probably why I hold on to vehicles for 275,000+ miles, because they run reliably. Many people ignore the service intervals in their owners manual because they think it's unnecessary, or maybe they're just careless.
