Hi and welcome.
Bit more info to help us help you please?
What year is vehicle? TD4 or V6.
Which gears slip? All or just a specific gear or 2?
What mileage has box done?
Any recent maintenance done?
Was problem there before fluid change?
I had a slipping gear 4 on a 2001 model year and found a manufacturing problem. Not too hard to solve but it depends what yours is doing.

It's unlikely that a mega flush will work, those are just snake oil.
If all gears are slipping, it's possibly a pump issue, where the pump isn't generating enough pressure to hold the clutch pack locked.
It needs to go to an auto transmission specialist to have the fluid pressure checked when cold and hot.
Also a read of the gearbox TCM for codes and live data could be helpful.

Agree, all gears slipping is probably a common cause like the pump. That's why I asked for more info. Problem is, the more you use it and the more it slips, the more the clutches wear out !! At 125k miles it may be worth a recon box, but try to get the fault identified first. Pressure readings can be done on diagnostics I think.
And there was me going to chime in with "If guns don't kill people, rappers do - gears don't slip, clutches do!" - now I'm going to have to read the rest of this thread and figure out some technically constructive to contribute with.
Might be worth making sure who ever does the fluid level change sees this video on how to check the level...
...reason I dug this out is there's a bolt at the back that often gets mistaken for a filler plug, that when undone to fill it with fluid, causes the reverse clutch band to drop out permanently crippling that gear, or until the box is rebuilt.

Same gearbox to best of knowledge.

Surely worth checking that the fluid level is correct before changing the box?
I have a spare 80 k miles autobox but you are a bit far away !!

Is reverse effected by slipping too?

So was the "gearbox" slipping and revs red lining, or were there no revs?
During these instances of slipping, do the revs rise, or is the engine not reving?
