Are you sure the converter has engaged fully in the trans including the pump? Rotate when installing and two distinct engagements as it went in able to be felt - the shaft splines and then the pump drives? How much trans fluid went in?

So either a relief valve is stuck open (best problem to have) or pump is not working, possibly all the oil drained out of it and hasnít primed up. (Worst problem to have) If it has ran dry for a while it will probably be buggered.
Not sure about this but do the petrol and diesels run different converters, maybe in length? Converter is pulled to far forward and is not driving the pump now. I remember reading about different bell housings and input shafts somewhere on here.
From what I've understood thus far, there is a difference in stall of the torque converters, but I haven't researched if the two are physically different. Yes, the 4M engine has a different bell housing than the gasoline versions.

Iím sure the petrol and diesel have different bellhousings, one is about 10-15mm shorter (I think the petrol one due to the shorter motor).

They are also different in shape. My curiosity is now whether the input shaft of the petrol version is different from the diesel version. I've installed a petrol version gearbox in my diesel Pajero. If the shaft is shorter, It could have moved the torque converter far enough forward that the hydro pump isn't working.

It looks like I will be be tearing it apart again if so.

When you bolted the torque converter to the flex plate did it have to move forward a fair bit? From memory when I had the auto out of my NM it was about 5mm back and the standard bolts were long enough to thread in and pull it forward. Once again from memory the pump drive is 15 to 20mm long, so if the drive has pulled out you would have had to get longer bolts to pull the converter forward to bolt it up or would have had to lever it forward probably 20 to 25mm.
