Not entirely familiar with the auto's in these as I haven't had to work on mine yet, but based on other auto's I have worked on.....

Did you re-check fluid after a run? If it is like the other auto's I have worked on when you have drained it to change filter etc it will empty some of the torque converter/valve body and this only fully fills after a run. Refering to OP did it move at all after the filter change - if not, start up and move selector back and forth between D and R to push the fuid through the system and then re-check level.

Failing that, sure you didn't get any dirt/rag/cloth contamination in the valve body when you had the sump off? Something blocking a valve in the valve body?

Checked the gear selector linkage to make sure it is moving freely - look under the van while someone else is moving it.

Otherwise I am thinking clutch/brake bands which is an auto specialist job......

Cheers,

Just a stab in the dark - a mate of mine had an Austin 1100 auto years ago and could only get reverse; turned out to be the selector lever cable had gone t!ts up somehow. Here endeth my technical know how
