sounds like the pump to me if you have no flow at all that is a big concern quite a few things can come into play there. i do have a book on these autos iv had a few issues from time to time mainly self inflicted tho
. was the gearbox a brand new one or a secondhand job? most important did you replace the torque converter ?

yeah torquy was new and the gear box was ment to be a reco job im personally think the pump shaft might be stuffed ?????

its hard to say without seeing the gearbox. it could even be one of the check balls in the input shaft it could be a broken spring inside the pump. i can supply info out of the book if you require it. iv found it helpfull at times like this. seeing as there is no pressure at all it all points back to the pump. this might be a long shot is the filter fitted correctly? possibly it has come adrift ? would be worth checking

Are your transmission cooler lines blocked? Is the raidiator oil cooler blocked?
I've seen that before...

This will also help. Yes the electronics will cause issues like this. Make sure u check the fuses as the tcm one might be blown.
