An update with an outcome. Went through all the tests very carefully again and again with no luck so went back to basics. Checked output speed sensor which showed correct ohms resistance but while I was cleaning the trans sump I had left meter connected and after about a minute it went to open circuit.
So it seems that the sensor can give correct reading initially but will show faulty after extended load test.
Replaced sensor now all gears have returned
What a pain to find but a brilliant find none the less.......so much better than the torque converter PO722
Thanks again to all for the input
