4T40E - no rear gear and on neutral...

[samuel_sss]

I have repaired my 4T40-E. I have change the shaft oil pump drive, the sleeve output stub shaft, the ring otput stub shaft, the convertor, the housing A pump, I put 12 quarts(11.5 liters) of liquid But now the car does not have rear gear and on neutral position it makes attempts to move forward a little bit.
What could be the problem- is there any secret for filling the liquid?
Thank you in advance,
Sam
