2g auto no forward gears

[68442]

Reverse is fine. Slowly started to get delay when putting car into drive. Once in drive etc hard shifts with the shift box so I assume that the clutches are good. Today it was fine one second then nothing. I read reverse shares 1st so leaning towards electric, could one of the plugs on the tranny have become loose? Won't be able to check till after work. Has been trouble free till this came up.

Update: After work when it was cold it went right into forward gears, drove home fine. Once home no forward gears again when I tried after parking. Must be a o-ring or gasket allowing the hot thin fluid to leak preventing kicking it into the forward gears??
