Help with TH400 gearbox

Hi - my gearbox is making a hissing sound under acceleration when changing from 1st to second gear. The sound is similar to a smallish very high pressure water jet and lasts a second or so then the box changes normally - it seems to go away once the box is hot. Have noticed that the changes are ever so slightly softer but that might be my imagination.

Anybody know what the problem could be?
