Automatic gearbox codes for a bora

[AUC-05L]

Hi all.

I have recently picked up a tidy 2002 v5 bora auto. The previous owner said the gearbox isn't shifting properly, holding gear etc. He was going to replace the box. I'm considering fixing it as another box is hard to find. What would the gearbox code be?

Any help would be greatly appreciated.
