Leak from 722.6 gearbox

[stargazerplus]

I have read some posts about transmission fluid leaking into the wiring loom on the post 1996 electronic boxes (and if not corrected, destroying an ecu). I seem to recall there is a modified part to prevent this happening. I just would like to do some preventative troubleshooting!

My question is:

Is there any checks on the car that I can make to see if this is a problem and where exactly do I look?

Many thanks in advance!
