Can anyone enlighten me on this? I cant find any info anywhere.
It automatically changes from TARA to TA only when below +/- 1000 agl

What does "plus or minus 1000 above ground level" mean?

On the A320, the transponder mode selector has 3 positions, being:
STBY : Both ATC transponders are electrically supplied but do not operate.
ON : Selected transponder operates.
AUTO : In flight : Selected transponder operates.
AUTO : On ground : Selected transponder operates only in mode S (Selective aircraft interrogation mode).
Holpe this helps...

What does "plus or minus 1000 above ground level" mean? Well I guess it covers all eventualities!
Err
Approximately 1000 feet above the ground
