My TS down shifts quite hard when i floor it. Do you guys have any cheap and quick solution to this problem?

dont floor it;)

Check your autotrans fluid level.

my auto trans fluid is full n pink. what can be wrong?

your gearbox aint exactly new either.

have you checked your kick down adjustment?

i'm guessing it has a kick down adjustment and it is not done electronically.

When was the last time the trans had a proper service?

i had a transmission flush (hookup with machine to flush most of the old fluid) with filter change done on 31/12/2003. prior to that, i have had a service in early 2003 (a conventional transmission service).
