Auto transmission

[daddyduck]

Hi to all. I have a 2001 au11 Fairmont with 80,516km on the clock now when cold it makes a thud from 1st to 2nd. It settles down once the tranny has warmed up but may do it sometimes in traffic at low speeds. I blew $250 on a service which did nothing for the problem so now I take off slow and wait for the car to go into second then accelerate. So is my transmission problem a common problem in AU's.
