there is a solinoid that is prone to bite the bullet in falcon auto boxes.i forget what its called,sorry,but it controls 1st to 2nd gearchanges and when it blows it causes harsh changes between those gears.
get a diagnostic check done at a gearbox place.

cheers

Yes ...You'd like to think that because its just been serviced they'd have fixed that ??....
Btw they don't empty ALL the ATF out...Some ATF stays in converter...They need to flush system..Which that may have done...

I have a AU2 XR8 Ute this thing also has the same drama with hard down change I took it too Jarvis Ford to get it rectified 3 times none of their technicians could find a fault Trans service and flush helped a little but not enough.
Any ideas how much to get the solenoid fixed

I remember reading a long long time ago on FordForums about this issue. However, these posts are long gone now.

I remember reading about a design fault in the AU XR8 boxes, and the rectification was a different type of valve body.
