2001 330ci transmission has coolant in it i need help!!

What is your question?

ok, i have a broken transmission oil cooler, which in turn leaked trans fluid out of the car, some on the ground,the rest inside the coolant tank and vice versa with the coolant(yes! coolant got into the transmission). I can drive the car but with a little slippage. after i realized that the trans fluid was the brown stuff on the ground i haven't driven it. i took it to a shop and they told me what i already knew! I've seen a few posts on the site but noone has posted any info after they changed the fluid and filter! HELP!!!!!
