Hi Karen,
The red/pink fluid is A.T.F. Auto Transmission Fluid.
It's purpose is to lubricate the gearbox, if only a small amount has leaked out you're probably ok to drive to your local garage and have it repaired. If all the A.T.F. Leaks out and you drive the vehicle , the gearbox will be seriously damaged.
