THE TRANSMISSION SLIPS UNTIL ABOUT 40MPH THEN

2000 BMW 540

Transmission problem
2000 BMW 540 V8 Two Wheel Drive Automatic 106000 miles

The abs control module which was rebuilt by module masters, dsc pressure valve, and front wheel sensor were all replaced, The Dash Abs lights all are now out, but the tranny still slips. The dealer said gear 1, 2, 3 shows faults. The dealer says they do not fix, the only replace. What should I do. Dealer said the fluid was fine, could this be the bands or clutch plates? Are the gears bad? Please help? What is a reasonable cost for Z F 5 speed transmission? Thank you for your help! Could this be a simple as a vacum leak?
