I have instruction of how to disassemble the 03 z4 tranny. I have rebuilt the tranny. Since I do not have all the necessary jigs, I have made temporary jigs and managed to assemble the tranny. However, binding problems are current. If anyone of you have assemble a z4 tranny, please forward me your phone number and I will contact you tomorrow. If you are helpful, I will paypal you $200.
