I think that there was a version of the 700R4/4L60E/4L65E that was used in BMWs. It may have a removable 'bell housing' also. It is probably electronically controlled. I want to say someone sells an aftermarket controller. The physical size of the trans. may be a problem. Those guys over at pirate4x4 have probably built a margarita mixer from a 700r4 by now, ask them.
