i would like to rebuild my transmission myself may be of some help. I looked into doing my transmission and found the investment in tools was more than I was willing to spend. I did go as far as tearing down a transmission using a vertical band saw in place of some special tools it is an amazing piece of equipment one member of this board did rebuild his transmission successfully I will try to find the thread it was some time ago here is a link to a company that you can purchase the parts from http://www.europeantransmissions.com/europeanhomepage.html
There is also a company in San Jose that sells rebuilds kits and technical information I don’t recall there name but my son should I will ask him when he gets home.
