The $75 price tag for the puller kinda has me in shock. I'm probably gonna run the whole trannie over to the BMW (Ironhorse in Tucson) and have them pull the output flange. Or I'll fabricate something. One of the articles I read gives dimensions for cutting the flange plate and there is an Industrial Metal Supply shop here in town that could cut the plate out.
Same with the holder. I can cut steel and have a mig and a drill press.
It's all a little hard to picture until I can get into the trans, I'll read & study as I go along. I do have a Haynes and a BMW factory service manual as well.
Something to do on the kitchen table this winter, I think.
