I have a copy of the Dodge service manual on CD for the 70 Challenger. I'm happy to print and scan the pages associated with pulling the transmission so they can be posted to a reply as an attachment. If you want all of the details with all of the exploded drawings of the inside of the A-833 and the associated text about a rebuild, it's probably better if I print all of those pages and mail them to you. If you want the details, PM me your snail mail address and I'll get them on their way to you. If you want the short version, I will post them later tonight. Your choice.
