Updating early 904 - is this a suitable donor?

Thanks for the info - I see the difference in the sun gear - didn't pay much attention when taking it apart so I'll check and see which I have.

Also good to know about th e mfg date - I figued it had to be '76 or '77 based on the chronological order of the list - nice to know for sure.

I'm also thinking about a reprogram kit (transgo) - this is a very mild street car so I don't want banging shifts. From the articles I've read the mildest stage just improves some overlap issues and removes some of the cushioning. Anybody have day to day experience with the kits? I'm going thru this with my dad - who was a chrsler dealer mechanic in the 60's...he's pretty skeptical of these kits.

Thanks again -
