Hey guys,

I would like to do the low gear swap on my 72 year 904 transmission. My transmission currently has aluminum 4 pinion planets front and rear.

My first question- what vehicles have low gear set transmissions? My local wreckers is scarce for 80's year chryslers, so later model stuff like dakota trucks, 6cyl jeeps, late model rams, etc. is all I really have to pick from. What year vehicles would have the transmissions I am looking for?

Second- when I get the transmission apart, what parts am I looking for from it? I have read that the planetaries are steel in these transmissions- can I swap both in to my current 72 year aluminum planet trans? Are there any other mods to get the low gear set to work?

Thanks!
