700R4 - essential to buy a newer case?
It's time to rebuild my 700R4 (see sig below). I can afford a few weeks downtime this fall/early winter and decided to park the truck, pull the tranny and rebuild it.
I know the later 700R4's are "better" than the early ones and can be built stronger. My truck is used mostly as a daily driver to/from work and only occasionally to pull a trailer (usually a 16ft trihull boat or a trailer of contruction materials). There's no towing a 7,000lb camper through the mountains or anything like that.
Am I okay to rebuild my current tranny or would I be far better off finding a newer core? I've been searching junkyards and online but haven't found anything reasonable yet.
