I worked as a transmission rebuilder in a small shop for 10 years, before what I do now. To an experienced builder a 32RH is a walk in the park to get right and a sturdy little unit. They make simple upgrades to add cooler flow in Park also.
I do not mean to further ignite any Ford/Chevy/Dodge super transmission arguments. And I didn't mind rebuilding Ford transmissions, ford is one of the toughest domestics there is to rebuild, all around they have so many variants and split years and weird changes they streamline nothing. No, I am not referring to the C4/C6. And in the transmission industry, the AOD is not regarded as durable. Be as pissed as you like, I would place my bet on a 32RH would put up a better fight as far as durability than an AOD.
It's great your half ton ford hauls peanuts so well at 25MPH though, that's nice.
