While transmission gearing can be a little bit preferential, I found just the 4 speeds in my old '89 GM 700-R4 to be more than adequate when mated behind a decently powerful, torquey engine. I did some serious 4-wheeling and towing with that setup, and it did just fine. The tranny has a low 1st and well spaced gearing up to the 4th which was an overdrive. While the gearing performed well, that model of tranny needed some good mods to make it work well and live long, and I had those done to mine.

I know that closer spacing with more gears maintains keeping the engine in its rpm-to-power sweet spot. On a truck with a decently wide torque and power band, is this as critical? Now we're talking about 8 speeds and such, and while I agree there's benefit, is perhaps some of this being driven by marketing hoopla a bit? And I realize why semi's have many gear selections to optimize their hauling capacity and economy, but that may be a stretch of a comparison for a 1/2 ton pickup. Still, I know there's some application even then. I'm thinking sometimes that 4 or 5 gears max, designed in a more robust and stouter package would be better than 8 gears in a package where they're trying to cut weight and increase fuel economy...at least on a pickup. All the money saved in fuel economy can quickly evaporate when you get the $1500-$3000 repair bill on your whizbang 12-speed auto...LOL!

And please don't take my comments as argumentative on this issue. I just wonder sometimes...are we overdoing it? And don't get me wrong. I love more, more, and even some more when it comes to power, bells-and-whistles, and hoopla as much as anyone...LOL!

One other question, because I'm new to Dodge. I'm sure I could research this one, but the comment made here about this tranny being based on a 40 year old design...if that's true, does this mean this tranny is just a redesigned Torqueflite?
