OOOH, WOW! an 8 speed automatic!
Oh, wait, didn't GM make an 8 speed automatic sometime in the 1950s, by putting a dual range in the old 4 speed Hydramatic and "beefing it up"? Didn't they intend on putting it in heavy duty trucks? And, wasn't it a failure because very few drivers wanted it?
Maybe now the heavy duty truck drivers are ready for a full-on automatic.
Of course, it could very well be that my memory is faulty. That happens a lot now that I am over 75!
