Early this year we went to the Advance Auto Part meeting in Charlotte and the idea was to include our 2007 in the booth, so far so good. We stayed in a 1st class hotel right downtown, the 2007 G56 and my 2005 NV5600 made the trip. The only parking was indoors and valet, oh boy these kids are in for a treat. The launch point for the valet started UPHILL and 60' later hard right, repeat and repeat. I asked the clean cut valet if he knew how to drive a manual, Of course sir, we know how! OK, how about a full size Dodge with a Diesel engine and a manual, a bit of stuttering and stammering followed, oh by the way, I work for a clutch company etc, etc. The panic was starting to take over his expression. Then I told him that a 2nd truck our show display truck would be here soon and would need "kid glove" respect, he sorta gulped IIRC. I suggested that due to circumstances, I'd go along as co-pilot, Yes Sir, that would be fine with me. I tried to introduce the concept of torque at idle with the Cummins and no need to give it any "gas" to get it rolling. He just couldn't grasp the concept and it took a bit but we did make it, but when he finally accepted the engage 1st gear at IDLE, let it pull on its own well, can you say he was startled by the power at idle?
We wound up tutoring 3 valets about these powerful drivetrains and had no problems with respect for the trucks and their unique outfitting.
3 on the tree, owned two Fords and one was an Econoline pickup with the doghouse and real cab forward design. Don't remember how many miles were on that worn out 3 on the tree, but if you got sloppy sliding it into 2nd, the selector at the bottom of the column would get stuck between positions and it was ALL STOP, get out and pull it back into sync, not real hard, but this old Ford didn't have a parking brake that worked, truck in N, no brakes, ya'll be careful.
I have 3 kids and two of them are proficient with manuals, oldest daughter ran a Neon for years and son has a '97 3500 NV4500. I think they both appreciate the skill.
I really believe that the CAFE requirements were a major influence on clutches, in particular pushing the design of torsion dampers to tackle noise that used to be non-existant due to heavy parts and 85W140, flywheel and M/T designs and most likely pushed the trend to where we are today, disposable clutches as opposed to the old heavy rebuildable clutches that most of us grew up with.
