Of course I ripped that off from the web, it's not my idea. And someone else retaliated, at some point.

I made a version of that a while back...

A torque converter does something that a clutch simply can't and that's multiply torque.

The NHRA Pro Stock cars will always have a special place with me though.

I think I saw that version too--I had come across the first one and wanted to find a better version to post, saw a few variants.

All fun and games of course.

Nice video, Ronnie Sox was called Mr shifter back in the day. It will be a sad day indeed when pro stock goes to automatics!

Whether I prefer manual or auto depends on the vehicle application. There are some really dreadful autos that are programmed for fuel economy, and there are some that are far superior to manual. The ZF 8-speed with proper programming is a great transmission. Then you have the manuals with rubber band shift feel or gear lock-outs to meet CAFE. duh

How does a Dual Clutch automatic transmission work?

Probably like the regular automatic, but 2 seconds faster in the end!

The ZF in my Ram is the first automatic I've ever had that I couldn't shift any better than myself.. its a great transmission.

LOL Those are all great!

With all the newfangled transmissions nowadays, some racing seems like more of a science than a driving skill test.

Loved the cigar in that video! Also like the elbow flying up in preparation for each shift.

If my vehicle came with a manual, that's what I would be driving…

My dad made a career of designing automatic transmissions for the automotive industry. They were once tasked to build transmissions for racing. He said they could not design something to outperform existing manual transmissions and the drivers who use them. I'm sure weight, power loss, and shifting protocols were considered were parts of the variables.

Conversely, he chuckled anytime somebody tried to drive an automatic like a manual. The automatic picks the best shift points. Just leave it in Drive and go!

Back in the day that WAS funny.

However with modern automatics set at the factory in many cases just for mpg, the "best" shift point - which is different between vehicles, their drivers, and how they are used - isn't available without a tune. Same goes for throttle response.
