Auto pulls harder than Manual with same gear ratio

[dude]

I found this on a post in a different forum, which I thought was quite informative, especially how autos pull harder than a manual with the same gear ratio. Your thoughts? I would think this might apply to this generation's transmissions, since they carry over the same ones (MT82 and 6R80) with some changes.

Perhaps this is why there is no Performance Pack for the GT Auto?

Also, which transmission are you optioning in?
Are you staying with a manual? (MT82)
Or are you optioning in the automatic? (6R80)

The reason why this is significant is because the gear ratios in each gear box are significantly different.
The automatic (6R80) has a much deeper 1st gear, so off the line, with 3.73:1 rear gears, it is like the manual (MT82) with a 4.10:1 rear gear (4.10:1 is not even available as a factory option).
So deep is the automatic's 1st gear that it comes factory stock with 3.15:1 rear gears with 3.31:1 and 3.55:1 as options (I do not know if the 3.73:1 is an option for the automatic).

In direct comparison: a GT with automatic with 3.31:1 rear gear will feel like it pulls significantly harder than the manual with 3.31:1.

So, whenever you go test driving, dont just try manuals with 3.31:1, & 3.73:1 gears, also test drive automatics with 3.31:1 and 3.55:1 gears and see which car pulls harder.

Aside from the rear gears, rumor has it that the automatic 6R80 is designed to take a flywheel torque load of 800ft-lbf. I do not know if this is true because I have not seen any Ford publication that states this.
And actually, Ford does not even publish the MT82's 380ft-lbf flywheel rating either. And nor does Getrag, the sub-contractor that makes the MT82 for Ford. I only know this because Ford engineers who designed the Ford Coyote 5.0 engine said this in an interview with a car magazine. And it makes sense that the Coyote 5.0 with 390ft-lbf flywheel torque rating does not grossly exceed the MT82 380ft-lbf rating. Heck, even the Roadrunner (Boss 302 engine) had its peak torque reduced to 380ft-lbf to match the MT82's rating.

The MT-82 torque rating is wrong, and posted wrong again for the millionth time. 369ft-lbs of torque @3xxx KG( or damn near 10,000lbs) GVRW. Let's try to stop circulating that BS that it's rated for less torque than the engine puts out please.

The subjective 'pulls harder' isn't really enough for me to base any decision off of in my opinion. Put some objective info if you really want a decent discussion.

Not the same gear ratios; just similar final drives in some instances.

This would only be true for the 5.0L. The manual ratios for the V6 and EB are shorter than the auto.

Thank you grimace, I was just going to post that again as the op is just spreading ignorance.

This. As the cars weight drops below 10,000 lbs, the torque rating handling ability goes up drastically.
