Manual vs. Auto Transmission

**Psst** Auto has 4 gears... *blends back into the walls **

1. It was only my foot, not my leg. Actually, only part of my foot. The ball of my foot.
2. I wouldn't be driving a V8 to begin with, let alone a manual V8. At best, a V6 is what I'd ever own.
3. Thanks for your input though!

(P.S. It's mostly a matter of how I have my foot positioned on the clutch more than the clutch itself).

Yeah, the auto is a 4 speed. Toyota does need to change that though. Ford will have 6 speeds in the Fiesta and Focus giving Ford a big edge. Hopefully the next Yaris and Corolla with have the same but something tells me they won't (at least Yaris probably won't).

D'OH! i knew that. i meant the auto final gear is higher than the manual's 5th gear.

But being that it has 1 extra gear and the gears are shorter, it has a GREAT DEAL more power. Furthermore, MT always put more power to the wheel than autos, with the exception of expensive DSG/SMG/hydraulic auto-manuals. Those are tried and true manual transmissions that are electronically controlled. However an automatic with a selector/paddles and a regular torque converter and planetary gearset auto is NOT the same. Not all auto trannies are equal.

Higher final drive=taller final gearing=equals lower top gear RPMs, which in theory its highway mileage should be better.

You still got it wrong. Somehow you're associating higher gearing with higher RPMs. It's just the opposite. Higher gearing = lower RPMs.

no, i said the auto has a higher final gear (thus lower rpm's).

the people saying the mt has higher final gearing are wrong. if you drive an automatic yaris and a manual tranny yaris at 70 mph, i assure you that the automatic is running at lower rpm's. this has been confirmed plenty of times.

Oops. . . I meant lower final drive. I always swap high/low. If you read to the rest of my post, it is consistent with the error.

That was in my original post. Let me just rephrase and say that the MT has a SHORTER final drive.

With forty years of driving I have lost my taste for manual transmissions. I have become lazy.

Went for the manual, never regretted it. I live in the mountains so the shorter top gear means climbing hills in 5th where with the auto it'd need to kickdown into 3rd or maybe even 2nd. In traffic I find it easier to shift into neutral whether I'm driving stick or auto, so it really makes no difference.

Plus, if the accelerator sticks I can clutch as I brake, leaving both hands free for the steering. Or the Rosary.

You've got it right then.

manual makes you think ahead for what waits further up the road . Helps to keep you more alert ( or awake ) .

I wanted a manual, but got an AT. After reading about the DBW TB and how some people have difficulty adjusting to the DBW, I'm happy with my AT. Br careful what you wish for.
