I get lazy sometimes and grind gears from not full pressing in clutch to shift.
My truck a 1988 Ranger 4x4 was no problem to shift with no clutch. I could upshift,downshift, and even go from neutral to first with just tapping the gas while moving.
Maybe the Yaris will start to like it after 200k.
I should add that I drive trucks for a living and only use clutch to start off. If I double clutch each shift I would be on my 3rd knee by now.
A lot of tractor trailers now have automatic transmission.
Probably not the best thing to do till it gets some miles on it

^^ good stuff haha. I've shifted 1-4 several times in my xB, without using the clutch, and have shown a few passengers it can be done. But the pop noise when you pull the shifter to get out of a gear, it does not sound good, for long term wear and tear. I would not recommend this for normal driving at all.

Blip the gas a tad before you bring it out.

djct_watt · 06-19-2010, 06:44 AM

^if you are doing it right there should be no pop sound. You need to shift to neutral at zero load; it's the moment you're neither applying
power nor engine braking.

You need to pull it out of gear at the same time you let off the gas. If not exact on timming you will force it out of gear.

I've done it several time and it always make the noise, maybe the xB is diff?

djct_watt · 06-19-2010, 07:15 AM

I've tried it on my yaris, and also on both my xA and tC without the noise. The xB1 shares the same tranny and engine as the yaris and the xA, and the xB2 shares
the same engine/tranny as the tC. So the xB is not different.

XB and Yaris trannys are different.

O. Maybe. The gearing is different. Thats all I was getting to.

According to these sites,
http://www.vibratesoftware.com/html_...ear_Ratios.htm
http://www.vehix.com/car-reviews/200...specifications
http://www.yarisworld.com/forums/showthread.php?t=4997

They are exactly the same. Maybe the sites are wrong? The only difference is the final drive (which is easily changed between transmissions). But the gear ratios are the same.

I've shifted without the clutch on previous cars....just to see how/that it could be done, but I gotta agree with everyone here, it just shouldn't really be done because the transmission has syncros and was designed to be shifted with a clutch, so it is most likely in the transmission's best interest to shift with the clutch.

I double clutch whenever making big downshifts, like for example if I'm going to put the car in 2nd gear at 40mph (for a fun turn) I'll put the car in neutral with the clutch out and blip it up to 4,000rpm real quick, and then it shift into 2nd gear, it's amazing the difference feeling it just "drop" into 2nd in this situation (no waiting for the syncros to work). I believe this (double clutching for big downshifts) is very good for the life of the syncros. Shifting without the clutch would do the opposite to the life of the syncros UNLESS you literally rev matched PERFECTLY every time. Which I don't care how good of a driver you are, the Yaris' electronic throttle and other environmental factors will not allow you to literally perfectly rev match every shift - You're going to be putting wear on the syncros, and it will be more wear than normal.
