!Jerky shifting concerns!

[celenium]

I've been driviing for over a year now mostly self taught shifting.
I've noticed that my shifting is jerky. It's gotten jerkier when i first learned to shift.I have a fear of wearing out the clutch so I try to release the clutch as much as possible before pressing the gas pedal.

Especially if I go into vvtli, the car is pretty jerky.
The question i had was whether this type of driving is puts more wear on the transmission or not?

The way it sounds like youre shifting will elongate the life of the clutch disk, but will shorten the life of the throw-out bearing..Might as well just slip the clutch and have normal wear on both parts..

Where are you shifting at rpm wise? There is a natural rpm to shift where you can do it smoothly w/o going into lift. A nice gradual acceleration. It doesn't happen all the time. You shouldn't lean forward wanting to faster, but you shouldn't be pushed back... it's around 4-4.5K...

Letting the clutch out securely is important, but your car should not be surging, or jerking excessively when shifting. Ideally your car should not jerk when shifting. It's ok to let out the clutch slowly... just don't ride it.

Clutch engagement on the Celica is almost immediate vs. the Honda I had, and the Subara 2.5 RS I've driven. Which may explain jerkier behavior if you learned on a diff car.

"Especially if I go into vvtli, the car is pretty jerky."
You are probably having the same issue I have. You gun it... up to redline, shift, and get a major jolt. 95% chance is you didn't land in 6K range either. The ideal acceleration is to never go forward when shifting. It IS possible, but can be hard to nail 100% of the time. Try this: WOT in 1st, clutch in, shift to 2nd, Step on gas WOT, then let out clutch (not too harshly). If you nail it, you will never surge forward-the 6K will keep you planted in your seat.

If you are casually shifting (not all out gunning it) above 6K, there will be a significant difference since you are going from haul ass -> cruisin' range. (... I'm just rambling now so you can ignore me if you want). You can gun it all the way in 1st, and then go into 3rd, and the transition is smooth provided you're not hauling ass to get into 3rd. I do this if I am pulling out and need to get to speed quickly, but I don't need to make a new 1/4 mile record. Basically I just need to get to 40mph quick. Gunning in first and then lazy 2nd shift would be upsetting. Gunning in first then 3rd (no more WOT) is ok. I also skip gears when getting on Highway. Goin' WOT thru 3rd, hit 70ish, then go into 5th or 6th.

"The question i had was whether this type of driving is puts more wear on the transmission or not?"

And so... I finally answer your question (provided anyone has made it this far)... it depends on how harsh you let out your clutch. Any jolting of your car is not a good thing. Everything should be kept smooth, except having your ass thrown back in your seat in lift :)

ok here's the thing though.
When u redline our car, you want to go fast so don't most people dump the clutch quickly when shifting? If you dont relase the clutch fast enough, then the acceleration won't engage as fast.

If you don't engage as quickly, you lose rpms. On the Celi GTS 6sp. It is mathematically impossible to PROPERLY shift and stay in 6K from 1st to 2nd. The only way to stay in lift is to essentially get on the gas a split second before you engage the clutch. Other cars don't have this big of an issue. I've had my car for 5 months and it's taken me a while to feel comfortable w/ full on acceleration, and nailing the shift. Knowing that it was impossible to land 6K by PROPERLY shifting helped.

The important part is to shift swiftly and securely. If you don't get on the gas soon enough, you may bog down and whip forward. Getting on the gas quickly is as important as letting out the clutch quickly. It can be a fine line and will take some practice.

If you hear your clutch slip (like when newbies are afraid of stalling so they rev up, and let out the clutch real slow) then you need to let clutch out sooner or quicker.

how do you hear it slip?
How can u tell ?
