Yes.
LOL! You can be a real wanker sometimes George. :p

We call it "power shifting" around here..

Yep! thats what they are!

I've never even heard of someone calling them "clearance" lights until I saw it here on this forum. :D

What the hell is a clearance light? :huh:

Is that the blue spinnig light they used to have at Walmart?

hahehah,..you guys are real funny....:silly2:

Did I answer the question? :)

When there is a more specific question, I'll answer. :sun:

Please explain how to do a "clutchless" shift. Is that specific enough for you? :flipa:

Well.... If you want to flip me off......

Match revs. :finger:

b-b00gie,

I am going by the book :) I don't think there is anywhere in the user manual once mentioned the word "parking light". They used the "clearance light" instead. Unless the US user manual printed differently.....And yes I did read the user manual :D

this knowledge is quite wise when you got a crippled left foot!!! :p

Or when your clutch cable breaks across town and you are just starting out on a night of fun. Happened to me 21.5 years ago. You must match revs precisely, up and down.

When you get it right, it just slips into gear w/o a complaint. When you get it wrong....... :eek:

Sucks that this happened to you but look it in the bright side that you managed to drive the car and didn't call for help otherwise others might have done so.

It's amazing that the G20 has this capability. This might be impossible to other cars in its class.

Match revs is the key to prolonging clutch and brake discs.....if you downshift well, you dont' have to use brake at all.

I dont think he was talking about his G20.... unless they had them 21.5 years ago! heh...



But it can be done in any car as long as you are good enough. ;)

Don't use engine braking. Brakes are cheaper than a clutch an gearbox to fix.

That's also a good point :licker:

Following you guys but still dont understand "matching revs" you mean accelarate to about 5500 shift again to 5500?:rolleyes:

It's about right, but let's be more specific.

Okay, let's take a scenario...
You are driving on 3rd gear at 55 kph (~25 mph) at 3500 rpm. To change to 4rd gear without using clutch, you need to rev up your rpm to about, say 4000 rpm, to accelerate a bit, then release throttle and at the same time firmly but diligently pull back the shift knob and push it into 4th gear. If done right, the rpm should now at approx. 3100 to 3250 due to 4th gear loading. If you are doing too slow, the rpm would now fall to, say 2500 rpm, which is a significant drop for a gear change from 3rd (4000 rpm) to 4th (2500), so by matching revs, we mean you need to match the 2500 rpm to about 3100 to 3250. NOTE: This is instantenous time. All this is done on the assumption that the change in speed at which you were going is very minimal. In the case when the speed is dropped significantly, you need to rev up then shift to 2nd gear, accelerates then try again but this time shifting to 3rd gear. If everything is done right, it should snaps in place. If not...OUCH!!!

I am better at "power" downshift than upshift.
Hope this helps but don't blame me if things do go wrong. It takes time and practices to make things perfect.

Ok Cool i'll go rent a car and try it out HA HA this way i wont mess up my car!:finger:

Thought I'd better mention this important point.

The shifting is done in 2 distinct parts. First part, unload the drivetrain by feathering the throttle so that the car is coasting or very slightly decelerating, not accelerating. Then shift out of gear and into neutral.

Second part, match engine revs with vehicle speed for the gear you are going to shift into, then shift. Engage the gear but do not use excessice force.

In doing all of this you need to satify two parameters.

1) During shifting the drivetrain is under light to no load

2) Sychronisation of engine revs and vehicle speed for the gear to be selected.

well, thought out T4.......

I can do it with an Auto! I start in 1st and give it some juice. And when I should be shiffting to 2nd, I throw it in 2nd and right as the tranny is shiffting to 2nd I throw it back to 1st and it acts like it is in 2nd gear and you get more pick-up. After I almost get to redline, I throw it past 2nd gear>>>>>to the Drive gear. Somebody told me this is the way to race Auto's. Anyone ever heard of this?
