Double Clutch Hmmm?
Topic 16577 | Page 2
I did my introductory road test at Swift here in So Cal in a manual and did not have to DC.

The problem with all this advice is that David learned to drive with a synchronized transmission, therefore he doesn't know how to double clutch or float the gears. He's got to do one or the othet on his road test. He will never get through it if he tries to operate the clutch like he did in that six speed. He's going to be grinding gears terribly and may posdibly not even be able to get it to shift at all.
Float The Gears:
An expression used to describe someone who is shifting gears without using the clutch at all. Drivers are taught to "Double Clutch" or press and release the clutch twice for each gear shift. If you're floating gears it means you're simply shifting without using the clutch at all.
Double Clutch:
To engage and then disengage the clutch twice for every gear change.
When double clutching you will push in the clutch, take the gearshift out of gear, release the clutch, press the clutch in again, shift the gearshift into the next gear, then release the clutch.
This is done on standard transmissions which do not have synchronizers in them, like those found in almost all Class A trucks.

...not to mention managing low vs. high range. He is going to have his hands full...and likely hasn't realized it yet.

David what you learned on is likely a synchronized transmission and can be straight-sticked like a car. Very different than what Swift will test you in. You should take a look at this You Tube video on shifting an 8 speed. You have some "learning" to do before you take the road test. Once you reviewed this come back and we can advise accordingly...
Ok G-Town, will get right on it. Thanks.
David...if I were you I'd rent either an 8-speed or 10-speed to practice. This is going to be like nothing you have ever experienced.
Even people that catch on to up shifting really quick have to practice down shifting.
You need to gain access to a truck and practice. You can't wing it. It's un-wingable, lol.
Un-wingable. This should be added to the glossary.
