Down Shift W/O the Clutch!

ChrisSlicks · 05-11-2010, 07:30 PM

I commonly double clutch 1st and sometimes 2nd gear, especially while the transmission fluid is cold. The syncro's in these 2 gears aren't the best.

OP does make sense. Although its an interesting find, i find no application for the technique. How is it on the tranny?

The application for this technique is shifting with a blown clutch.

If your going to drop $40 k on a sports car, make sure your not too poor afterwards to beable to afford towing your car and getting the clutch replaced, and/or dont buy your 17 year old child a $40 k sports car who's going to drive like a jag off and blow a clutch.

just my .2 cents

Meh... what if you're in the middle of nowhere or if you're a mile from your house? It's really not that big of a deal.

Or if your syncros are gone and you want to keep your gears from grinding while operating the car.

That's where double clutching would come in.

chuckd05 · 05-11-2010, 07:49 PM

This will keep you going without a clutch...... until you come to a stop . wtf?

A friend of mine drove homew with this for a clutch a few years ago:

Start the car in gear...

That's the clutch out of a 2001 Mustang Cobra, BTW.

Just quote Toretto and get it over with. Maybe you'll be the 10,000,000th person to do so.

Try this.

1. from 5th gear push the clutch in.(or just pul the gear lever w/o the clutch)
2. next move the gear lever into neutral.
3. let the clutch out.
4. now without depressing the clutch push the gear lever to 4th gear.
5. Viola! The syncro-rev blips the throttle and the lever falls into 4th without needing to clutch in!

is this your first MT car?

wat a useless technique. double clutching is good when you need to get into first from 2nd while still moving forward and your syncro locks you out...or after you stop to get into reverse.

i thought you were downshifting without the use of your clutch... now that i would've been interested in reading how you had to get a new tranny.

You are correct. Double clutching is pointless nowadays. Clutch less shifting is good to know how to do. OP must needs to get his facts straight before he starts telling people to research what he himself doesn't know.

AK please lock this thread
