I don't know how to upshift on downhill

Post by kayubassist »

From my house to the street,

slight uphill driveway -> stop/wait for the gate to open -> slowly approach the street (uphill) -> stop, look both left and right, slowly turn left into the street (uphill) -> start accelerating (downhill)

when accelerating, the street is downhill and I am having trouble upshifting at this stage.
as soon as I am on the street I shift to second and if I just leave the car in second, the car is too slow. I need to upshift to 3rd.
However, when I push clutch in, the rpms drops so fast, by the time I shift to 3rd and let the clutch out, the rpm need goes up instead of down. and this results in an unpleasant jerking motion.

How do I smoothly shift from 2nd to 3rd? Stepping on the throttle with the clutch in is the proper way? for upshifting?

Yes. Step on the accelerator a little bit to help your engine speed better match the speed that the transmission wants it to go.

In older cars you have to do it for almost every shift.

this, I have to do it almost everytime when I am taking my time..sometimes I can just drop the clutch and I manage to get it somewhat close to where it needs to be.

a few more options

-shift faster. double clutch if you necessary to synch up the gears.

-skip 2nd, wait a little longer than you would shifting out of 1st

-skip 3rd, assuming 4th is not too fast

I figured it out... kinda.
The rpm drops really fast only when the car is cold.
to minimize roughness and jerking, i shift to 2nd as soon as possible, and blip the throttle when shifting to 3rd.
on flat ground, i wait till the engine rev up little higher than usual so I have enough time to complete my shift before rpm drops below the 'ideal' range.

thanks guys for your help!
