Shiftin' Question

there is if he grinds second for 30 seconds trying to get it in gear..let me put it this way..he bought the vette new..in the first year he had to have the trans rebuilt twice..bent shift forks busted gears...he couldn't drive a stick to save his life..why he bought a vette with a manual instead of an auto I will never know...

I can double clutch a cobalt SS or a vette or a pete or a camaro..its all the same process ..just different timing..I grew up bracket racing..its not hard to do at all.

Ever since I started trucking I double clutch my brothers Chevy silverado. Only thing I have a hard time with is giving it fuel to get going lol. I'm used to having so much torque where I can put it in 3rd and still start off without giving it fuel.

I will say i double clutch when under a load, but play around when Bob tailing or running empty, as in floating.

Umm sloppy transmissions are from drivers forcing it into the slot not from floating or from resting their arm on the shifter...proper RPM matching is always required. Also a sloppy tranny is rarely an expensive repair, the bushing for the SHIFT TOWER not the TRANNY can be had for under $30 add in the 1/2 hour labor to install them by any competent mechanic (most shops charge a one hour minimum so lets call it 1 hour) for $70 and your shifter is as tight as the day she rolled of the assembly line.

 

Hmm, I can shift my Colorado from one gear to the next as fast as I can throw the shifter single clutching with ZERO grind. Sure would think they would have that kind of technology in their top of the line sports car.

 

too much rpm drop doin that....your colorado trasmission isn't a 6 speed high perf trans either

i didnt say have the jake on when shifting, i said i leave mine on all the time. and i also said that is a problem for new drivers out there attempting to learn how to float gears. they forget to turn the jake off and that will make them miss gears ten times over due to the rapid drop in RPMS. and when the gear missing happens, the frustration level rises, and then they are all messed up and out of place.

when you float gears and the jake is on, you simply have to be faster at getting out and in to the next gear before the RPMS fall down below the gear requirement.

all you hear in mine is the snap of the hi-low switch. once in a while when i am loaded really heavy, i will wind a gear up a little higher and it might upset the transmission and make it grind for just a second, but that is all in the timing of the shift.

in the end, it is all about the RPMS vs road speed. you can still screw it up with the double clutch method too. and in my opinion, the biggest problem with the double clutching is that some hardheads fully depress the clutch each time, and what does that do?? well when that pedal goes to the floor, you are activating the clutch brake. and that is a whole other problem in itself.

 

I'm in school now and getting through the gears is no problem, even with double clutching but down shifting is killing me. I wish we would get to practice in the same truck but we've gone back and forth from a 9 speed to a 10 speed every day so far. I better figure it out quick because we test out this week.

 

Jack..

two things that goof up downshifts..

Not enough bump in the rpm or two much bump in the rpm and the driver tries to go into gear too soon

fix for both..practice..You'll get it..just remember to try to keep your frustration in check..its hard to do but the more frustrated you get the worse you get..

You'll get the hang of it

Thanks Petey. Frustration and a pitiful instructor are what's getting me now. While I understand that Rome wasn't built in a day I like to think that I pick things up rather quickly. Driving a 5 speed isn't helping any either. I seem to have everything else pretty well handled, but down shifting may be my down fall. In the real world, how much down shifting do you do?

 

Downshifting depends on a lot of variables. Ill let the experienced drivers tell you how it needs to be done.

I only downshift when i need to. If I'm empty or Bob tailing then I won't downshift. If I'm loaded I always downshift.
