Shifting
*Points to signature*
I want to know where I should be making my shifts. What RPM's do you guy usually make your shifts at. Also, what is the highest you guys wring it up to - or how high do you dare? I've only had it up to just over 3000 rpms (at any time), and there is not "redline" on the tach, and it goes all the way to 6000 - is the engine able to hit that rpm. I understand that the engine would be useless at this rpm, but I'm just curious.
As for the shifting, where do you guys shift between "babying" and "toying"?
so far I've been shifting at about 1600-2000 for babying, and about 2300-2800 for toying. This bad?
Lastly, how are the clutches on these. Will I burn my clutch up? I generally when I go I bring it up to about 1200-1400 rpms and hold the clutch in till it gets going a bit...and my grandfather yelled at me when I was doing this saying that I needed to launch it cleanly (hardly any clutch use) but I find this to cause the truck to jerk more which isn't cool. Just...thanks for your help guys.

I have a 98' F150 M5OD 3.55's with 4.2L V6.
The HP and torque curves are different than those in your I6, so my experience may not entirely apply to your machine.
But the way I see it, RPM's are still RPM's right? For the most part anyway.
The M5OD is a light transmission with no granny gear needed for heavy loads, but it has a 3.91 1st gear, which is quite a bit lower than second in the ZF 5 speed, so I would say I agree with grandpa there- no reason you can't launch clean in 1st without a load and without jerking it. The clutch is weak, and if you get a better aftermarket one with some beef on it that would help out alot.
I rev up to 3000 RPM in every gear except when going into OD from 4th which I take to about 2500 RPM - this makes for smooth, positive, and powerful shifts everytime. At this RPM I need only let off the accelerator, make the shift, and let the clutch back out BEFORE tapping the throttle again- it's lot's smoother, and causes much less clutch wear than trying to syncro your right and left foot together.
With a six speed with closer spaced gear ratio's I'd probably only need to rev to about 2300 or so to get the same result, especially with a lower geared differential.
Man I miss granny gear......
