As I have learned in all my gear griding experience after the 4.10 was installed is that shifting has to be done at a completly different level. I have learned that in first gear, in order to actually get it into second I can't go over 4,500 or else it won't go, same with sencond and 3rd. Is this pretty correct? What's a proper shift procedure when launching an m6 with a 4.10. Any advice on how to adjust without damaging the trans would be greatly appreciated. Thanks.

 

You have something wrong, clutch, hydraulics, tranny, I have 4.10's and 6600 rev limiter and it shifts fine ( when the clutch pedal doesn't stay on the floor)

 

ok good....so that means my trans is acting funny. I have tried to shift from 1 to 2nd at 6500...well lemme ask you this, do you power shift, while still flooring it or do you let go of the pedal, shift and then floor it again. I was probably doing it wrong....I will try and get back. I was shifting like I used to shift my suburu. While still flooring, and at 6500 the trans's won't let go of the gear even when the clutch is hammered down.....

 

I don't recommend power shifting but you should be able to. Until it breaks anyway!

 

Powershifting at redline is likely to make you live up to your board name if you don't break

But, it sounds fun..............

 

When is the proper time to shift with 4.10s? What should I generally keep the tach at when I'm driving under normal conditions? Thanks.

 

Well, for me ... during normal daily driving, I shift around 3000 RPM. I stay in 4th on side streets, 5th on main roads, and 6th if it's a long drive on certain roads, and 6th on interstate.

At the track, the shift light comes on at 6K and I don't lift the gas. I just stab the clutch, rip into the next gear, and get off the clutch. The right foot never moves.

 

Yea you should be able to rip into the next gear at any rpm when you don't flatfoot-shift it.

Daily drive shift at 3k? Hmmmm.... daily driving mine with 3.73s i shift at 22-2300 using a "4-speed" procedure using gears 1, 3, 5, and 6. Makes it much easier to drive and saves wear on your clutch, TO bearing, and it's hydraulics. It'll be even easier with 4.10s. But mine is primary transportation at least for the next2-3 years (unlike many people) so longevity is a special concern.

AFA tach position, i find that as long as you don't creep below about 1400 on the shifts with the stock cam it'll act well-mannered. Just my $.02.

 

when i feel saucy i dont lift ...my friend who taught me how to do it, does it a lil more hardcore though...he rips the car outta gear and only uses clutch to get back into gear ....he just replaced his tranny a couple days ago lol

 

I'm usually on the highway at around 65 mph and I'm not sure whether or not to put it into 6th. If I do, the tach reads between 1600 and 1800. Is this putting strain on the engine?

 

fast caddie is right
just don't let it get below 1400 (i usually like 1500) and it'll be fine

bluerave, the manual actually says you can put it in 6th at 50mph (no less)
i usually wait til about 55-60
and yea, it is actually putting stress on the engine because it does tend to work harder in the overdrive gears
it's no problem though just cruising
just remember to downshift when passing

 

What manual are you refering to? I assume you are refering to the owners manual -- aren't those numbers useless when you upgrade to 4.10 gears? So 1500 RPM in 6th gear is fine for extended cruising?

 

all your gears do is multiply that torque really
i suppose since the rpms change, you can downshift into 6th at say 45 hypothetically
i'd say 1500 is fine for extended cruising, jmho
