Read that link. The 6 speed in europe uses more gas than the 5 speed in the extra urban cycle. It is also slower in acceleration. May not be the awesome swap idea we all thought it might be. I also noticed it looks like the 9-3 uses the same front suspension as the cobalt ss with the 3 bolts holding it on. Cobalts may be able to use their coilover kits. Lastly...we are the same chassis as 9-3...it has independent rear suspension. I'm wondering if we could bolt their rear suspension and crossmember in inplace of our torsion beam. Don't know if we'd actually notice a difference but we could then use their coilver kits and crap...but our rear suspension handles pretty good right now as it sits. The torsion beam can work...but a multilink sounds awesome...but would you ever notice the difference?

EDIT:

Also I figured out why we can hear the marble in a tin can noise and why Saab owners do not. I used to work for a clutch manufacturer in testing and tuning. What we hear is audible some at idle and some at WOT but it is really audible under decelleration. What this is is exactly what the TSB states...It is gear rattle. Gear rattle is when engine harmonics (NVH stuff) get transferred into the gear box causing the gears to rattle...Its just like a vibration. A way to get rid of this without hanging external dampers or such on the outside of the transmision is to use a dual mass flywheel which is a damper similar to the one in the clutch disc but tuned to get a cancel a different set of vibrations. Well guess car has a DMF and which does not? You guessed it the Saab 9-3 has a DMF and the ION Redline does not. In our tsb they just place clips on the gears so they cant rattle around. With the DMF they dont need those cause the engine torsionals never get inside the gearbox. I imagine putting a normal flywheel on a 9-3 would make it loud. also a dmf is much more expensive than little clips to slide on the gears...so that is probably why we don't get a DMF as a fix...plus they are about 2 to 3 times as heavy as a normal flywheel...which sucks for performance but can make a car easier to launch due to inertia. That is probably the cause of why our cars are soo touchy to launch technique as compared to the Saabs. I'd also venture to say that the Saab has a much different pedal feel/engagement point.

I think that is it for now.

i got "forbidden 404"

now its working

SilverSS/SC

Saab 9-3 is on the Elipson Chassis , same as US G6 and Mailbu . The only thing we share with it are its 2.0 engine hence the turbo , and the F35 SS/SC 5 speed trans .
