Hmmm, If I look it up on google and what not on wiki (which i hate using) it says for cobalts the f35 is one of the transmissions that was used. So I clicked it. And got this info:
2005-2007 Chevrolet Cobalt SS Supercharged (MU3)
2008-2010 Chevrolet Cobalt SS Turbocharged (MC2)
So, I went back and clicked f23 and get this:
2005–2007 Chevrolet Cobalt
Then come across this:
Optional for the LSJ was a performance package coded G85 that added Recaro bucket seats and a limited slip differential (LSD). LSD was optional for 2005 models (performance package came with LSD) and was standard in 2006 + models.
Then under the naturally aspirated ss I get this:
The 5-speed manual is also different from the Cobalt SS Supercharged, it is the Getrag F23 transmission with different ratios that is offered for the 2.2 L L61 engine in the Cobalt LS and LT.
