f35 mu3 transmission
 

Ok, my 2010 hhr ss has a f35 mu3 but does not have an lsd. I did get a 2006 cobalt f35 mu3 with lsd for a good price. I am having a problem locating information as to model I should buy the new clutch for. I was going to use the balt transmission as it is because it is in good condition and swapping out differentials is such a pain in the behind. Most clutch listings say the two use different clutch kits although I have found some that say they are the same. Anybody know for sure?

Search TTR and ZZP sites, they both should shed some light on this

2006 Cobalt was the supercharged engine, correct ? That may be the reason for the 2 different clutch kits you're seeing.
Since the turbocharged HHR put out more HP and torque, it may have had a little stronger clutch from the factory than the Cobalt did.
