cobalt ss/tc and the hhr ss share the same manual tranny???

 

Someone on here said no but it's the same tranny make and code from what I read. I don't get it either.

 

hmmm...guess i gotta call the stealership. i want to upgrade my clutch and clutchmasters make one for the cobolt ss. it's still slippin like an old man in the tub. only when i hit 21 psi though.

 

I've been waiting for a definitive answer on this myself.

Torque is an awesome thing!

 

One would assume yes . . . the cars are on the same chassis . . .

 

The transmissions are both MU3s trannys but are geared differently. The have seperate part numbers. The clutches are the same.

 

that's all i wanted to know...same clutches . next mod...clutchmasters here i come!!!

You've not steered us wrong yet but why are so many saying they are not the same clutch? Can you just double check to be 120% sure?

It'll cost me $1400+ if your wrong!

TIA

 

Well i don't need that on my conscious! I have never figured out how to be more than 100% correct????

Here's what I have. Both the 2008 HHR SS and 2008 Cobalt SS show a part number for the Disc to be 24239997 and the pressure plate is 24239996. Now you can check with your local Chevy dealer to verify both those part numbers are correct for those vehicles. Other than that, see my signature for further disclaimers.

As to why others say they are different, possibly they base that on the fact the transmissions have different part numbers.

As far as getting one from an aftermarket company I can't help you on that. I would call them first before you make the investment.

 

From what I also show they take the same Clutches in my catalogs. ChevyMGR is very correct.

The ratio is different in the cars since the HHR is heavier.

Anyone wanting to wail on the HHR and add more power you had better plan on a better clutch and don't cheap out. The factory clutches in most new cars will take stock perfornmance driving but they have their limits.

It is like the Mustang guys, there are two types of stock clutches in a modified Mustang Those that are slipping and those that are burned up.

Also consider as you beef up the clutch the next thing to look at is axles and the diff. More power and hard driving will show the weak spots. If you can't remove a transaxle yourself put some money asside for repairs later you will be glad you did.

I have been though this before myself on some of my past cars and I deal with broken perfromance part daily as part of my job.
