No they are not the same. The SC uses an F23 and the TC uses the F35. The F35 is significantly stronger than the F23. The F35 will live at 320 just fine, However when you throw more than 275 at them for several thousand miles they tend to get gear whine that sounds like straight cut gears just not as loud as that. (in other words they pick up a little whine) But the F35 and axles in the TC are way more robust than the SC's F23 and smaller axles.

but if that was the case it would not make sence to put the same tranny in this car!

Specifications
Type: transverse front wheel drive, five speed manual transaxle.
Engine Range: 2.0L
Max Gearbox Torque: 258 lb.-ft.
Weight: 99 lbs.
Applications: Chevrolet Cobalt SS, Chevrolet HHR SS
Both the LSJ and LNF Cobalts use the same transmission. The only difference is the clutch. The Clutch in the SS/SC was only rated to like 220 hp which is why alot of people had problems with them once they upgraded to stage 2. Gm even specified (if you bothered to look) that the stock SS/SC clutch would not hold up to the power of the Stage 2 kit. I believe the SS/TC clutch is rated to like 300 hp, though if you look at the GM specifications above you see the transmission is actually only rated to 258 tq.... Since they changed the final drive to 3.82, the new gearbox maybe a little stronger but I haven't seen anything on it.

No they do not use the same transmission. I work for GM service at GM and I can tell you for fact they don't. There was a thread in here about the F35 in SC's and comments about issues surrounding it. That thread was wrong. The SC has used the F23 from the get go and the TC is the first to use the F35. My Buddy that sits next to me has an SC and I have a TC and the transmissions are not the same.
The F23 has a sheet metal end cover on it and the F35 does not. The F23 is still used in the non performance Cobalt and G5 variants

Both supercharged and turbocharged Cobalts have the same F35 tranny. SS/tc does have an improved clutch and slightly taller final drive, but that is it. Exact same gear ratios.
Gettinausernamesucks, look at the gear ratios between a ss/sc and a 2.4 or 2.2, and tell me they both have F23 trannies in them. It's just not the case.

Ok guys
I was wrong. I gotta eat crow here. My partner and I have had this discussion a zillion times and you are all correct. The SC does in fact use the MU3 F35. Must be to many long days as the pressure at the big house is getting pretty ugly. And I even work for service. Now how bad is that.
My bad, I apologize.
yes the clutch and flywheel are different and are the axles.

....assuming your numbers are acurate why would GM being comming out with a stage 1 kit that has at least 290 HP and over 260 ft lbs of torque. The engine already make 258 ft lbs or torque with is already 2 ft lbs over the rating limit. I would think they would have many tranmissions to fix under warrenty...
