Most people get the rated torque number from GM's own naming system. The F35 used in supercharged and turbocharged Cobalts refers to the 350N*M of torque the transaxle is engineered to handle.

 

yes, but like i said just because it is an f35 doesn't mean it is going to be identical to the ss/sc's tranny. example: the 5r55s transmission (automatic) in the 2005+ v6 mustangs has the exact same name as the 5r55s in the gt, but the input shaft is smaller (weaker) and some other minor differences make the 5r55s in the gt quite a bit stronger, but on paper it would seem they have exactly the same transmission.

 

Ford doesn't designate their transmissions by their rated torque.

 

Don't you love when people grasp at straws???

 

No kidding.

 

what are you talking about? f35 has nothing to do with the torque rating. That is MU3. The TR-6060 in the z06 is called the TR-6060 in the zr1 and gt500 as well but is internally very different. THis is where the MH3 vs MM6, etc. comes into play. Has it been confirmed that the MU3 is being used in the new ss? Otherwise, the f35 in the ss/sc could be different than the f35 in the ss/tc.

Anything else I can help you with?

 

ahhh see thats what i was looking for. Nobody anywhere else could tell me if it was the MU3. i guess you are all fucked then. sucks.

 

no, ss tc is fucked. Not us.

 

nah you're all just fucked. 260 ft lbs = poop. what are all the turbo guys gonna do? those trannies aren't lasting long. what matches up tranny wise? f40?

 

I don't know what the tranny code is for a '03-'04 cavy with the 2.2 ecotec, but I'm considering trying that swap as I'm a drag racer and those trannies have WAY better gearing for acceleration.

 

It seems like the SC guys are doing the same thing to the upcoming TC like the Terminator guys did to the GT500 when they found out something else was going to be top dog. They are trying to find flaws in it to make it look like they still have the better car.

Here’s the way I look at it, GM knows that this is a tuner car and will be modified so why would they put the same trans in a car that is going to be making more hp and tq stock and be easier to mod. Like cakeeater said it would be nothing for them to upgrade the internals of the trans, that was what was originally done to the GT500. All they did was put a beefed up T-56 in it at the beginning and then decided to put the T-6060 in it later into the design.

How much longer is it until the TCs go into production? They can make changes with less than 3 months till production starts, Ford did that with the 03-04 Cobras. I just think you guys might be surprised what happens. They could keep the same trans in it but the very well might change it also. Either way it would be nothing to beef that trans up for $1500 and have a very solid trans, which the same would go for you guys also.

 

Well, they already changed the final drive ratio from 4.05 in the SS/SC to 3.87 in the SS/TC. It's possible that they could have changed something else. We'll just have to wait and see.

 

But who wants to drop $1500 on a rebuild for a new car? Not to mention the issues that'll bring up with the cars powertrain warranty.

 

Uhhh the same people that add nitrous, superchargers, turbos, exhaust, ect to their new cars. All those void the warranty and people still do it. If you’re worried about the warranty you shouldn’t be racing or modding your car anyway because the manufacturer can void you warranty if they see any mods or signs of racing or abuse. Plus if you get the trans built by a good shop you shouldn’t have to worry about it breaking and that wouldn’t affect the motor warranty anyway.

I didn’t have my car a year and the warranty was long gone. The car didn’t even have 10k miles on it by the time I had full exhaust, Vortech Supercharger, Paxton A/A IC, 4.10 gears, and an upgraded fuel system. By 20k I had a built motor, cams and another fuel system.

 

how bout you post somewhere other than war stories?

 

f23 same as the 2.2 and 2.4 cobalts.

 

I think you guys are taking this tranny issue way out of proportion. Just because you have 261+ lbs of tq, doesn't mean you're going to blow it up. You have to take into consideration as to how you drive/treat it. If you beat the **** out of it, of course it's going to blow eventually. But I do not think people will have tranny problems with this 260 ft/lb rated tranny except the morons who beat the ever living **** out of their cars.

 

You've misunderstood me. My main point was about people probably not wanting to drop $1500 on a transmission rebuild after a few basic bolt-ons and maybe a tune which would probably be less than $1500 anyway, on a brand new car. The bit about the warranty is just because a lot of people use the car for a DD and seem to care about having one.

Note: I'm not saying the tranny is only rated for 260ft-lbs I'm just making a point about it.

Think about it like this. You can have a car making 500bhp and 500lb-ft with a clutch rated for 450lb-ft and it'll run fine at first but the clutch will wear faster. Similar logic can be applied if the new balt's trans is really only good for 260lb-ft then it'll begin to fail sooner based on how much you increase the motors torque output.

I've seen Chevy do some stupid **** in the past but I doubt they'd really put a tranny in the car thats already at it's max rating.

 

^^^Fix0red for you.

 

I still think it's going to be fine...just my personal opinion

 

Is the LNF and the LSJ have the same tranny?I thought LSJ had the F30 and the LNF F35

 

Agreed. But most people are crying rivers because of this. They are over reacting when everything will be fine. I had a stock clutch with a 2.5 pulley and many passes down the track until 36k miles on the car....EVEN THEN my clutch was still strong. The shop that did my clutch gave me the clutch back and said I could use it as a spare. It had some heat marks on it but is fine and grabbed fine right until I swapped it out. (That is an example of how driving a certain way will prolong parts. I remember everyone was saying the cluthc is the biggest pos ever...Well I don't think that at all. People just beat on their cars 24/7 when they shouldn't be and just don't know how to drive correctly to prolong thel ife of parts). I'm gonna stick to my opinion. The trans will be fine with more power except to the idiots who beat the crap out of their cars.

 

Nope... same same. In the Cobalt at least... I'm not sure of the LNF-HHR trannies.
