So we get stuck with low end Tremec?
Looking around for more information about the Tremec TR-6060 tranny, I came across a GM link with info about the different types of tremecs. Basically the tremec in the Camaro is only rated for 430 lb -ft. of torque. All along I assumed it was 600 lb ft. according to the Camaro5 wiki.
I know its a cost cutting measure, but leaving only a 10 lb ft. torque difference in the specifications? Gm Link - http://media.gm.com/us/powertrain/en..._MG9_M10_n.doc Low maintenance The TR6060 6-speed uses Texaco ATF Type III 1863 fluid and is certified "fill-for-life," requiring no fluid changes. The clutch is activated hydraulically, which automatically compensates for clutch disc wear, eliminating manual adjustments (except for the ZR1 which uses a traditional clutch). The Tremec TR6060 six-speed has evolved from a design that aimed to require virtually no maintenance in all but the most severe conditions. Overview Both the standard Corvette and the high-performance Z06 use the TR6060 designated as MM6, which is validated to 500 lb-ft of torque, while the TR6060 with the Z51 option features higher ratios and is designated as MZ6. It is validated to 430 lb-ft of torque. The ultra high performance ZR1 uses the TR6060 designated as the MH3, which is validated to 650 lb-ft of torque. The CTSv uses the MG9 version of the TR6060 validated to 560 lb-ft of torque. The Camaro uses the M10 gear set validated to 430 lb-ft |

doesnt say that it broke at that power, just that its capable of holding that power... which is roughly what the LS3 puts out... isnt it?
you are reading too much into it. how much power does the Z06 make? ~500hp.... the ZR1 makes around 650hp.... CTSv makes around 550hp.... do you think GM is going to put a transmission in there that can juuuuuuuuuuuuust barely support the existing power of the motor?

That being said, the CTSV's TR6060 probably does have some noticeably upgraded internals that makes it differ from the base vettes and camaro's. |

Don't get your tech from any Wiki page.. it's only as good as the person writing it. lol I have two TR-6060 varients in my shop and I'm currently working with Tremec on a tech story explaining the difference between the TR-6060 (T56 Magnum) and the T56... Being rated in the 400s is nonsense and the person that wrote that isn't very well informed.

Then again, on street tires you could run 1000 hp though the trans since it will never hook. Hard shocks is what kills transmissions. The main differences between the various TR6060 varients is in gearing and in the front case/tail shaft areas. Acutally most have the same gearing except the ZR1 which has a very close ratio setup. I will talking with the Tremec guy all next week.. what questions do you want me to ask?

Oh, and I assume that the different variants all use the same housing, shaft design, bearing support locations, etc., so what (besides ratios) really changes depending on application? Do they use higher grade steel for the higher hp cars?

I would hope not but given the 10 bolt rear end in the previous generation, it wouldn't be totally unthinkable.

Since the TR6060 uses a remote shifter system that's the biggest change.. and of course there would be differences base on whether the target car is IRS or live axle. I have the aftermarket version (called a T56 Magnum) in my orange '68 Camaro. The big diff there is that it has a direct (more traditional) shifter, but the internals are identical to the OEM version. I will ask them next week about differences in internals.. but I'm pretty sure they are the same from a strength standpoint.

It's not GM's responsibility to over-engineer parts so that people can run slicks, add blowers, or do other changes to the car. I found it fascinating that someone would add slicks, toss on a 200 shot of nitrous and then complain that the "crappy" rear blew apart. lol

I understand not having to engineer stock parts for people with FI, nitrous, etc in mind, but SLICKS? Come on now, there are countless horror stories on ls1tech about people blowing up their rear ends on sticky tires and STOCK POWER. There are also a few about DONUTS on street tires killing 10 bolts. The way I see it, durability involves the purposeful over engineering of a wear item. The fourth gen wasn't an economy commuter car - why would they design a rear end that could juuuuust barely handle 300-350hp on street tires?
