Look what I found through GM Powertrain!!!!!!!!!

I was doing some search regarding the TR6060 and came across this on GM Powertrain website!!!! Post your thoughts, comments and rants......

Second Gear Synchronizers Using Carbon Material
The change to carbon material on the second gear synchronizer will improve the durability of the synchronizer. Carbon also protects the synchronizer during WOT shifts with the wheels spinning. The shift feel improvements made in 2008 are refined further with the implementation of the carbon material.

If GM didn't see any issues with the TR6060 (M10) then why the change to the carbon blockers to improve shift feel? Just by writing this they are admitting to the issues these transmission are having.

Second Gear Synchronizer Design with Advanced and Asymmetric Teeth
Implementing advanced and asymmetric teeth on the second gear synchronizer system improves the shifting action of the transmission during cold temperatures. This is accomplished by the advanced and asymmetric teeth contacting the second gear dog ring in less distance and with increased stopping power. The shift feel is significantly improved in cold weather. This design also improves the warm shifting comfort.

Again, why the redesign if there was nothing "wrong" with the transmission. I have seen the asymmetric teeth (5 teeth I think at 120* apart on the synchro between the synchro keys) and throught it was weird design.

So GM completely dumbed down the TR6060 for the Camaro's as compared to the vettes?

Awesome GM. Awsome.

Haha . . . I actually think they are quite far from admitting to the issues the previous models they're having. They've chosen their words very carefully. By writing this, they have a new selling point for the newer models 2011+ to avoid future complaints, and effectively avoid having to offer warranty work for everyone with a POS transmission from 2009 - 2010.

Because the internals in TR6060's for the Z06 and ZR1 are completely different then what's in the SS.....

Are the 2012 Camaro's suppose to have the upgraded internals?

All TR6060's are the same except for ZR1. They share the same synchronizers and bearings but the gear ratios (teeth counts) are different. Also the layout is different between the Vettes (rear mounted) and Camaros (engine mounted).

The 2011 and 2012 TR6060's only have the upgraded carbon blocking rings in SECOND GEAR ONLY.
