M6 guys... T6060 is a POS !!
I seems that the gt500 guys and the corvette guys are having one hell of a time with this transmission. It seems gm is really not helping them out to much.
http://forums.corvetteforum.com/c6-z...e-trannys.html Gt500 same issue http://www.svtperformance.com/forums...ghlight=tranny Sure hope they iron all this out for the 5th gen |

not good news! considering it ONLY happens when the tranny is cold and its only 1-2 and not all owners are having issues, it doesn't seem like a major design flaw

Just skimming threw the threads you posted looks like these trannys are being abused.

Sounds more like a clutch issue for the Mustangs anyway. As for the vette problems, sounds more like the synchros are hanging up and I would think it would get better with miles. However, I would be pretty upset if I took good care of my car and it started grinding gears like that.

I've talked to a couple of my vette buddies and they all say the same thing "thats just the way the transmission is when its cold".
I used to have a chevette diesel (quit laughing) and it was the same way for the first mile or two of driving when it was cold. It was'nt an issue in warm weather, and it was'nt much of an issue below zero. It was just stiff to shift for the first few times through the range until it got warmed up. Everything shifted smooth...no grind etc....it was just as if the trans fluid was as thick as mud.

This tranny should be stronger than the T56 from what I have read on the specs .. I'm not to worried about this ... you always have some folks that abuse the trannys ...

I'm just a bit worried because the time they say it takes to warm up is longer than it takes me to even get to work heh.

Doesn't the Challenger 6.1 Hemi use this same tr6060 manual transmission as the Camaro. A salesman trying to sell me a Challanger said the 6 speed manual was delayed with transmission and clutch problems.

It's no slick Japenese transmission. But then Japenese transmissions don't have to handle GOBS of torque. They would go BOOM.
Many Vette owners put Royal Purple tranny fluid in (not GM approved), and lighten the action up, especially when cold. The automatic trans is no gift either. It searches and hunts for the right gear - most automatics do. There are trade-offs for the neck snapping, amusement park torque instantly available at any RPM. And yes, Corvette Forum is a terrific place to get more info on these types of things. (Like LS3 real world experience). |

This same issue was mentioned quite a while ago, I don't think the term POS applies, you're being dramatic. It was determined the first time around that the grinding could be caused by poor shifting technique. I love it when you get people brand new to the site posting stuff like the sky is falling.
