Sporadic reports have begun popping up in the Camaro5 forums about issues with V8-powered SS models equipped with the manual transmission. It seems that doing a hard launch or using the launch control system occasionally results in a broken output shaft, a serious failure that will most likely leave the car immobile and in need of repair. We spoke with General Motors spokesman Adam Dennison about the problem and, as this is being written, a factory hold has been put on deliveries of manual transmission V8 Camaros while Chevrolet engineering teams investigate the problem.

Based on the reports, the transmission issues may not be related to the launch control system as the failures seem to happen whether or not launch control is engaged. The Camaro SS uses the Tremec 6060 six-speed gearbox – the same transmission fitted to the Dodge Viper, Mustang GT500, Corvette Z06 and other performance cars – so this is likely a manufacturing issue with a batch of gearboxes.

Dennison told Autoblog that an engineering meeting is being held this evening to identify the cause and establish a timing for the fix – and a recall seems likely. In the meantime, if you have a manual model Camaro SS, you might want to go easy on the launches for now – and if you have one ordered, you'll have to wait a bit longer.
