I just picked up a 2010 and my buddy goy a 09, I was wondering if anything internally on the trans has changed from previous year 6 speeds? I question this cause eventualy both are gonna get a stage 4 kit from MikeL. For now they are going to get just a Transgo Jr tell the new business starts makin some money. The reason I question internal changes is I heard that the 2011's get a TCM controled line pressure :D Just wondering since we dont have access to the 09+ TCM's with efi yet that maybe some early revisions may have taken place on the 2010 doubtful for the 09 but obviously they both got the new TCM.

The 2010 i put a transgo jr in was the same as the 09's that i have done. The only difference was the stock trim valve springs were orange on the 10's and the 01-09's are black.

Mike will hook you up :thumb:
