Hey mike got the tranny out of my dually and was gonna take a peak inside and wanted to see how much for you to send me a c3+c4 gmax upgrade kit and front and rear housing gaskets. Also you built this tranny originally probly 4-5 years ago with the previous owner and I was wondering if there was anything secret I need to look at doing while I'm in it. Tranny is still holding good power by the way I am just heading towards a lot more power and want to make sure I got the tranny to hold it. Any advice/input/recommendation is appreciated. Thanks!
