Hey Guys, question I blew the 3rd and overdrive gear on my tranny i have a 4.8 silverado 2004 right now im actually still driving it cause its the only car i have and right now. I was wondering what would be best to replace it since ima do some mods to the engine which actually include a pair of 76mm turbos , i was thimking of a 400 II turbo tranny or a six speed. Honestly i dont know what would be better any help would be greatly appreciated.
