Ok, so it looks like I can get a 4l60e transgo kit for about $45 and then the beast sun shell gear for $50-$60, does that seem right? Would this cause any problems putting it onto a stock, original transmission with 180k on it? It says it fixes a few things, including the hard shift from 1-2, which I get a lot.....so I'm thinking about putting this in, just wondering what else I might need to know. Does it strengthen the transmission overall, or do I need to do something else to build it up?
