Im a long time technician my trans is not long for this world lol. Anyway I bought a new one & want to put what it needs to make it bulletproof to 500hp ish. So basically Id like a list of what you all have done. I also want to know if anyone has installed a Sonnax 2.84 Ratio Input Carrier Kit. I love the close ratio Idea because its better but don't know if I should, It ant cheap??? I know theres lots of after market tranys out there but being a tech Id rather do it myself (also get parts cheaper).
