I have to rebuild my c4. Im not a transmission guy. Wondering what kind of upgrades can I do. I don't want just a stock c4 rebuild but willing to spend the extra $ for a rock solid heavy duty tranny. 75, 351w 300hp? going to increase hp someday to 400+. Thanks

With the upgrades to the clutches, valve body and torque converter the c4 can easily handle 400 hp

Start here, lots of good upgrades. The biggest issue is trying to keep it cool.
