I need a transmission that is capable to handle 750+ hp. Performabuilt lvl 3 trans claim to handle up to 800 hp for $1100 less than RPM or FLT lvl 7. They also offer free shipping, free tranny cooler, no core charge, and 1 yr warranty. if anything goes bad after warranty expires, they will rebuild the trans for $850. Sounds like a great deal. Anyone is running these trans, or heard anything about them?
