When you have an 11 sec. car, everything is like $900 to make it go 10's. When you have a low 9 or high 8 sec. car, everything is 4K to get it to go faster! After you spend the money and get the trans. you still have to deal with the converter, flexplate, trans. X member, starter, driveshaft and shifter, none of which are cheap. Stupid money...
