I paid 350 for mine. Of course I am on my 4th one. Lets see, original 1987 build tranny burned up a week after my 496. Rebuild for $300. Then torque converter bearing came apart, rebuild for $350(hadta replace all the tranny hardparts except case and output shaft). Then my forgetting to clean out the tranny/tcase adapter plate, put metal back into the tranny, so another rebuild, but it was just cleaning the valve body basically, but got charged $10 for new gaskets. So yeh, 4th tranny.
