A. Your transmission will arrive with approximately 1-3 quarts of full synthetic ATF in it from testing. The torque converter is already primed with fluid and does not need to be removed. You will have to top the transmission off with fluid before operating. We recommend using our full synthetic ATF or any popular brand full synthetic ATF.
