This seal is located in the front of the transmission. Its called a front input shaft seal. You will need to drop the transmission and remove the torque converter. Once the converter is off if you look at the shaft protruding from the transmission just at the base of the input shaft you will see this seal.
you can rent a seal remover from you parts store, IE Autozone or Oriely's and rent the seal installer tool. This will insure that you do not damage the seal housing or the seal when installing the new one.
One word of advice would be to take the torque converter to a transmission shop and have it checked before reinstalling it. If it has a worn seal face or has a bad set of blades you would be money ahead to replace it while your doing it the first time and not have to pull it back apart 3 months later.
