Just bought a 95 Camaro for a daily driver. Has a 3.4L V6 with 107K miles. Seen some definite use, but all things wrong are easily repairable. My biggest concern is a transmission fluid leak from the rear where the yoke leaves the transmission. I believe its a worn rear seal. The replacement seal is $2. How easy is it to remove this seal and replace it? Does it involve special tools? Will I have to drain the transmission fluid? Any help would be appreciated.
