Where is this xcase drain plug lacated at on my 2k blazer? Is it the one next to solenoid(black tubular or cylindrical) or by the rear of xcase. And i've heard there is another one plug for filling her up with autotrac II. I appreciate your help.I always like to read this forum but i can't find the answer and if there is a pic that would really help for any one here.Thank you again.
