I am not that mechanically inclined. I am more of a body and metal work guy. So any info is helpful. I had my buddy put my engine and transmission in and I have had him work on many of my toys. There is a hole on the back side of my transmission on the right side. Almost perfect circle but has no screw threads. Just a hole. If anyone can tell me what this is for and what to put in it that would be much appreciated. Pictures are attached below. Again any info would be really helpful. Everyone I have consulted has no clue.
Thanks, Michael
