Ok so i recently had one of the ears on my transmission welded back on from previous damage. Before I took it to have it welded, I took off the side cover to visually inspect the gears and internal parts. Although I am not an expert, everything seemed to be in good shape. However, once I took the cover off and held it upside down, there was a ball-bearing rolling around in the cover. It was about 1/4" in diameter, and my dad suspects its some sort of detent ball for the shift forks?! I really need to install this replacement tranny ASAP, if anyone has any exploded diagrams or general information as the where the bearing belongs I would highly appreciate it!!
