I have 92 toyota pickup 22re auto 4x4 . I changed shifter bushings today then afterwards I had a buzz in the transmission pan. Played with linkage little no change pushed on a sensor near the shifter lever on trans right next to on right side and it stopped for a sec it wasn't doing this before I changed the bushings though. I figured maybe between gears or not all the way in park but I am stumped . Any ideas

 

Only makes noise in park
