46RE Geartrain Lock Gizmo

thingiverse

It can be a pain to get the overdrive section onto the park rod of a 46RE. This gizmo will fit on the end of the Output Speed Sensor and allow you to lock the geartrain in place. Simply get the geartrain into a position where the park lever can engage, and screw the speed sensor back in with this thing on the end of it just until it is tight enough to keep the output shaft from turning. I used TPU because it needs to have some grab to it and be flexible. I made the walls and the top and bottom 2mm thick in my print settings.
