or it must at least be in inside the bell housing when the trans goes in.... you can always mess with it and get it where it needs to be afterward, or if it pops out, but def try to keep it in its bracket.... i don't know if there is enough room between the flywheel and the outer edge of the housing (where the inspection plate goes) to actually slide it in there after you've mated the trans to the engine, but i want to say that if it falls out and ends up down there you can at least use both hands to get it back into the square hole, then maneuver it into its bracket..... i think i recall having to do this (i have a horrible memory)
