Who exactly, are you locking-out from checking your transmission fluid level? All that red push-pin does is shove the "grasping claw" of the cap completely underneath the rolled-metal-lip at the very top of the trans fill-tube. The cap's "grasping claw" already comes into contact with that lip such that you have to pull up with some force to overcome it and remove the cap. So even without the red locking-pin there's no way in Hell that transmission cap is coming off by itself! (Which BTW, is my entire point) Why would you ever reinstall a lock? Who are you securing access against?
I really do it know, locking it in position means it will not fallout, I have no idea how tight it is.
Someone could put engine oil in it.
I am just stating what was previously posted, this is not the only mention of the clips reuse on the forum. As the old saying goes ‘Do not shoot the messenger’.
