You can hear if it's locked or not. I was returning from Hallett a jillion years ago and found myself unlocked in 4th in some crosswind for like 15 minutes. When I finally looked down the trans (not a 4L60) was rocking out at like 230! I pulled it back to 3rd, let lock, and the temp dropped like a rock. Just gotta keep an ear open for it.
