I fit one to the transmission because of a minor crunch on the initial 1-2 up shift of the day before the gear lube warmed up. That was 2 years ago, and it hasn't recurred since.

I installed the detention a few months back to address the same issue and it has not happened since.

The 6sp trans has a 2nd gear pop-out issue. I had to rebuild mine at 142k. I did the G-box detent, I'm at 180k no issues.
