Tranny explosion

I rolled the sprag last year. Just barely cracked the case. The problem is people that say “never do a burnout in first” and we have a large range of levels of experience on here. So I’m pretty new and go into the box with my auto shift 727 sitting in 2nd and think I’m ok because I’m in manual 2nd. No, the car is in first. There are just too many variables to make blanket statements about how to run a 727. Here’s what you do, run a 727 you run a shield or blanket. You also run a billet drum. Then you ask a good trans builder what you should do with the exact equipment you have!
