If you got all new bolts I could see maybe getting some old ones mixed in with the new and ended up putting a starter bolt (they are much longer) in that hole. You may have gotten 37lbs-ft on it but that’s because it’s bottomed out in the hole and not actually torqued on the head like it should. The tranny was engineered to have ALL those bolts for a reason. It’s not going to fall off but I could see the extra load on the other bolts causing them to back out at some point. I would remove that bolt and compare the length with your old bolts and if it’s longer then you found your problem. If it isn’t longer then you have something stuck in that hole or you managed to cross thread that bolt (which would be really hard if not impossible).
