I regularly have to helicoil gearboxes, but I do all mine when the box is completely stripped so the large amount of swarf can be removed from the box safely.
To helicoil while the engine is in the car is very fiddly especially when you're wielding a drill with a 16.5mm bit on the end, and will introduce ali' swarf into the box ( you'll never get it all out ).
