Broken Transmissions
I spoke with English racing about this and I was told the exact opposite about gear separation.

Straight cut gears a lot stronger but like to seperate under load unlike helical cut gears. So when you put strong straight cut gears in a stock case, the case will give allowing the shafts to seperate which takes out the gears as well.
I have killed second gear or second gear synchro and my latest box is leaking oil. I think the casing has a hairline crack in it. The rear housing had a hairline crack so I welded it up but still leaked so swapped rear section over to a good one and it's still leaking so main housing must be cracked. It's on the top of the casing for reference, it might of had a crack in it when I brought it secondhand but never looked that close at it. I'm thinking about going for PPG dog set but unsure. If I do I will weld bracing on to the case for strengthening. I'm running 455whp at 26psi on a gt30 but it's in the UK so will be a lot more if dynoed in the US. Will be running NOS soon then at Xmas putting a 2.2 crank in the motor and may put a gt35 so I need to find a solution for the box.
I got locked out of 1st gear in my stock AP2 trans. Had ~48k on it, maybe only 3k of those boosted.
Rolled into first while already moving, and as soon as it hit boost, it went right to redline, thought it just spun, and came to a stop, and it never would go back into 1st after that.
Drove it the rest of the season from 2-6th, lol.

I have a stock rear end/axles as well. A few years ago, I bought upgraded bushings, and it seems to really help, I'm hoping that helps keep the flex to a minimum, we will see. I plan on launching this thing now that I have some decent tires on it.
