And yet the Super Sprag fails too. Here's a pic of an A&A sprag that failed recently, notice all the pins are straight.

And the kicker, the trans was working "just fine" according to the owner but was pulled because of no Reverse; on disassembly the pan was found to be full of hard debris, further disassembly found the grenaded sprag which took out the roller rear support, rear band drum and the case. If it hadn't been for a broken factory rear servo piston the owner would have attempted another run.

Griner transbrake VB with no LBA and a factory front drum.
