Nothing new, several of the current 6 spd FWD trans used since 07 are joint GM/Ford designed. Such as the trans in a Traverse/Acadia/Enclave.
I had an '07 Acadia that was reprogrammed I think about 5 times by the dealer with shift updates and never did shift right.
It's all a marketing thing... the Joneses have 8 speeds, so the smiths need 9.... then 10...
Once it got over 5 speeds, I think the rest is just marketing BS and makes for a busy and horrible shifting transmission. It also kills reliability to jam all those gears and clutch packs into the relatively same size case. You wind up with smaller and lighter parts. Look at a TR6060, and how small the synchros and blockers are. Put only five gears in that case and everything could be bigger and more durable. 6 speed autos are the same way. Build huge horsepower, better yank out that 6 spd auto and replace with a 3 or 4 speed auto with a much stronger build.
