I am under the impression that Aisin (Toyota?) and BorgWarner (GM?) make more reliable automatic transmission than their competitors (i.e. Honda, ZF, Chrysler). This seems to be at least the common perception in the last couple decades.

I would imagine patents that old are expired and they should be able to all make reliable transmission for a long time by now.

who actually wants a 4sp?

5,6,7,8,9 speeds are where it is @; not.

Two coworkers bought Skyactiv Mazda 3s with a 6sp; one transmission has failed under warranty, the other takes 10 seconds to shift into reverse; dealer says "no issue".... yaaaaaah.

GM doesn't own BW. Tremec/BW transmissions are used in a variety of makes including Ford and Chrysler.

Aisin is 30% owned by Toyota.

GM makes their own automatic transmissions, just like Ford. Hence GM Powertrain.

They know how to make a reliable transmission-- they just choose to make them smooth shifting with a zillion speeds and variable lockup and 400 lbs/ft of torque going in while sitting sideways in a minivan.

Didn't the Chevette 4 speed TH200C wind up in full size Olds Cutlasses?

The coolest thing to happen reliability wise IMO is cutting engine power during shifts.

I agree

Quality improvements are subject to the competing factors of; organizational structures, personalities, employees / teams / managers, budgets, priorities, management dictates, corporate learning, culture etc etc. Just look at the GM ignition key debacle.

What should happen and what seems obvious, sometimes doesn't. Ultimately it's a management failure though.

Of course GM and Ford have been collaborating on transmissions.

GM and Ford have been collaborating on automatic transmissions since 2002. Interesting read: http://autoweek.com/article/car-news/ford-gm-work-together-new-nine-10-speed-transmissions

True. No real issues with the 6F550 in the SHO - 78k and it still snaps off shifts like the day it was born. smile I've driven some 6F's in the Fusion and other than a harsh 1-2, at 60-somethingK in a rental it still shifted fine. You don't hear too many complaints about the 6F behind the Edge, Flex, Explorer, and Taurus either.

They do weird things - but so do others.
