They also asked them to work with our engineers on the 9 speed.

Which 9 speed would that be? Cause your current 9 speed is a ZF unit...

ZF 9HP

Note this:
The ZF 9HP is a nine-speed automatic transmission, designed but not built by ZF Friedrichshafen AG subsidiary ZF Getriebe GmbH in Saarbrücken.

Here's a little more reading:
List of Chrysler transmissions.

What part of work with US don't you understand. The ZF 9 speed is a Fiat/Chrysler design as ZF never had a 9 speed before we asked for their help engineering one. It is never ever going in anything other then a Fiat/Chrysler vehicle without the OK from Fiat/Chrysler.

Go screw up a Ford thread DA

In addition, Chrysler needs far more of the transmissions than ZF plans to make. Design choices that make sense for production of 50,000 transmissions a year may not make sense for production of 200,000 per year. To pump out the number of transmissions Chrysler will need, some changes had to be made.

Mr. Kirk said that the partnership with ZF had been mutually productive; while Chrysler owns the intellectual property of any changes they make to the transmissions, they do keep ZF informed. Chrysler can patent any of their changes and methods, including the software and controls, and has some internal motivation to improve the transmissions and their production methods to maintain balance with ZF.

Standards for both manufacturers are high; and both ZF and Chrysler use the same end-of-line test centers, driven by the same software.
