Re: ZF 9HP48 / Chrysler 948TE 9-Speed

Chrysler realized all of that and THAT'S WHY they went to
outside sources for transmissions instead of trying to
design their own.
The transmission is any carmaker's most expensive component
to design and produce. That's why Ford & GM partnered up
to co-develop the FWD 6-speed they currently share and the
10-speed the new trucks will share.
The new 10-speeds will have a transfer case with only direct
drive and the typical low range will now be handled by the
transmission as the transmission now has an ultra low
forward AND reverse. Actually, it's capable of 3 reverse
gear ratios and 11 forward gear ratios. You can check out
the patent at https://www.google.com/patents/US20140179487
Here's the possible ratios right off the patent: http://autop.ro/9FR
