Overview:
This code indicates the transmission is unable to complete a shift across the splitter. The splitter is either stuck in HI or LO, or cannot complete engagement in HI or LO.
Detection:
The transmission attempts the same splitter shift five consecutive times and determines the shift cannot be completed based on the speeds across the back box.
Fallback:
This fault causes a 9-speed fallback and the transmission stays in either LO split or HI split.
