My opinion is there's likely debris in the valve body or something mechanically or electronically wrong there. It's also the reason they've told you to flush the transmission. It's also pretty unlikely a flush alone is going to clear anything significant. Not sure if you want to tackle it yourself but personally I would have the valve body removed, torn apart to check for issues with debris and verify the seals, solenoids and wiring connections. The other option is to possibly have Pure send you another valve body and exchange the one you have. This is just one enthusiast's opinion.


PS - Also worth mentioning, you can try temporarily disabling the transfer case and see if the issue goes away. The transfer case SIB describes the procedure in ISTA to disable it for diagnosis.

I’ve been having the issues since I’ve gotten the new trans. Been on email with pure since I got the trans back. It’s gotten much much better since the new trans installation. But it’s still not right.

I’ll look into what u said.
Thank you!
