That exactly the same thing @Frederic was explaining ‘upshift issues’.
when in manual mode car automatically upshifts to next gear upon reaching desired RPM and we looses all of sudden power while climbing a dune .
Models after 2011 doesn't has this problem. RPM reaches to 6500 without any issues and no issues of upshifting.
And i will never support Omani Hack as it transforms vehicle into safe mode restraining many things. Never ever use 4LLc other than recoveries if you don't want to kill transmission.
i am one of the victim.
