What is 'the quirk'?
In SPORT mode, the Pajero NT+ has a quirk that sometimes:
prevents the transmission selecting 2nd gear until above ~3000RPM (30 kph)
downshifts into 1st gear too early (30kph)
The work-around is to simply shift the transmission into DRIVE when below 30 kph.
With additional electronics, a software upgrade, and a modified LED/switch harness which includes an additional harness with OEM connectors, lockup-mate now manages the action of switching between DRIVE and SPORT for you!
