2010 TRD OFF-ROAD 4WD DC with 9 drive modes (using VSC Off, A-TRAC & RR Diff Lock switches): 1) 2WD: VSC and TRAC active, 'Vehicle Stability Contro'l and 'Traction Control' (Limited Slip Diff.). 2) 2WD: Switch turns off 'TRAC' and 'VSC', and turns on 'AUTO LSD'. Gives maximum power to tire with traction by braking spinning tire, without cutting power. 3) 2WD: 3 second push of switch turns off VSC, TRAC & AUTO LSD for open differential. 4) 4WD-Hi: VSC and TRAC are both on. No engine power is cut in TRAC while in H4. 5) 4WD-Hi: 3 second push of switch turns off VSC and TRAC. 6) 4WD-Lo: VSC and TRAC are off (open differentials). 7) 4WD-Lo: Push of A-TRAC button activates A-TRAC (Locker-like limited slip). 8) 4WD-Lo: Push of RR DIFF LOCK switch to lock rear differential. 9) 4WD-Lo: RR DIFF LOCK and A-TRAC combined. 5 MPH limit. |
You have 3.73:1 gearing. Only the 6 lug 4 cylinder models come with 4.10:1
