spider Posted January 7, 2007 Share Posted January 7, 2007 is there a way to disable AWD when not needed? would this help fuel mileage? Link to comment Share on other sites More sharing options...
bgd73 Posted January 7, 2007 Share Posted January 7, 2007 is there a way to disable AWD when not needed? would this help fuel mileage? all parts are still spinning engaged or not.. if fuel savings happened disengaged, the parts that link 4x4 have a problem. You shouldn't save anything but whatever gets powered getting a break if disengaged. Big letters means yelling, btw. Link to comment Share on other sites More sharing options...

It's been covered many times. Link to comment Share on other sites More sharing options...

Gloyale Posted January 8, 2007 Share Posted January 8, 2007 Actually no. You'll burn the clutchpacks by using the FWD fuse. It's been covered many times. Actually it is the Duty solenoid that gets burned up. In FWD mode it runs at maximum duty cycle. Basically on 95+% of the time. Not good for it, but many people have done it for long stretches. This actually depressurizes and disengages the transfer clutch pack so I can't see how it would burn it? The other clutch packs are unaffected. I wired in a simple switch inside that closes the fuse circuit. However for me this is just to make TCU code output easier. I do not think it would save any gas to drive it like that.

The duty C solenoid by defenition cycles on and off very quickly. It is never fully on or fully off for long periods of time. If you place the fuse in the FWD holder, it signals the TCU to hold the solenoid open, which completly depressurizes the clutch pack. In turn the solenoid over heats and the coil burns up. If you want better gas milage, the only way to do it is by controlling your right foot. These are heavy AWD cars, they do better then SUVS, but worse then their fwd peers. nipper Link to comment Share on other sites More sharing options...
