4EAT rear clutchpack lock for 4wd instead of AWD

you all know you can lock the rear clutchpack in your 4eat to make it essentially 4wd instead of AWD, right?

there is a connector coming from the transmission... should be 16 pin connector.. 4 rows of 4 pins.. resistance between pins 4 and 11 should be around 13 ... cut the wire going to pin 11 from the tranny (usually brown) and put in a switch so that you can "switch off" this wire...

with wire disconnected, duty solenoid C locks rear clutchpacks and you're in 4wd

with wire connected, duty solenoid C allows rear clutchpacks to vary power split, or this is my limited understanding..

I and others at ultimatesubaru.net have done this mod, and it does work

That's basically locking duty solenoid C in the on position. I can't imagine it would be too good for the clutchpacks.

but if they are locked(not slipping), wouldnt they have no wear?

When you cut that wire, you have a short circuit. The duty c solenoid is NOT on at all. It has zero current going through it.

If you do this on dry pavement, you will more then likely kill the rear clutch packs and or the transmission prematurely.

Even in snow or gravel, I'm not sure I'd recommend it. You'd "probably" be fine, but I can't comment on any long term affects it will have on the transmission.

guy from xt6.net has been doing this for over a year on his XT6 4eat ... I'm sure my engine will go before the dying transmission
