The other day I decided to venture out in my 04 outback with an automatic without shoveling my driveway. there was about 8 or 10 inches of snow. I made it out just fine. On the way back in I was going slow, and got high centered. I waited a few minutes for the exhaust to melt the snow down, then tried to back out. The car struggled back a few feet, then once the back wheels had made it to the cleared street I thought I'd be fine. they were on no snow, but the front wheels wer spinning and throwing up snow and the car wasn't moving. I revved the engine a little to see if I could dig down through the snow to pavement, and I heard a thunk from the rear and the car backed up. Was this a clutch pakc suddenly engaging or something? Why hadn't it engaged before that?
I've owned two second gen legacies with manuals and have never ever had problems in snow. I've heard the center diff is different between the two transmissions. Is this the reason for my near stuckedness?
What's going on here? Is this normal, or is the 04 not quite working properly?
