So I live in the mountains and it snows A LOT, well not last year but usually. We got 4 inches last night and with any luck we won't see blacktop until late April. I had a 2000 XJ for last 10 years and I pretty much put it in 4H in November and left it there until spring thaw, unless I went down the mountain to Denver for any reason. This is my first winter with my 07 JKU and I've heard a few people say 4H puts too much stress on the JK transmission, one guy even said he burnt his transmission out after only 20k running in 4H too much. Is this the case, should I use 4H only sparingly? I drive 30 miles roundtrip each day, plus sales calls, on mostly snow covered roads. My commute will always consist of some pavement, snow and black ice. Can I just leave it in 4H or should I be weary of that?
