There are actually 2 components of "engaging" reverse that people are addressing here. One is just getting the shift lever into the left-most reverse shift plane, and the second is moving the lever forward to do the actual gear engagement. From Saintor's first post, I kind of thought he meant he had trouble pushing the lever forward to get the gear engaged, not so much moving the shifter over to the left. If the problem is the former, and it is not consistent, it's probably a random gear alignment scenario that sometimes occurs going to first as well, and probably nothing wrong. If the issue is getting the shifter to the left gate, I agree mine (10 weeks old) seems to be easier than it first was, or, I am just used to it now. I have noticed though that once in a while I don't quite have the shifter centered in the neutral position and then moving it to the left gate is impossible. Be sure you aren't trying to push a little forward as you push (hard) to the left.
I do think it's a little odd that they just didn't incorporate a pull up or push down mechanism to lock out the reverse gate which then wouldn't necessitate such a difficult pull to the left.
