At the track last weekend is when it first became very noticeable. On at least a couple of runs it noticeably overreved/flared going from 2-3. More than one person commented on it, and I aborted one run because it didn't appear that it was ever going to hit 3rd. I let it cool for a decent amount of time and I got third during the next pass. I wrote it off as actomg up b/c it was hot (~200*) and hoped it would go away. You know, a guy's way of dealing with a problem.
A couple days ago I went on a spirited backroads romp and the second or third time I asked it to go into 3rd at WOT it got hung up again. Once again figured it was the heat putting it over the top as it was fast approaching 200*. I went out this evening and ran it while the tranny temp was a relatively cool 180* and it stuck again.
I'm not sure if it would have shifted into third had I waited longer but I just wasn't going to let it sit there basically on the rev limiter. It wasn't bouncing too badly, only minor undulations. The 1-2 shift is perfectly fine and it is behaving normal almost all the rest of the time. The only thing I can even think of other than the 2-3 WOT is that it seems to have a different feel when I am moderately into the gas and cross the stall speed. Sometimes I have the throttle at just the right position, usually in second gear and there is very noticeable lag just under stall speed (approx) and then it kinda takes off when it gets around 4k. This effect *seems* to be more pronounced lately, but maybe it's just me or my driving that's different.
Any help/advice/ideas what is wrong or borken? Thanks
