Well just got back from about 50 miles of driving/playing.
The tranny shifts very nice and even now....now harsh clunking or banging into gear, dowwnshifts are just right and it has nice manners now.
The shifts are firm but not harsh. I was at first surprised that it didnt lurch into gear etc....maybe thinking it should be firmer with the shift kit. But I thinks its pretty good, far as I can tell.
I tried a number of times to make it double-bump and so far so good. Will try and get more drive time in and see for sure......I think if it was going to do it, it would have already.....but its only 55/60 out and I think it was heat related in part....but keeping my fingers crossed.
But man, its so much nicer to drive around town now!
