Transmission problems..... yes or no?

[sr20drft]

Alright, it's been about 6 months driving like this and it has got to stop asap....... I've searched and searched, there are a couple things I have in mind, but just wondering if anyone can help me here.

sr20det redtop tranny and lsd / exedy hyper single clutch kit.

Ok onto the symptoms, sometimes it will grind and pop out of reverse, unless I go into 1st and then into reverse. Often, there is a smack/clunk sound when the clutch is engaged and disengaged quickly. Lastly the most annoying and possibly the worst problems? On deceleration, at around 3k-2k rpm, it chatters like crazy, like to the point where it's louder than my exhaust. Finally, above 3500rpm on acceleration, it also chatters/rattles like crazy, making me not want to push it upwards of 4k+.

One thing I have noticed, it seems like it drives a lot smoother after it has been sitting over night and is cold....... rather odd I think.

So if any of you have any insight to what is going on, please reply, because I'm at the point where I'm about to pick up a new transmission with a much, much softer clutch.

Thanks.
