excessive transmission noise in 4th gear
 

I'm well aware of the normal transmission/ throw out bearing noise on car and have put in RP to quiet it down. I have noticed that since I've had my car back from the recall that I'm getting quite a bit of noise when the car is in 4th gear. it settles down to normal levels once in 5th. Does anyone else have this problem or know if it's a problem at all? just doesnt seem like it should be any noisier than any other gear.
Also,I have been having some long cranks since the recall, but i think I've read that flash takes a week or 2 to smooth out.

Any help or ideas on this would beg reatly appreciated.

I have a noise in 4th gear, but I don't know where it's coming from. Sounds like intermittent grinding. I've had it for about 20K miles now. Seems to have appeared when my clutch was replaced.
