kowalksi, also here on the forums and local to me, suggested it's probably sticky lifters. In the last two weeks I got my upper and lower oil pan gaskets replaced and had the mechanics put in 20w50 oil. I'm thinking it's because I put in the thicker oil as the car has been on 15w40 for the last 4 years from the previous owner.
It's probably my oil. Oh well, it's just damn annoying. lol.
On that note, I had them put in my new oem engine mounts today and wow what a difference. I was running on collapsed engine mounts since I got the car 6 months ago. The front end of the car vibrates a lot less now, sounds a lot better and shifting is even better

. Shifting got smoother after I put in the redline ATF but is not even better after replacing those engine mounts!
