[SVX10]

Well, after 3 long months of hard work and studying at school in Flint, MI, I had the pleasure of driving my SVX back to Sandia Park, NM...about 1,700 miles. Noticed a few minor things along the way that I would love to fix because they're annoying, but that I hope aren't too serious. First...when I'm below 2,500 RPM in ANY gear (except in first where I can be at any RPM) and I lightly accelerate, the car jerks through the acceleration until it reaches roughly 2,500 RPM. The jerks aren't rough, but they are obvious hesitations every time the car lightly accelerates under the stated RPM. Also, when allowing 4th gear of the tranny to slow the car from say 85 MPH, meaning I just let off the gas rather than brakeing, there is a quiet hum. It sounds kind of like a bearing going bad, but I know it's not because 1) I have 2 brand new rear wheel bearings 2) It only makes noise in the described situation 3) I put it in neutral when I heard the noise and it went away. So, anybody have any ideas on what may be going on? I'm gonna change the ATF tomorrow because it's about that time, so hopefully that will help. If anybody has any suggestions let me know. Thanks
