Trans shifting oddly

For the last few weeks, my trans has been occasionally flaring about 100 RPM when shifting to OD. It only does it at light throttle, and one out of 20 times. When I hook the trailer to my truck, it's fine. Very strange. No CE or trans lights and my fluid/pan looked good when I did my valvebody Saturday.

I figured upping the pressure with the VB would help? Is this an electronic or mechanical issue?

Thanks in advance,
Marcus

I know my tranny was shifting funny when my MAF got dirty.

Which valve body did you use?
