[h2003]

my 03 h2 drives and shifts fine until i get to 40mph cruising around town and it goes into overdrive. when it does the rpms bounce up and down about 300 rpm if i stay at a steady speed. this goes away after 50 mph but its annoying!!! had it at dealer he said he could get it to go away by increasing pump pressure during diagnostic but they are steering me toward a rebuild. i dont know what to do. should i just live with it? thans.
