automatic transmission

Fluid replaced how about the filter? To me its still slipping and need further diagnoisis to get to what's causing it to slipped-Could be a throttle position and vehicle speed sensor problem if its not coming from the transmission-these sensors are use to indicate throttle and governor pressures

I have an 07 now and we have 3 other Odysseys in the family. I was wondering if you have ever had the trans flushed, not just drained and refilled. Flush costs about $90 where I am. I've heard 2 experts say the Honda specifically because its known to be weak in the trans, and other cars too should have the flush every 30000 mi. I've only got 20000 on mine so far.
