I've had some problems with shifting from D to R and vise versa, also surging when going down a slight hill between 7 and 11 MPH. Took it to the Honda dealer, they checked the oil pressure at the test ports and said the trans oil pressure was low and the engin oil pressure was high, tha most likely a piese of a clutch disk partical was cought in an oil passage way, and the only way to fix it was to split the case at a a cost of $2,000 dollars for 17 hours work. I asked could they back flush it, the responce I gought was no one had ever asked that and they had no idea if it could be done. So now my question to the form is has any one ever back flushed the engin and or any ideas how?
