I am very skeptical of needing a tranny fluid change at 30,000 miles as the honda dealer suggested. We love our Honda Ridgeline, but it was lunging and slipping for a few weeks at 45,000 miles before the (partial) fluid change . I think the solution was a computer reset, not the fluid change. I've never heard of a misbehaving transmission being fixed by changing fluid. In fact I've experienced and heard the opposite: Fluid change resulting is a quick tranny demise. Transmissions, especially Honda transmissions should not be in failure after 45,000 miles of mild driving by my very conservative driving wife. Having owned dozens of cars and working on hundreds more through the years, I smell something fishy.

 

welcome to the forum. if you do not have any factory warranty left on your car, it is up to you if you wish to do any factory advise you don't even have to go to a honda dealership to have your normal maintenance done, your choice as to where you would like to go. some times a reset of the computer will smooth out the transmission, if this does not do it, a fluid change may also help. transmissions should not go out at 45k. should go over 100k. my honda fit has 290k+ but i have had my fluid changed each year. only thing i strongly suggest is to use Honda trans fluid only, any aftermarket fluid will cause trans problems.

 

Welcome in My 2000 Accord had a problem when in reverse, sometimes it would not move even with more exceleration,i had the fluid flushed and it solved the issue.
