cars -- who the heck knows what was done to them before I owned them. I changed the fluid before detecting problems -- most likely trans was at the end of the line anyway -- coincidence?? 3) The 06 Odyssey -- that darn torque converter seems to go bad for everyone -- its worse every day, having trans fluid changed today with false hopes the problem lessens. I guess my personal dilemma is one of trust vs time. Its hard to find a mechanic you trust.....sometimes you may trust the head guy but he's not the one working on the auto. Doing it myself....learning curve...Exxon Valdez in Driveway. Thus ignoring the issue until there is a problem, creating an even larger problem! The other factor is paying dealer vs doing it yourself. A rebuild may be less expensive than paying for 5 trans fluid changes (each 30k over 150k miles)unless you DIY -- in this case -- also Let 'er ride! Excellent topic for discussion since the automatic transmission is sometimes viewed a mysterious sealed unit which only the Hogwarts kids can conjour up spells to fix. The advice I was recently given from an Aamco owner who services all of my cars was "here [in Pittsburgh] you have extreme heat and extreme cold, the fluid in the pan [of a car] should be changed in no less than 25,000 miles"
