Re: Honda vs. Synthetic Auto Trans fluid
The flush machines should never be used on a Honda, Honda will even void a warranty if one has been used, it's a huge no no.
It's not just Prelude transmissions guys, a lot of late 90's and early 00's Honda's had the same issues as well as the warranties being extended, it was a bad time for Honda's AT's. I work at one, actually see way more Odyssey, Civic and Accord AT's go out than Preludes but then again no one brings Prelude's to the dealer, those along with S2000's are usually pretty poorly maintained.
The engineers know way more than you or any aftermarket company as far as the fluid goes, if your transmission is going to fail then it will fail, if it does best to buy a Honda reman'd unit that has the problems addressed and has a 3yr/36k warranty. Way better than most transmission shops 1 year warranty. The reman'd units are pretty reliable.
