I want to DIY flush my 2001 Accord automatic transmission by disconnect a line from the cooler ( which one is best ? - how to indentify ? ) and best procedure ? . Also from what I had read , it is preferable to stick with the pricey Honda Brand ATF vs Dexron III with Lubegard " conversion " additive ( I wonder since the other lubegard stuff has work great for on non-"conversion" applications .
