Thanks aaronm, my 2002 is at the shop as we speak. It just started to slip into 3rd. 243,000 plus km and I am happy that it lasted so long. The tranny builder is using Dexron and I justed wanted some opinions on this. Unfortunately I can't find Valvoline Maxlife in Toronto and Dexron is easy to find.
I've used Valvoline MaxLife DexMerc for many thousands of miles with no problems. Good driveability, not expensive, so I was doing a drain/refill with each oil change. The only reason I stopped using it was that it became very difficult to find in my 4x4 town (not four wheel drive, but 4 miles by 4 miles in size). Have no idea why WalMart stopped carrying it, as it was a very strong seller.
funfinder4 and MTPockets80 have also used it with good results. I've got AmSOil ATF in both Odys right now having done 2 drain/refills, and the third one coming up soon. I can tell no real difference between the ATF-Z1 and the other high quality products, other than it feels like the shifts are slightly "crisper" (firmer?) in a proper way when using the MaxLife or AmSOil products.
Just had my transmission rebuilt at 150k. Shop prefers Dextron instead of Honda fluid in our older vehicles. I double checked with another transmission shop and got the same answer. Honda fluid is superior in newer models.
