2003 Acura MDX -new AT design First sample at 13684 KM 8552 miles Second sample at 50140 KM 31337 miles Wear Check Labs, Ontario, Canada Silicon...8.6/11 Potassium...5.3/4.6 Water...<.1/<.1 Boron...256/233 Barium...14/13 Calcium..365/332 Magnesium..231/209 Moly..0.0/0.3 Sodium..5.1/8.8 Phosphorus..11/10 Sulphur..909/676 Zinc..342/306 Visc @ 40 Deg C..25.5/22 TAN...0.587/0.56 Iron...69/117 Nickel..0.0/0.0 Chromium..0.9/1.3 Titanium..0.0/0.0 Copper...7.4/11 Aluminum..10/25 Tin...0.0/0.0 Lead 1.9/2.9 Silver..0.1/0.0 Wear Check noted increase in Aluminum levels. Their limit is 25. After I took the most recent sample, I noted that I could not easily see through the sample any more. Given ongoing problems with Honda AT's, I'm considering a complete flush of the system with new Honda ATF-Z1 fluid.

The iron is high but the TAN is really low. What if it's normal for Z1 fluid to have aluminum in a VOA? Was the ATF drained & refilled at both sample times? If not, I would drain & refill.

The fluid should be fairly clear. This means the ATF should be changed since it is high in particulates. Too bad we don't have an oxidation percentage.

I would agree with changing this now. Iron is higher than I would like. Seems these Honda transmission produce lots of iron and aluminum. I think a 30,000 mile change is a good interval to stick with.

Had my fluid completely changed today at a Honda Dealer using the Honda Transmission Flushing machine. My Acura dealer did not have a flushing machine!!! I got a really good deal because the Honda Service Tech quoted me $50 Can to do a complete flush including the fluid!! I said "are you sure??? he said yes. When I took it in, the Service Manager said it would be more than this for a flush, but they honored the price quote!! London Honda in London Ontario Canada.

RealWing: Acura has extended the warranty on the AT for 2001-2003 CL/TLs to 7yrs/100k. As other Honda automatics with V6 engines also have more than their share of problems, are you sure yours hasn't been included as well? I understand your concern and your hope that PM can prevent problems, but at least on the TL/CL there's nothing you can do (and switching ATF brands is probably the worst thing, warranty-wise). It just isn't your responsibility, beyond whatever the normal service schedule says...

I missed this post this summer. I wonder what the wear values on pre-03 AT units with transfer case and transimission sharing the same bath. Anyway, compare to my result with one time drain/fill(3.25 qts at 15k),these values are not bad. I believe MDX's manual do recommend ATF service at 30k. Is the shop's flushing machine is similar to Jiffy Lube's T-Tech unit?
