You might have found out by now that Honda has basically discontinued their ATF-Z1 automatic transmission fluid.

For future automatic transmission use, they've released ATF-DW1.

You might not have realized that the SH-AWD rear differentials ALSO came filled with ATF-Z1 until mid way through the 2010 model year.

All 2011 SH-AWDs come with Honda's new fluid, DPSF, which replaces ATF-Z1 for the rear differential.

While it has a part number similar to Honda's Dual Pump Fluid II (used in the CRV and Element), it is an entirely different fluid.

Retail prices are about the same for all these, typically less than $10 a qt.


Not all your local Acura dealers know this, some of them may want to put DW1 into your diff, others might want to put DPSF into your transmission. If you have your Acura serviced at a Honda dealer, they don't have the DPSF in the Honda lineup, and probably wouldn't think or know to look it up. They cannot use Dual Pump Fluid II, and they might not have any ATF-Z1 left.



the more you know....

 

Thanks for telling us that.

I noticed the change in recommended fluids, but I did not know that it was because ATF-Z1 had been discontinued.

A lot of Acura people get their cars serviced at Honda dealers, so this is important.

Thanks.

 

we keep a lot of acura parts in stock for basic service work, and once something like this changes we are notified on IN just about all honda dealers have access to acuranet as well to keep up to date. this happened a few months ago
