So my Fit (2010) takes ATF-Z1. I plan on doing a trans flush here very soon. But as I go to by a bunch of quarts of fluid I find out that Honda discontinued ATF-Z1 and replaced it with ATF-DW1.

Is it ok to replace and flush it with DW1, or should I search for Z1?!?!

Also where do you guys recommend buying trans fluid from?

 

You cannot go wrong with DW-1, it is Honda's approved synthetic blend. No concerns about mixing with the older Z-1 presently in your trans.

Since this is a Honda fluid, you have to buy from a dealer. See how much the online dealers such as site sponsor H and A, or others such as Bernardi or HondaPartsNow would run you...shipping might kill you because fluids are HEAVY so get the complete cost. H and A is west coast, Bernardi is East Coast.

You could also ask if a local dealer could match the online prices. They will often give you a discount if you are armed with a printout of better prices.

 

Has anyone used Mobil synth. gear oil 75W-90 API GL4 or 5 instead?

 

Instead of ATF in an automatic? Don't do it.

 

Thank you, yes I agree. Sorry it did not notice it was the thread for Automatic.
