Going to change my M6 tranny fluid this spring. Anyone have any negative effects using the Honda fluid?

As a second alternative, what is a good brand to use for normal Dextron III ATF fluid?

Thanks for you input.

 

i use that stuff..call me crazy but i think it actually made a difference in the feel of my shifter.

 

I've used the Honda ATF for over a year and it still shifts precisely w/o any extra noise.

 

Well it made the tranny noticably more notchy when its cold out (<50F). Until it warms up its much harder to shift into 1st or 2nd unless you come to complete stop.

Of course its normal for it to feel a little different when cold out but I dont recall it being this bad with the M1 ATF I had in there previously.

FWIW I plan on changing mine as soon as I can find something that is proven to be better. I'm considering some Redline D4 ATF right now...

 

I have the Honda ATF in mine, shifting feels great. I would do some research on here before using the Synthetic stuff. Supposedly the synthetic doesn't produce enough friction for the syncros.

 

I use Honda ATF and its good stuff. I will say this though....I was using Mobil 1 ATF before the switch and noticed no difference in feel and slightly more noise. I plan on going back to Mobil 1 next time I change it.

 

Nothing wrong with the regular stuff IMHO.

I am using the Honda ATF in mine like someone else said cold its alittle notchey but after it warms up shifts fine nice and smooth.

Anybody tried the royal purple synthetic?

 

i also use the honda atf z1

 

I am still not sure. I haven't driven my car since November. I can't remember how "notchy" the tranny was before. I might just try some quality regular stuff for now. It's got to be better than the old fluid in there now. Thanks for the replys.

 

Interesting..... I know some guys that race hondas/acuras and all of them use GM syncromesh trans fluid. I have never heard of anybody not liking syncromesh. Plus you can probably get it from www.gmpartsdirect.com for cheap or buy it at your local dealer.

I thought I read in my search that you should not use GM synchromesh in the T-56. I could be wrong though. I haven't researched it, but I didn't think it was ATF fluid like required. Any input?

I am probably just splitting hairs about all of this tranny fluid stuff anyways.

 

I use Mercedes Benz tranny fluid. Not because its better but because I can get it for free at work. It didn't make any difference to the way my car shifts gears. So long as its proper tranny fluid you are using I don't see how one brand would be better than another, atleast for an M6. Tranny fluid is tranny fluid.

 

I'm running the Royal Purple product line from front to rear....Very pleased with their synthetic oil's
