Max ATF is a synthetic, high-performance, automatic transmission fluid. Its low co-efficient of friction and high film strength help to dramatically reduce heat and wear. Additionally, Max ATF is more oxidation stable than other transmission fluids for longer fluid life.



Who wants to be the guinea pig? Supposed to cross over with Type IV.

 

Nah, I think I'll stick with Dexron Mercon III. It's expensive enough already.

 

I just did a flush not to long ago.

In 20-30k miles I'm going to do a complete flush my droping the pan and replacing the tranny filter with a new one and using Amsoil Tranny Fluid for the first time.

 

How much does it cost? Probably take around 12 qts to do a flush.

 

$10.95 a quart.

I think I am just sticking with Toyota fluid for now and dumping the pan when I do oil changes. Too easy of a job to not drain and fill a couple times a year.

 

I might have tried it down here if they offered it at that price. Royal Purple is available through a few distributors, but they charge you 2x the price in the U.S. for the stuff.

 

Amsoil is probably the best you can buy, and cheaper to boot.

 

If I can find it,Ill try it.I already use royal purple engine oil.And like it very much,rx runs good on it.

They claim it will cross over: http://www.royalpurple.com./transmission-chart.html


Please let us know what you think. I would love to switch to synthetic when my warranty expires.

 

Here's a general price list. Use whatever you wish.

Dexron/Mercon - $1 / quart (cheap, for GM/Ford)
Toyota Type-IV - $4.70 / quart (what I use)
Amsoil - $8 / quart (discount for "independent distributors")
Royal Purple - $10+ / quart (priced to screw royally.)

Not to butt head with the independent distributors or stop their gravy train, though I find the genuine Toyota Type-IV the best for my RX300. 115K miles in harsh Colorado mountains and climate, never a problem. Why experiment snake oil with your $40K vehicle when there's a trustworthy and proven product? Again, use whatever you wish, just gather all the facts first and filter out marketing ploy.

Disclosure: I have no financial incentive with Toyota product.

 

HarrierAWD,

Just curious since we are both at high altitude, how often do you change out your ATF?

Royal Purple charges about 200 pesos per bottle, just under $20 USD here for ATF last time I checked.

 

So far my ATF has been changed at
30K (drain-n-fill by dealer)
60K (drain-n-fill by dealer)
90K (drain-n-fill by dealer, though I suspected the dealer didn't do jack)
95K (3 times myself)
110K (2 times myself)
I plan on doing twice again at 125K.

The ATF level stays constant, so apparently no evaporation issue despite the altitude and low humidity. Are you seeing differently in Mexico City? I live at 6,100 feet, believe M.C. is about 7,700.

 

That is about right on the elevation, higher in areas around the city. Water/coolant tend to have severe evaporation issues here, but I haven't been fully able to ascertain other fluids.....yet.
