I refuse to use the Maxlife ATF in the rodeo, cause I believe it caused rough shifting a few years back.

However, I have been using the Maxlife in my tacoma, and Castrol Import in the rodeo.

These 2 trucks go roughly the same mileage in between drain/refills, weigh about the same, run the same size tires and overall have the same size engine, etc.

The only difference is the Tacoma has an Aisian warner transmission, and the rodeo has the GM 4L30

Have to say, the last few times I've done drain/refills on both trucks, the castrol atf always comes out still looking pretty new, with a good neutral smell; the Maxlife that comes out of the toy has a brown tint and carries a particular smell...not quite burnt, but just blah, I guess.

Both trucks get changed about every 15k miles, so there's no reason the maxlife should be looking and smelling that way; both trucks are easy driven, no towing, and are only used in 4hi maybe 2-3 times a year.

The only offroading the tacoma sees is the 10 mile *can be wicked* in the winter, dirt road to our house, but I'd say 80% of the time the road is smooth.

Rodeo sees more offroad then the toy does.

Any opinions???....this time the tacoma got a refill of castrol; I see no sense in continuing to buy 2 different types of ATF when one comes out cleaner/fresher then the other.

However...is the aisian warner transmission known for being harder on the fluid?

You will know next time you change it. Exactly which Castrol are you using? I figure with how sensitive these things are to fluid,Ill use what your using,if its working well. Do you add anything to it?

I use Castrol Import Dex 3...no, I do not add anything with it; and I do drain/refills every 15k miles.

Do NOT use the Maxlife in the rodeo, I did that just as a drain/refill a few years back and it started shifting rough in 2-3rd gear; drained and refilled back to Castrol Import and it's been smooth ever since.

I've heard several transmission specialists say to use Dex 3 for as long as it remains available, these older GM transmissions do not like the new Dex 6 fluids, nor should they run synthetic fluids.
