Transmission fluid evolution..

[falconbrother]

My old burb was designed for Dex III. I have of course been using Dex-6 on the occasional drain and fill. I went to the store to buy some Dex 6 the other day and all they had was a synthetic Dex-6/Merc-LV. I read the label and it reads like a fluid that replaces the above two plus some import fluids. I suppose I will run it and not worry about it. But, as a general rule, I haven't been a big fan of the multi use fluids.

They sure do...even the brand new Accord can be had with a 6sp.

Hard to wrap my head around, but Toyota has been using 0w-16 on its Japanese vehicles for 2 decades. Guess we'll see how it plays out, especially driving in Florida in the summer months.

Our 2014 Honda Accord specifies 0W-20. I use Mobile One Synthetic 0W-20.

Same here with the Mobil One full synthetic. I don't trust Honda manual transmission fluid, so after breaking the car in, I immediately dumped the factory gear fluid and put in Penzoil Synchromesh gear fluid, and the shifts are smoother, and the engine revs more freely.

The Civic SI is manual transmission only.

I understand your aprehension on a multi use fluid.
A couple I have had good luck with are Valvoline Maxlife atf, and Amsoil.
The Valvoline Maxlife is a newer formulation that is similar to the low viscosity formulas like Dex6 and Mercon LV. It still seems to work fine in the older Dex3 applications.
Amsoil handles it a bit different, they offer a low viscosity formula and a traditional viscosity formula. I do prefer this, since you csn more closely match the viscosity to what the transmission was originally designed to use.

On my tundra i just did my first transmission service . Drained 4 qt out and out 4 qt in at 140k. Mine is a full sync world ATF and it is suppose to be lifetime. i plan to do it another one in 60k.

Initially, on the CRV, I bought Honda transmission fluid. Then I started using Casterol import synthetic transmission fluid (Transmax). I rode on that for a few years. It did perfect. I do know that Toyota transmission fluid is top shelf stuff.

My wife's town and country and my old CRV have "sealed transmissions". On the van I pulled the pan and changed the filter and filled it back up with ATF+4. 159,000 and shifts like it did when new. On my old CRV the transmission doesn't have a pan but it does have a drain plug. About once a year for years I have drained off three quarts and added three quarts. 200,000 miles later still shifts perfectly. There is no such thing as transmission fluid that never wears out. Cars and trucks are designed to be very low maintenance but, need a major repair every 150,000 to 200,000 miles.

probably does not matter at this point but dex 6 was not backwards compatible with dex 3 at least not in the Allison transmissions dex 6 would damage the seals for some reason there was a certain manufacturer date for the change over, look for the material standard number if it is on the bottle it should be ok .

Dex6 if fully compatible with GM transmissions using DexIII. Your correct on certain allisons, but it's an allison not GM transmission.

And I believe Dex6 has always been a synthetic fluid. but only more recently labeled as such by many aftermarket suppliers.

Personally I'd get a Dex6 fluid, not one designed for multiple uses. See if it says "compatible with" or "GM approved".
you want one with a GM approval

Lubricants continue to improve on regular basis. It is one of the reasons cars go 200,000 miles now and often much longer.
