Well, I know for a fact that Castrol Syntec isn't fully synthetic (but gets to claim it is because it is at least 75% or something like that).
I know Mobil 1 engine oils are fully synthetic. I have previously heard that Mobil 1 ATF and gear lubes were not fully synthetic, but I'm not sure whether this is true or not. I seem to remember that at the time it was supposedly on the product labeling.
However, I trust and respect George and if he says all Mobil 1 products are fully synthetic then I believe him. It is also possible that maybe they weren't at one time but are now, in which case the current product is the one we care about...
Just avoid the 'me too' synthetics. A good synthetic would be Mobil 1 or Royal Purple. A premium synthetic would be AMSOIL, Redline, Motul, or Neo. Beyond that still is the AMSOIL Series 2000 (but there is no Series 2000 ATF).
Regardless, make sure you get synthetic transmission fluid into your tranny. In fact, if someone were to ask me to pick one component on a Tundra for synthetics I'd say the automatic transmission without hesitation.

Mobil makes both mineral based & synthetic ATF, Grease, gear oils. All Mobil 1 products are synthetic. Period.. I do not recall any discussions of Mobil 1 being anything but synthetic.. Highly recommend the Mobil 1 synthetic ATF as it is compatible with the OEM original and is API "Certified" which some of the other full synthetic ATF's are not. If there is ever a warranty issue with Toyota, one is completely safe with the Mobil 1 series as all are API 'certified'...

Fred,
If you don't mind, will you speak to synthetic products versus "Synthetic" products. I do want to change my other lubes at some point and want to go with a good synthetic ATF and lube. I currently use Mobile 1 in the engine but remember members mentioning that Mobile 1 was mostly Dino oil and not Synthetic for the ATF, gear lube and greases. Is that true? Which brands do have true Synthetics? (I know, I know .... AMSOIL ) Others?
Thanks,
Kim

Fred,
Got mine done at the Sullivan Tire in Derry, NH. Was able to bring in my own fluid, but it did cost $75. If I had known about the 2-bucket method then, I probably would have done it myself.

What does the flush machine do that the 2 bucket method doesn't? I think that any process that changes all the fluid in the tranny is what matters.
That said, $50 is cheap because I haven't found a quote less than $100 and several shops said 'we only use our fluid'.
If you use AMSOIL synthetic ATF, it is a lifetime fluid. You can be more than assured that if you did the pan drain and fill every 30K miles (even though unnecessary) your transmission will likely outlast the body...

I just had a complete flush and fill of my Transmission's fluid at the dealer using there flush/fill machine. I purchased my 14 qts. of Mobil 1 ATF from Pep Boys for $90 and the dealer charged me $50 to flush and fill with my fluid through use of their machine. All in all I think this is the best approach since this will get out any particles that might be in the system. I'm sure the 2 bucket trick works just as well but I'd heard from a master mechanic that this method was more effective cleaning out the system. Who knows, all I know is that the transmission seems to shift a little more smoothly than before. I would experience a rough or hard shift from 1st to 2nd sometimes. This has completely gone away now. This truck is worth the $150 or so that it costs to switch to synthetic ATF. I also am using Mobil 1 synthetic oil for the engine. You be the judge for you own vehicle.

I am posting in reference to the full flush.
Has anyone had this procedure done?
How much did it cost for synthetic?
Thanks for the info.

Kev,
I definitely think it is worth it to do he pan change method of your trans to synthetic. I have been doing my Tundra that way. Each time I change the oil & filter I change 4 qts in the trans. Yes, It may take a little longer and cost a little more, but most people probably don't even change their trans fluid until 30k miles, if that.
It is very easy to remove the pan plug, let drain, then re-install the plug. You will need a long funnel with a skinny bottom to fit into the trans dipstick tube. I put a towel below the opening of the tube, hold the funnel in place and slowly pour in the trans fluid. (4qts)
Some one posted the calculation here a
while back, and in about 7-9 pan changes your trans will be over 90% synthetic. That should be more than adequate.
As for the transfer case and diffs, go ahead and change those too.
Good Luck,
Jeff

If you want synthetic in your tranny, I suggest you do a full change-over rather than 4 qts at a time. Doing 4 qts at a time will take a long time to get to a 100% synthetic state.
Easiest method for a complete switch over is the "two-bucket" method mentioned on the old site.

Full flush and fill is 13-14 qts. Just a pan drain and fill is 4 qts.

I remember other TS members who replaced their ATF said it took 3.5 to 4 qts. and not 2.1 qts.
