I always run FULL synthetic in all my vehicles including the transmission and differentials.
Do the Tacomas come factory filled with FULL synthetic? 5W-30?
I will be dumping my transmission gear oil and differential oil the first week I get the truck.
Anyone know if REDLINE MT 90 is the lubricant of choice for the tranny?
Anyone know what REDLINE is used in the differentials?
I know some guys with the 6 spd have switch to MT-90, but the Auto is a sealed system that uses a special Toyota fluid. I'd stick with the Toyota blend at least until your warranty is up.
As for engine oil, there is probably a gazillion threads on what oil to use. Go spend some time reading them until your eyes cross...
I can only speak from experience but as a guy with a right hand that can't grab the shifter, I have noticed a HUGE DIFFERENCE between shifting in my MX-5 and my Yaris. Prior to changing the dino oil I would sometimes need to use my left hand. Not anymore! I know for a fact that it greatly increases ease of shifting.

The Auto is not a sealed system, you can change the oil on it yourself. You are right that the Toyota Automatic Transmissions are designed to work with the new Toyota WS ATF stuff which is already Synthetic. There are no known Third Party replacements for the Toyota WS Fluid as of yet, you have to use the Toyota stuff. You can't use anything other then the Toyota WS Fluid in our Auto Tranny it wont work right and you will probably kill the transmission if you do.
Everything else (i.e. Manual Tranny, Transfer Case, Front and Rear Diffs) uses normal oil. You can replace the Manual Transmission fluid with MT-90 just fine. The biggest difference most people have seen is in the transfer case, most people find it 20 times easier to shift in or out of 4WD when you replace the transfer case oil with high quality 75w-90 Synthetic. The Front and Rear Diff's also use 75w-90 oil and have been known to work better with it. Just remember if you have a Mechanical LSD (Limited Slip Differential) that you will need to add Friction Modifiers into the oil if the oil you buy doesn't already have them, otherwise the LSD wont work properly. Redline 75w-90 already has the Friction Modifiers in it so you don't have to worry about it unless you get Redline 75w-90NS which is the same oil just without the friction modifiers already added. Also adding oil with friction modifiers to a Non-LSD Diff will NOT hurt anything so you don't have to worry if you don't have an LSD.

Maybe a bad choice of words??? But my point is that there is no dipstick, no maintenance schedule (unless you drive in "extreme" driving conditions), and a special fluid requirement that need to be considered when deciding to dump your ATF fluid.
Thanks for the detailed description - I think our points are in-line.

Ah then yes your definition is correct lol

I e-mailed redline for reccomendations on Gear oil for my 4x4 DC, and they recomended MT-90 for the transfer case and the manual transmission. Anyone has any problems with using MT-90 in the transfer case instead of 75w-90?

the auto IS a sealed system. that doesn't mean it is impossible to change the fluid. but it is designed to not be opened. or perhaps you will be kind enough to point out the dipstick for checking the tranny fluid

True that. I was told that it couldn't be changed by the dealer. I personally don't believe that for the life of the truck the atf will never be changed. I just don't know how that will be accomplished. And if Toyota won't do it......then who do you go to?

I guess you are right but I personally don't consider that sealed. The tranny can be opened and you can change the fluid yourself. I don't see how the addition or subtraction of a dipstick all the sudden makes the system sealed or unsealed. A sealed system to me would be there is no possible way to drain or add fluid in the system...ever.

The dealer needs to inspect the fluid on a regular basis, for most transmissions this is 36 months or 30K. Many car owners have already started changing this fluid, the idea that any transmission fluid will never need to be changed perplexes them. See link below for a few ideas as to why the dipstick was removed.
