Recently told me to use Castrol Transmax Import, for what its worth.

You can use whatever you want, technically. But it will make a difference what you use. If you want it to perform how it did from the factory, you should use Dexron III or Toyota T-III. That's what it's designed to use. Personally I highly suspect any All-In-One type fluids. Since OEMs don't use or recommend them.

It's funny your ASE buddy didn't mention these things, or why you should use what. Shows what he knows I guess.

Also be aware that if your truck has not had regular service on the transmission, you might create a problem vs preventing one. For example, a transmission with 120K miles that has not had regular service, could either die, have issues or be ok. Basic rule, if you have high miles on a transmission and it is still working ok, do not mess with it.

It was designed to be used with Dexron III ?

My FSM says Dexron II, I don't know if its a legit Toyota FSM though.
So I asked him what I would use because you won't find Dexron II anywhere. So he responded with my aforementioned fluid.

Yeah thought it was II. But II was replaced with III I believe. And there's dexron/mercon that says it's a suitable replacement for III. Doing a fluid change myself, concerned that when I drain the fluids that of course it won't be completely drained, so does the new stuff mix with the old stuff well?? Who knows I'm confused.

The original fluid was Dexron II, which was later superceded by Dexron III. Manufacturing licenses to produce Dexron III expired about 10 years ago. Companies are still manufacturing Dexron III type fluids, however they are not allowed to call them Dexron III since they don't have a license. You will often find these fluids called "Dex/Merc".

I have used Castrol Transmax Dex/Merc for the past several years in my older vehicles that call for a Dex II or Dex III fluid. It meets the specifications and is easy to find.

The msds shows it to be a Dex II/III fluid.

Good info, thanks for clearing some things up.

Working on it now. FSM says to use fipg gasket maker, I have that but I also have a cork gasket that came with the trans filter. Using the fipg seems like it will be tricky to get the pan back together with the driveshaft partially in the way and also laying on my back trying to line everything up. Cork gasket seems like a much easier install, not sure how it will hold up. I'm torn, any advice?

I've always used a gasket, never had any leaks. I prefer the gasket because it saves me from having to scrape all the FIPG off the mating surfaces the next time I remove the pan.
