Default So I'm getting a TC, a question about fluid

Thinking of ordering a case of Royal Purple,.. as long as I'm putting in a new verter, From Fuddle.Think I should switch to Royal purple????
I'm not worried about the price, just wondering if its worth it,

no, it's not worth it. i don't think the quality of automatic transmission fluid matters a whole hell of a lot, as long as it's not total garbage and it gets changed when it should, you will get the most out of your transmission.

i use regular aamco fluid that can be found at autozone, i have 10k HARD miles on mine with a full race/high stall shift kit and 5k with my 4k stall (55k total on tranny) and it still works fine...knock on wood.

My best advice would be to see what fuddle recommends in their converters.All fluids are not created equal and may react differently with different clutch material.

Fluid does matter, to the lockup clutch. There are many
different materials out there and they are not all tolerant
of various friction modifiers and degrees of slipperiness.
Get the recommendation from your converter manufacturer
and stick with it. The same would probably be true of any
trans using aftermarket frictions; the stock GM parts are a
known quantity (though I'd be surprised to see GM put their
stamp of approval on funky fluid) and at least there the goo
maker has a sitting target to test against (if they chose).

You can't go wrong with a major brand, DexronIII with the
latest spec anti-chatter additives. This is what you want
to see on the label.

Chuck @ FLT recommended the usual Dexron III for my new trans, says that's what they use in all of theirs.

Aamco or dexron III is what I was told also. Do a search under my name and there was a pretty good thread about all this a few months back.
