Question?

[ROYT]

Can anyone tell me the difference between Dexron 2 and Dexron 3??

What are the specs?

I think it's to do with the range of operating temperatures, with Dexron III being more tolerant in this respect. It might be best to look on one of the GM forums in the US for the definitive answer.

Just in case you were wondering however, fluids pertaining to GM Dexron or Ford Mercon specification are NOT compatible with the LS400 transmission, regardless of what anyone tells you. Including the Toyota or Lexus dealer. You MUST only use Toyota Type IV , even if the parts guy looks at you like you've got two heads or claims he's never heard of it.

It's OK to use Dexron in the PAS pump.
