Transmission for 2000 Toyota Avalon XLS?

Dexron is the correct transmission fluid for your car. If you look at the end of the transmission dip stick, where the level marks are, you will see the mark DEX. This means you should use Dexron.

I personally wouldn't use Dexron in it. Simply because Dexron is meant for GM and Ford Vehicles. It didn't used to be a big deal, but over the years the tolerances have got so close that I would only use Toyota Transmission fluid.

I also have no idea what the difference is between the Import and the regular. Could be viscosity or something like that. In which case it wouldn't harm anything, but you would be getting less protection and the transmission might act a little funny.

My advice would be to use neither and use either a very high quality product like Red line or Royal Purple, or the safest choice (although possibly the most expensive) would be to use Toyota ATF.

Good luck!

ok, yet all over lower back...Lemon rules defend the sources vendors of updated automobiles from extreme, habitual defects. A 6 year historic used motor vehicle isn't secure under lemon criminal rules, and despite if it became, a sub woofer project does not be blanketed. do not confuse the lemon regulation with a insurance. A assure is a promise to repair lined gadgets for the duration of a definite volume of time.
