Much cheaper than most dealers stock (note $8.xx/liter not/quart).
Some would say Dexron III will be fine and it may be, I had it in there for a year and saw no ill effects, others use it exclusivly. But, not worth the risk at the price. Transmission formula is changed over time and is not guaranteed to be compatible with the engineer's original specs.
Now someone can correct me.
