Owner's manual - DII or Dexron III
Haynes manual - Dexron III ATF

I beg to differ! Differential fluid is MUCH thicker than ATF! Most likely even the old and used fluid in your differential isn't even as thin as the ATF you're about to put in! I suggest otherwise. Differential oil come in 75-90W. My 00' Camry for example, uses Dexron III for it's automatic transaxle fluid. HOWEVER, it uses 75W-90 in the transaxle...
Imagine how bad of a condition your differential would be in with ATF

It'd probably seize within 50miles of running.
