Regular Dexron III automatic transmission fluid or Toyota ATF Type T-IV?

[97&02camryleI4]

97 Camry LE i4 with auto tranny. I already searched but couldn't find any answers. I just need a clarification on which type of transmission/differential oil to use. Both the owner's manual and Haynes says to use Dexron III ATF for the automatic transmission/differential. I have an extra quart of Toyota Type T-IV ATF from a tranny oil change on a 2002 camry. If needed, I will buy enough Type T-IV needed for drain/refill 2 times. Which type is recommended? If I call the dealer, most likely they'll just tell me to buy the Type T-IV since it's more $$ for them. Thanks for the help.

Edit: If it helps, I have 60,200 miles on the tranny. This will be the 2nd time changing the oil. No slips or leaks, except for a suspicous vehicle speed sensor o-ring leak on top of tranny casing.

keep with the dexron3, only use the type 4if you get problems with dexron like some other toyotas like the soarer/cressida etc.

Stay with what your owner's manual states. Use the Dextron 3.
