I don't think they are all the same but I wouldn't know for sure. I mail ordered mine and when you give them the make, model and year magically they send you the right one.

I just changed mine for the first time and everbody said
Dextron III. Actually the book listed DexII but I'm not even sure they make that anymore and III is the upgrade.
