Is there an issue using ATF Type T-IV for 2001 Corolla?

I recently did my ATF change on my 2001 Toyota Corolla (4sp auto). In previous times I changed the ATF, I use the recomment Dexron III fluid. However, this time, I purchased online (<a href="http://www.autopartswarehouse.com" target="_blank">www.autopartswarehouse.com</a>) Toyota ATF Type T-IV. I've already put it in my car and have not had any issues thus far. Does anyone know if this specific fluid type will cause any issues with my automatic transmission? Thanks for any insight you can provide.
