I have a leak in my trans so i have to top off every once in a while. I'm wondering if its bad to use 2 different brands of fluid. Ya know i buy what ever is cheaper deal cause they all end up on the floor.

Stick with the III. It's what the trans was designed for.

At leats go with a name brand like Castrol. I wouldn't stick "Uncle Burts Super A-TEE-EFF" in the trans even if it leaks out in a day or so.
