Transmission Oil Question!

I need to change my transmission oil. I did some reasearch and found a tutorial online, it suggested that I use 75W90 GL-4. I went to both Cdn Tire, and Part Source today looking for either Royal Purple or Red Line Manual tranny fluid. Neither place had either. Does anyone know where I can get this? Or if is there something better you’d recommend?

i use royal purple 75w90, i like it… i got it from performance improvements on the queensway.
