I have 30,000 miles on Royal Purple Multi Spec. Automatic Transmission Fluid without any problems. I am about to do a fluid change again. Please note you need a scan tool to read ATF temperature for correct fluid level check. I can send you the manual you could follow if you need it. I use their products for every fluid my vechicle requires.
I order it from here. Stock up on all fluids at once since they charge $9.00 fee on all orders.http://www.jegs.com/.../01320/10002/-1
