Royal Purple Racing ATF [color change]

Anyone got an idear on this color change?

3 years since the built trans was put in[TH350], maybe 1000 miles a yr driving if that. Mostly around town and short highway driving to skip around town quicker. I still use the stock in rad cooler with an extra cooler inline after it. Engine coolant temps never go above 200.

tranny was empty when filled.

Ive now noticed a color change in the fluid.

new fluid is on the right, old on the left doesn't smell burnt.

Hard to judge when new RP is nearly clear on the stick or finger, a slight color change is big. Not like reg red ATF that probably wouldn't change a single shade of color by eye if it had that brown tinge in it.

Still kicking my self for not using RedLine

Re: Royal Purple Racing ATF [color change]

Royal purple dye will disappear after use. so dont compare the two colors. That is stated on the RP site.

I dont see anything wrong with the color. You need to smell it as the smell is what you need to judge the condition.
