Thanks for whoever posted to the brickboard to give the tranny a flush. I've had the fluid for a couple of months but needed that extra shuv. One thing I'd try to keep the gallon in sight so it won't overflow. Good idea to put in carton that fluid came in. And I'd like to see an extra 3 quarts go clear too. After 12 quarts it still looked dark. Next time, now that I know I can do it I won't wait so long! Thankx, Brickboard! Thankx, mom! ( She sat at the wheel)!
