Well this morning at 5:00am I crank up and pull out on my way to work annnnd, 1st, right into second on a cold car. It has never went into second when the car was cold. I could alway start out in 2nd but never go 1-2. So the XL-18 did something. My fluid history is QS, QDC, Redline MTL, and now QDC with XL-18. We shall see how XL-18 likes 30 degree weather this winter, but for now it IS shifting better.
