It wasn't that dirty but wasn't clogged. It was the original fluid and had never been touched. Right now with about 24K miles on the car since doing the flush I couldn't be happier with the performance of the transmission.
Before doing the flush the transmission would take about a second to a second and a half to engage in gear when moving the shifter. P to R would take a second to second and a half to engage. I would move the shifter from R to D and the same hesitation would occur before engaging. Immediately after doing the flush the engagement was instantaneous.
The jumping in and out of OD was when I was going up a grade. It was as I felt down shifting earlier then when I thought it should. After about 1,500 miles it stopped doing it and now holds the OD longer during a hill climb before dropping down a gear.
