Hi Tony, looks like I haven't expressed myself clearly. My car, bought used, had no sign of any transmission service ever being performed. When I drained the fluid, it was quite literally black. I didn't want to do a full flush immediately to avoid "shocking" the old clutch material or mixing up large chunks of sludge. The transmission seemed happy with the increasing amounts of Penrite ATF LV so I did follow yours (and others posted) procedure and did a proper full flush. Thats when the transmission acted funny. I'd assume I followed the procedure properly because the transmission is working perfectly after disconnecting the battery.
