Orren - Do you have any contacts that could clarify this?
Tom, I had this service performed at W.W.Williams in Hubbard Ohio about 3 years ago, their number is 330-534-1161. I was having the transmission fluid and filters changed as part of scheduled maintenance and Dan (service manager at that time) recommended the conversion to transynd. It was a good 'upgrade' for me.
