I was looking through my myriads of info I have printed off and found an old post from Wally Breer in May, 2004. It's on the trans adjust procedure for a '65 727. I haven't been able to get my trans right yet and this should be the answer. To adjust the '62-'64 you use the rev button whereas with the '65 you use the low button. Maybe I'll have some better luck now with it!!!
After installing the '65 trans in my '64 Polara I never thought about any difference in the adjust procedure. Thank you Wally Breer wherever you are.
