Jon, I've spoken to the owner (Vic Owens) several times (different number). He claims it's a junk yard. Could indeed be both. When I googled it I discovered several business names.
Thank you John, it's interesting that my Jaguar Transmission Service Manual has the exact same photos and band adjustment procedure with the tool yet omits the procedure without the tool. Snug then back off 4 turns. Sounds easy enough. Thanks again.
I have a Jaguar Service Manual that I have read cover to cover (more or less) but did not see the procedure. I would gladly try the instructions you mention and would appreciate a pic of it. Thanks.
