Thanks Mal

Yes, after you set me on the correct path I did the same thing using the advanced search and got the same result as you. I wonder how many people on the site have twigged to that. Seems like a lot of people - including me! - post questions which have been answered before.

Incidentally, I crawled under the car to check and found the "T" on the diff cover - confirming it's a Twin Traction - but no sign of the final drive ratio. Not that it matters. It purrs along happily in "H" at 60-70mph with the Twin Ultraglide, so I'm not motivated to change it. Around town, I use "D" for jackrabbit starts at the lights. The change up from low to high in "D" is noticeable but not uncomfortable. Just like other two speed automatics of the period.

Cheers

Brian
