Automatic transmission fluid.

This is probably a rediculously easy question to answer, but I finished up totally confused.

Borg Warner AS1-35TA auto box, as fitted to a Wolseley Six. Suitable fluids are listed as Castrol TQ, Sternol Lynx Type A, Mobil ATF 200, BP ATF Type A suffix A, Shell Donax T6 and Duckhams Nolmatic. None of these seem to exist anymore, so what would the current fluid be?

P45.

I went through this with my old 18/85 five or so years ago. Same or similar Borg Warner 35 gearbox driven by chain

This thread is worth a read and explains the difference in supporting an original rather than a rebuilt gearbox.

What we do have on this forum is a gearbox expert in the name of Harvey. Over to Harvey!

Use fluid that meets Ford specification M2C-33F, or G

Dead right, Ben.

Thank you very much, Harvey.

Nothing to do with oil, but Bent8 mentioned a chain drive autobox. Is that what these are? the internals of a BW35 slung under the engine and driven by chain? Wow!

This is the unit fitted to the 18/85.

It helped make the whole lot very easy to ground out. As I found on a couple of occasions.

Chain driving gearboxes isn't so obscure on US front-drive cars such as Cadillacs and Oldsmobiles

 

[Wikipedia entry explains better]  The 1966 Oldsmobile Toronado (along with its sister models the Cadillac Eldorado and Buick Riviera) used a novel arrangement which had the engine and transmission in a 'side-by-side' arrangement with power being transmitted between the two via a heavy-duty chain, and a specially designed intermediate driveshaft that passed under the engine sump. This family has the distinction of being the highest engine capacity (8.2 L) front-wheel-drive vehicles ever built. The Saab 99 and “classic” Saab 900 also used a similar arrangement. The Eagle Premier used a similar powertrain arrangement found in the Renault 21 and 25 – later becoming the basis for the Chrysler LH sedans produced until the 2004 model year.
