cooler wanted

That's a strange arrangement. The Rover V-8 auto of the period had the cooler built in to the rad.

Would it be possible to adapt an oil cooler?

Canley Classics might be worth a try -

Ads in the back of Cars & Car Conversions, or Caravan (wrap it in a copy of Dwarves In Very Large Boots when you carry it out of the shop).

It's just an oil cooler - anyone who does car plumbing out to have them handy. I don't think an _engine_ oil cooler is recommended though (wrong sort of size/flow characteristics), although I don't recall the details.

Otherwise a breaker's yard. Lots of big autos have them as standard - see if anyone has a Volvo with a tow hitch on it.

Thinking on this I'm not so sure. Oil pressure in an auto is rather greater than in an engine?

Not much greater though. It's not like the people who've tried to use water radiator parts to make oil coolers, then had a sudden surprise.

I have had a browse around Canley's website, and couldn't find any reference to an auto box, let alone a cooler for it. It couldn't do any harm to give them a ring though, so thanks for the phone number.

I suspect that this is where I might end up. But I have been told of a local auto box specialist, and he might be able to advise on suitable units from other models. I would rather exhaust possibilities for a new or used serviceable one before asking about repairs.

Thanks for the suggestions of adapting an oil cooler, but I am nervous about this option. The cooler is fed from the torque converter, and I don't know if a wrong flow rate might affect the driving or gear change characteristics.

Thanks for the help.

Some Range Rovers used a separate finned tube in front of the rad as a transmission oil cooler. The engine oil cooler was built into the rad.

Try "Think Automotive" they are in Islworth and have a web site, They were very helpfull in a special system I needed

You might try looking at the transmission oil cooler from a range rover or discovery auto. rimmers list them, but I couldn't see a picture.

If you're going down that route, you should be able to obtain an oil cooler to suit from a commercial radiator recon/exchange place. It'll be a standard item, speced by size, but there should be something in thier catalogue near enough the right size.

No - the flow rate will be set by the gearbox in/outs.

You can get aftermarket Auto transmission coolers.

What ever you do in looking and finding such cooler they run in series with the original cooling/temperature control of the auto transmission usually through the radiator. They should have the same flow rate as the original pipes.
