Hi.

I'm looking into buying an external transmission cooler for my A340E.
But I'm not sure what size (inner diameter) the two rubber hoses are that runs from the transmission to the cooler.

3/8 inch? 1/2 inch? 5/8 inch?

Also, some of the trans cooler kit I've seen describe their fittings as 6AN, 8AN, 10AN, etc.

Does 6AN = 3/8 inch,
8AN = 1/2 inch,
10AN = 5/8 inch?

Thanks.

They are 3/8 hoses and you can use the 6AN fittings. I bought the hoses from Driftmotion, Gates 3/8 Push lock hoses.
