300 TDi 1995 Auto ,gearbox oil cooler

Help advice wanted
Transmission oil leak from pipe to "oil cooler" joint.Bought new pipes .But un-doing old joint from pipe to the oil cooler have stripped the pipe side threads.
What i need is the male/male pipe adapter that fits between the pipes and the oil cooler itself.
Does anyone know where and how i can get hold of a couple .Or do i have to fork out for a new oil cooler ,and if i do will the new oil cooler have these pipe adopters in place ?

Search the web or yellow pages for hydraulic hose and coupling suppliers

cheers will let you know how i get on

this is the part

Found a scrap landy which had the newer round type transmission oil cooler .this fitted Ok just had to re-position a little .
Undoing the pipe union was easy on this type so no complicated pipe joining required . Charge was £25 from scrapyard

And it has lasted all this time to 25 Jan 2018 with absolutely no issues .However i never went through 2 inch thick ice since then .But now rust has overtaken the old bus and old father time is catching me up so its time to say goodbye and send the 300 TDI to the heavenly waiting room (for sale section) in the hope that some parts may be re-incarnated into those most worthy .
