I have twin Yanmar 4lha with ZfHurth gear.
I'm looking to replace the non zinc, stock, trans coolers after 3500hrs as preventative maintenance.

looking at these on Ebay that are the right specs as fas as hose and fitting size.

They are the right size specs and have a drain, that I would put a pencil zinc in.
Any opinions? or recommendations for aftermarket trans coolers the won't break the bank??

The stock ones are 600 bucks each and don't have zincs, which is why I am changing them in the first place.
