Cracked Transmission Cooler PK Auto
 

Has anyone had a cracked Auto Oil Cooler on their Ranger (2010 75k)?
This happened to me while towing (close to 2.5t) through Central Qld recently.
The RACQ man was on to it straight away, and said it is not uncommon on PKs.
The cooler was sent out to have the crack repaired by welding and seems to be
holding up OK.
Should I completely replace the Cooler or leave it as is ?
Appreciate any opinions. Pm nha khoa
