Re: Trans cooler questions....

There is one thing to keep in mind if you change lower radiator hoses. The oil coolers used thin steel tubing for their hose connections instead of the brass tube the radiators used. Many have found the ends on those oil cooler pieces rusted severely -- to the point of disturbing them to remove the hose sometimes takes a good portion of the tube along with the hose. Just something to be aware of.

It's one of those catch-22 situations. If it is not causing a problem do you leave it and then have it fail next week or do you change the hose and then have to fix or find a new cooler in a hurry before the car can leave the shop.

If you do change the hoses and find an issue, several have had the tubing replaced at a radiator shop. I believe ordinary exhaust tubing was generally found to be similar to the original.

NOS units are getting scarce and guaranteed good used is dependent on the supplier as to how good. Some "good used" have been found to just have had the rust spots filled with bondo and painted. The tubing was paper thin underneath.
