ATF Cooler coolant lines?
 

Having ordered and received all new heater hoses (4) and getting ready to do the job I notices there are two coolant lines to the Automatic Transmission Cooler (2001 3.0L).

I rebuilt the cooling system a year ago with new everything except radiator and expansion tank. I did not replace the heater hoses at that time because they were soft, supple and the O-rings looked and felt in good condition.

Recently I replaced the Y Duct in the intake system and in the process must have upset the O ring to the heater hose coming out of the expansion tank and now the fitting is leaking so I decided to replace all the heater hoses.

Now I find the 2 coolant lines for the ATF cooler.

My question is: Has anyone had a problem with these hoses leaking?

I hate to wait another week for hoses so I am going ahead with the heater hoses which will fix my present leak and hopefully prevent others in the future, but what about those other 2 coolant hoses?

Any advice would be appreciated.
