One last thing, how did you bypass the main rad, make new lines, or just looped it out?

I ran new lines from where the stock line entered the lower fitting on the rad tank to the cooler. Plugged fittings in rad tank to stop coolant leaking out if old tank cooler ever does split. The return line has a coupling close to this point, popped it loose and ran new line from cooler back to that point. BTW- the factory flare on the line makes a great hose barb. Did a similar flare on cut line to the cooler to create a similar hose barb.

Also while still on the subject, I question how much pressure is on those lines (need to do some further pressure checks). I noticed all hose moved back slightly until clamp/hose rested against the barbs with clamps tightened properly. Had I not done the barb/flare thing the line would most likely blew off. Something might be going on here with the pressures and be the underlying cause of the stock tank coolers to split/rupture (shouldn't be that much pressure).

I questioned why only trans cooler splits and not eng. oil cooler. It seems over 1800 T-coolers have been reported under warranty and only 2 known eng. oil cooler failures warrantied. They both are very similar in construction I believe.
