Changing couplings/lines.everything to new radiator. Prices at Advanced not bad. Lines were pretty rusted towards rear so having to replace them is not a bad thing and will give me peace of mind. I will update you on how it goes. Thanks.

 

 

Yep, I'd be interested in how this went too!
My trans cooler lines are weeping at the lower joints and I'm wondering whether I should replace the couplings and if so, what with.

 

The illustration in post #9 shows all the parts you need.

 

Thanks, CCKEN.
Just finished up job tonight. Trans lines and fittings were a perfect fit. I have a little seepage at the flare line at radiatior. It was dripping when I first started vehicle. Tightened but may need to snug some more. Ordered lines from Advanced and they had them to me in 3 days. I will run Jeep for a few days just to keep an eye on things. Then turn it back over to my daughter. Glad the job is done. Thanks again.MRRYDER

 

I just did this job replacing both lines and the fittings.

I found the front pressure line was broken at the transmission fitting, and the rear one was just a mess with rust. Replaced both lines, the transmission fittings and while I was at it, I tossed in a new radiator...

All parts bought on Rockauto... it was about $22 for each line, $7 for the Dorman fittings on the tranny... and $85 for a new exact fit radiator.

I realize not everyone would go my direction, but everything I replaced needed to be replaced... even the radiator. Great peace of mind knowing everything under me is new, rust free and tight.

Hardest part was pushing in the lines to the Dorman fittings at the tranny.

 

Good work.

Just make sure the trans fluid level is serviced to full.
