Transmission Cooler Lines Leaking

My transmission cooler lines are leaking right where these metal crimp connectors are. I read somewhere else that this is 3/8 transmission hose line but I am not positive. What is the best way to go about fixing this problem?

I was thinking of just buying some new 3/8 line and connecting them on with hose clamps. Will this work fine or will I have some problems doing this?

Also, where the line connects to the radiator there is a cheap plastic snap connector located on the copper fitting on the radiator. I had this pop off on me the other day and there was literally a river of blood running down my driveway.

The auto parts store did not carry 3/8 line so it looks like I have to order what I need online. Any suggestions on the best way to solve my problem?

Thanks!

Here are the pics.

Rockauto.com carries both replacement lines, shouldn't run you more than $50 for the pair. You may need to source an adapter for the transmission side of one of the lines, but it should be fairly easy to find at a local auto parts store. It's about a 30 minute job to replace both.

Ok Thanks. I see the replacement trans cooler hose on rockauto but I am not sure if thats all I need to solve my problem? You said there are two lines that I need?

Buying 4.5 feet of cooler line hose should be all I need correct?

Like I said, you can replace both lines from the trans cooler all the way back to the transmission for right around $50.

There are plenty of people who cut out the section you have pictured and replace it with transmission cooler line and use hose clamps. So that is an option for you as well.

Around here, quality Gates transmission cooler line is $5 a foot, so at four feet, that's $20, plus the costs of hose clamps. By the time I walk out the parts store, it would cost me $30 to repair it that way.

For me it was worth the extra money to repair it using an OE style part and get another 15 years of service out of it.
