Transmission lines

Last year we had a transmission line unclip and lost a ton a fluid on the road. Lucky us, a race car shop owner rescued us and got us going in short order. Just now a transmission line higher up in the engine compartment broke, leaving a huge mess, fortunately just as I parked at our lot. Is this something that Ram's experience?

The lower ones don't have clips like Ford's and Chevy"s according to the race car shop owner. I haven't seen the current line as it's still in the shop .

Just curious... A $350 line this time... sounds like something I could have done but too late now.

Thx for any info.

The line that broke was the block with both lines from the top, side of the engine. I kept the piece and it looked like a small pin hole next to the connection point. It seems pretty strange to me.

    Anyway, I was just wondering if anyone else has had similar problems... I guess not.

    We've been on the road for a week so not much computer time.


    I am on the TDR the original Cummins/RAM forum and have never heard of this problem on a 4th gen RAM.

    Guess you were lucky. ;)

    You will get a lot more input about possible problems by checking out a RAM HD truck forum.

    On the up-side, there’s only 2 trans cooler lines so you got em both replaced now!

    Otherwise, never see them just come un-clipped, I know GMs had some leak prone fittings for several years back in the early 2000s.

    But you haven’t provided enough info to talk specifically to your issue.
    Truck age, rust, etc?
    Both came un hooked?

    The lines are sealed with O rings and kept in place with snap rings. The plastic "cap" must be in place to prevent separation. For some reason lines like to rust under the support brackets. The quality seems to vary as some like to go on forever while others not so much. Be surprised if they gave out before 150000 km.
