    About 3 years ago I had a trannsmision leak coming from the cooler lines. I had it replace by a local shop. I did everything I could to prevent it from happening agian, it was steel lines and I'm having new drip come from the same line again. I can't find suppliers for stainless lines. The other question is does the 4 speed automatic line work on the 5 speed automatic transmission, mine is the 5 speed. There's one shop in town that makes hydraulic lines for heavy equipment would that be better. I live on the Laurel mountains in PA and have snow, ice and salt problems. My truck is a 2003 F350 diesel, a daily driver if I go any where and a work in progress.

    Which line is it? You may just have to settle for an OEM line again.

    Transmission cooler line - Trans to cooler lines 03 and 04 3C3Z-7R081-CB
    Transmission cooler line - Radiator to cooler line 03 and 04 4C3Z-7C410-CA

    Maybe have it powder coated.

    It's not the cooler lines. I put oil dye in the tranny this morning and drove it around for a little while, parked it till this evening. The fluorescent markings with the black light I've seen so far is on the tunnel right side above the tranny need to look the left side over in the morning.

    It's up at the transmission shop, it's coming from around the torque converter.
