    Good!!!! I can't stress enough how serious your problem is. You may have already lunched your trans. Once the oil is gone you can go maybe 300 miles before the little sounds start, then the heat, then the crunch and your done.

    I have to replace my line as well. I think my fittings where each line connects to transmission are facing the ground on the bottom of the tranny. If I pull the lines off to take somewhere to get made will all the oil drain out? Also, does anyone know what size the fittings and thread pitch are? Maybe I can get a short coupler hose like mentioned earlier to hold me over until I can get the lines made.

    Had I known what I know now Id have changed the trans oil/water heat exchanger to an air cooled one.
    I still want to do that as Its too risky losing a transmission. Granted that heat exchanger lasted 12 years and that's quite a long time but one day they will fail and get water into your transmission.

    I would have looped the oil line together and looped the water line together and not spent 600 bucks on a new cooler.

    Mine went bad a couple months ago and I didn't know it until I had water pouring out the input shaft port onto the ground. There's no seal there so coolant just pours out around the input shaft.
    What that did was ruin my synchroniser. Now I have a noisy Low to High shift after changing the oil twice.

    It needs switching to air cooled trans cooler where a raditator is bolted onto the frame somewhere or by passed looping oil to oil and water to water.
