How many of you have leaking allison trans. Lines?

I already asked about leaking trans lines on the allisons, but this thread I would like all the members that have had, seen or heard of people that have had the same problem as me to post a reply stating exactly that. I.E. how many times, how many miles, If they took care of you etc. Reason being, I want to copy it and submit it to GM. these are supposed to be a quality truck, but if you continue to use the cheapest supplier for manufacturing, why should the consumer have to pay for it in the end. I think $45,000 + for a truck is paying for quality up front. If you can't get 100,000 out of trans lines under normal conditions, then I see a problem.
thanks

Mine "seeped", not really ever leaked. Even with a slight seepage, they were replaced under warranty about 20,000 miles ago and seem to be just fine. Service manager commented that they were a "b!tch to do correctly".

I think they are difficult for some green mechanics to install correctly.

I had one replaced just about 2 weeks ago. I am working on a fix for my lines now. A guy over on DP replaced the lines with Aeroquip line and fittings. When it gets a bit warmer out that is what I am going to work on.
