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.

I bought my 2007 3500 dually crew cab 4x4 LBZ used with 53K. They were leaking then. I replaced them at 65K and now have 73K. So far so good. I love my fully decked out rig. This is a minor irritation.

There are a couple of good places to get better lines. Factory non-warranty replacements are just slightly more affordale than getting a divorce.

Sean V. sells his on eBay and I have that set on Chum. 3400PSI hydraulic lines with JIC fittings.

Tony B. has the really nice braided replacements on his site for just over $200.

Unless you can get the dealer replace with late '08+ parts you will leak again. I'm sure Slick will need a new set soon. My only decision will be do I want affordable or good looking.
