Leaking Tranny Lines

[BoostN]

Discovered today that my tranny lines are leaking. All 4 are leaking right around the band clamps. I've heard GM doesn't have a fix yet for this. Any info?

Im taking it in tomorrow to the dealer. Only 2,000 miles left on the tranny warranty..

It seems a lot of people have had this issue.

took my truck to the dealer this morning and the lines are leaking they ordered them and they said they will call me when they come in, and they also said they are the new updated lines.

I have heard alot of people complaining about this on their six speed Allison, but mine are not leaking so far.

The dealer had to order my tranny lines along with a new belt for my sqeeking issue. Service writer asked me three times if my truck was at factory height, made me wonder if they was going to give me a problem about it..

Buy a Gatorback from Autozone, it will cure the problem.

These thing are notorious for leaking during the winter months. Mine leaked when the temperatures got into the single digits. The stealer has replaced them under warranty. GM is supposed to have a new design to combat this problem. They looked the same to me hwell:. The P/N's of the three they put on are.

I believe that if they are the arctic lines, they should have an "A" after the part number.

I wasn't able to pull up the P/N with an "A" after it but thats not to say it does not exist. GM would have to have some way to separate the old design from the new. My next set will not be ones from the dealer. Some one will come out with a do it yourself kit to fix another problem could not fix.

I had an '05 LLY and never had a single issue with the trans lines leaking, winter or summer. I bought my '06 LLY on Jan. 5th, and by the 18th of the month, I was back to get 3 of the lines replaced.Hopefully I will make it thru this next winter without problem.

I believe that Mike L from Inglewood is in the process of doing that. I'm sure it will be a quality fix if it comes from him.

What the Hell would that have to do with leaking hoses?
