Problem with transmission cooler lines for the allison transmission. 123,000km's on my 3500 and the transmission lines have been replaced 3 times. 2 times were on warranty and the 3rd i had to pay for myself. i have extended warranty but is not covered, bunch of bs. cost me 850 dollars to fix. should be a recall on them, even the dealer ship says they have lots of problem with the lines. when ever it turns cold they start to leak and have to be changed. *tr
