Haven't seen any post lately concerning crip joint leaks during cold weather. I think GM is recognizing that there is a problem with the 2008 6 speed tranmission cooler lines. Will have more definitive info later this week.:thumb

Had leak in one line Feb 14. Purchased a repair kit from Alligator Performance and had my local Chevy dealer put them on for me. Received ltr from GM dtd Jan 2015 with extended coverage for repair cost to cover labor and one line
replacement.

"GM is covering 2008 Silverado & GMC Serria with 6 speed trannys 10 years or 150,000 miles. Anyone that has had repairs done (not sure if by GM or not) needs to contact GM with documentation if you have not received a letter.

I have already received my reimbursement check. You could have knocked me over with a feather. Flabbergasted to say the least!!! :gearjamin.

They know they have an issue, I just got a letter from them telling me that they are covered for 150k, too bad I'm at 180k.

Tranny Fluid Lines

The leaks normally occur during extremely cold weather at the crimp joints. Check the surface under you vehicle for leaks. 10 years or 150k miles, whichever comes first.
To be sure that GM will honor the repair, go to your Chevy Dealer if you have a leak. Not sure they will reimburse you if you do otherwise. They did reimburse me the cost of one line and installation cost. Check with you local Chevy dealer to see what the deal would be for you. My dealer installed the after market kit for me (3 three lines) and it looks like I got credit for all the labor charge and the GM cost of one line. I'm just blown away. I have not had any problems with the lines for a year now. Looks like my dealer did a very professional installation. Hopefully as long as there is no rubbing anywhere I should be good to go. Just got 22.5 mpg (no payload) at 65MPH on I-95 for 111.5 miles. Love my truck!!!!:drink Competely stock w/ 245 65 16 tires. Why mess with success!!! Happy old-fart.

I received the GM letter Thursday, Feb 5th. and took the truck to the dealer on Monday, Feb. 9th. along with my receipt for the lines I bought from Alligator Performance. I received a check from the dealer for $162.00 on Friday, Feb. 13th. Never expected that kind of service!

Tranny lines on GM trucks have been doing this since the early 90's, nothing new.

Best thing to do is get a set of aftermarket lines like the ones from alligator and never worry about it again

Just to tag onto this thread - I just got the letter last week and turned in my receipts for the DRP lines and the dealer labor to replace them. They said they would submit it and get back to me. They didn't even bat an eye at the fact that I bought the DRP lines instead of the OEM ones.

Hopefully I will see a check soon too!

I have a 2008 LMM CC dually and the trans lines came apart and all of the trans fluid came out on the ground. Was towing a trailer and and hit the accelerator and trans slammed in gear and then didn't move anymore. Had someone tow me off the road and got vehicle towed to dealership. Lack of fluid made transmission self destruct. $6000 later, fixed. Just picked it up yesterday. What a nightmare. Now I hear this.

I have been noticing mine leaking since I bought it back in November. This is good to know. I'll run by the dealership on Tuesday my day off and see what they say. I haven't gotten a letter. Probably went to the previous owner.
