Hey Everyone,


Just replaced my 2004 2500 HD (with about 300,000 miles) with a new 2015. Trany felt funny all along but assumed it was just "learning" like they said it would. I now have about 1,500 miles on it. In the past 2 days it has been slipping, running much hotter than normal, chattering right after a shift, totally slipped out of gear while driving, got stuck in 2nd gear a few times, wouldn't go into reverse, etc. Its now back at the dealer. Any one having similar issues with these yet? I do not beat on it and fluid level is good.

For the first two weeks I never saw it higher than 160. While taking it to dealer to have them look at it, I made it to 234. Thats when it totally slipped out of gear. I pulled over ant let it cool down then contnued to dealer. Those are trans fluid temps.

Wow. I wonder what's wrong with it. Hopefully it will be back up and in your hands soon. Keep us posted with what they find!

 

8k on mine so far, and no transmission issues. Might just be one peanut in the turd. :driving:

Dealer called today just before closing and said control valve failed. Tracked one down and should have it tomorrow. Thats all I got for now. Will post more details when I get them.

The Latest....Mechanic dug a little deeper and found metal shavings in tranny. Now looking at rebuild or replace. I'm leaning toward this not being a problem everyone will have. Probably something done wrong in the factory or maybe some idiot took it for one hell of a test drive before I got it. Dealer is cool. It just sucks going from the 2500 with a service body and pipe racks to a mini van. Very limited on what work I could do this week. should have it back in another day or to and will update again.

Not any problems with 2500 hd Sierra with 6.0, 4.10, CC Z71 , 6 SP. Guess there is always one that gives problems.

Glad warranty covers it.

 

Thank you

For "therink", Its a gas job. Got it back last night. Feels like a totally different truck. From what they told me, Tork converter "shit the bed." Found metal shavings, dust and other stuff everywhere. It has been rebuilt completely, the only thing original is the housing. I have a mile long list of parts that were replaced. They guaranteed me I will never be back there with a transmission problem. I hope It all works out. They were going to replace the transmission but had trouble getting one there fast so they rebuilt it. Clearly not something everyone needs to worry about, just one bad one in the bunch. Thank you all for your posts and info. I will update as time goes on.

Last weekend I took my 2015 2500HD on a vacation. Maybe 10 hours into the trip overdrive quit working and the engine light came on. Already depressing gas mileage got even worse as rpm was higher than normal. The last 1/4 mile of the trip it never shifted out of 1st gear! Called the closest dealer (45 minutes away) on Monday morning. Took it in Tuesday morning. engine light had gone out and trans seemed normal. Wasted most of a day waiting for them to verify that there was a problem and get me a rental. I wasted yesterday because they said it would be ready and it wasn't. I just picked it up this afternoon(another day half shot). We leave tomorrow to go home. :( Here is what they found.

 

Black clutches in the pan. Lucky I made it.

Converter and pump cover shot.

They replaced clutches, plates, gaskets, seals and pump cover with new parts.

replaced converter with a reman. Not to happy about that. This truck has 2300 miles on it and now has a rebuilt trans and a reman converter. I work for GM so you can bet they will hear about it.

 

Hope I make it home. I'll probably worry the whole way.

Service torque converters for just about all GM transmissions are reman from GM. No service new converters listed in the parts catalog You work for them, you should know that... :smoker:

Why should I know that? I didn't say that I work in a dealership. In 34 years as a toolmaker in an assembly plant I have never seen a parts book.

      07 yukon xl 6.2 stalls at hot idle and wont restart

      By Jsdirt · Posted

      Holy s**t - not much of a parts thrower you say? You BLASTED that thing with the parts cannon!  You'd have been probably $1,000 ahead if you had just brought it to a competent shop rather than shotgunning a bunch of parts it clearly didn't need.   Just FYI - oil additives are really, REALLY good at ONE thing ... and that's emptying your wallet. They're ALL useless gimmicks.   If that has the L94 or L99, then #7 is an AFM cylinder. I'd suspect a failed lifter in that case.   If you leaned on wiring, sensors, and/or connectors while changing the oil, you'll have to check all that to be sure pins didn't get pulled out, connectors broken, etc.. Old wire loom that was barely adequate when new is certainly brittle by year 19 - make sure wires aren't chaffed and shorting out somewhere where you might have leaned. or supported yourself on it.   If your a mechanic, why didn't you just find out what you were missing and troubleshoot from there??  TIMED spark, fuel PSI / injector pulse, air, compression.  Can't make ANY money going the parts cannon route.

      2027 GMC Sierra: Official Discussion

      LOL! Are you joking?? That wax SUCKS! 100% gimmick made to "look" good.    After just TWO winters I had severe surface rusting in patches over 90% of the frame. Only reason it looks great in the pics is because I SATURATED the frame every single fall with used motor oil for 14 of the 16 years I owned it. Otherwise it would've been sent to the crusher 8 years earlier with the speed it was rusting prior!    I sold that POS 3 years ago. Was a gigantic headache the second it rolled off the showroom floor. Brakes pulsated on the TEST DRIVE. Door trim fell off the 1st week! Interior squeaked and rattled, and the drivetrain clunked after 2k miles. 4x4 switch failed shortly after. Front end - ball joints, struts, hub bearings - all failed between 38k-50k. Engine started burning oil at 50k. Rear and and transmission failed before 100k. Nothing but problems, and frustration with the piss-poor engineering designed to make you give up. Well, it worked! Nothing on that truck was easy to remove ... except the wheels. They haven't figured out how to screw that up yet. Give 'em time ...   I won't make that mistake again. EVER.   Such fond memories ... https://postimg.cc/K1qf23tS  https://postimg.cc/gallery/X02z64J  https://postimg.cc/gallery/mHSRXZv  https://postimg.cc/gallery/D4mMRfL

      OBD not ready?

      By davester · Posted

      Different monitors do their test only under conditions specific to that monitor.  you MIGHT find the drive cycle conditions for the monitor that isn't ready on this site: https://lemon-manuals.la/   If it's not there, then it should be on alldata.com for your truck, but it requires a paid subscription.   And you need to know which specific monitor isn't ready.

      from another thread   Update...although the truck sometimes seems to idle weird and the transmission shift a little weird, I've driven about 7,000  miles and no issues.   However, the way GM has handled my rental reimbursement, the situation when my truck quit, and the recall in general has led me to this point...I have driven a GM vehicle for the past 46 years and unless I buy a C3 Corvette, this is the last GM vehicle I will ever own.
