I had the same problem with my 2007 1500-Classic. It felt like someone hit me in the rear everytime I stopped or it hit hard when shifting from 1-2nd gear. Brought it in at 36k and they greased the the yoke splines. This is just a band-aid to the real problem. I brought it in last week at 76k and they were aware of the problem and have to replace the slip yoke. Sad thing is they are not notifying owners of the problem. You must bring it in if you want it repaired and go through the corrective process. If you are close to the end of your 100k warranty I would suggest getting it in ASAP.
 
I was given a copy of the document describing the problem.

Is that for real?
 
That problem has been around since 1999.

#666 of 1484 ALLISON SHIFTING WHEN COLD .. by sgeorge1

Jul 16, 2010 (2:34 pm)

MY 2001 Sierra with less than 50k miles (duramax diesel) has had shifting problems for the past 5 yrs now, mostly when its cold out (below 50 degrees when it happens) started 3 yrs ago during the cold and got a lot worse quickly..
start it up, let it warm up, drop it in drive and when it makes the first shift (1-2) it goes into neutral! has happened so many times. or the other situation when driving and making a SLIGHT turn,(usually left) take your foot off the throttle and it drops agian into neutral sometimes it recovers and continues, sometimes not. if it drops out, it sits either waiting for you to recycle the ignition (if you do it either wont respond, or drops into 1st and stays there, or third and stays there) or if you stand on the throttle waiting for it to shift, it goes BANG and back into gear. enough to bark the tires. once i drove it 40 miles at 30mph with the engine pegged just to warm it up! if the temp is hovering between 40 and 50 this happens a lot, if its colder forget it youre not going places. right now the service engine light is on and has been for over a year. 2 NSBU switches no fix, allison dealer wants $1500 just to diagnose the problem which they claim may be electrical in nature. personally i am waiting for this truck to be stolen, or a tree to fall on it , or recall, or Jesus to show up :>) im not paying for this any more! corrosion on the brakes are another issue and all the lines under are sh^t as well as the frame.. 50k for a POS
GMC! cant sell it or trade it.. stuck..

i contacted the dealer on this problem and they said there is nothing wrong. I asked if i would start losing gears if it did a fluid and filter. He said,"thats 1000.00 mile oil in there you shouldnt have to touch it yet." On the other side i have a family member that runs a reputable repair shop and he said at this mileage the oil is already dark, and instead of doing f/f, just do a flush. Any help out there?

I would do a drain and replace the trans filter and refill with new trans fluid. A complete flush may cause more problems.

Hello Jwttitze80912,
Unfortunately, I cannot diagnose your vehicle over the internet. Doing a flush won't hurt your system especially if it needs one to be done. Thank you,

#672 of 1484 transmission, maybe? by ekom

Three weeks ago, we purchased a new 2010 Chevy Silverado 1500--4x4. It has 1500 miles on it. We had the windows tinted today (approx. 60 miles from home), and the gear shift won't budge! Of course, it is under warranty, but I am wondering if this is a common problem. A co-worker of mine had a brand new Chevy Avalanche, and the transmission went out at 8000 miles.
