My truck has the exact same problem. Jolts when it shifts to second. Doesn't do it everytime. Seems worse when I'm going slow. I don't notice it if I'm really getting on it...I just got on this site today to see if I could get an answer. Someone please help us!
 
Mine is a 2007 GMC Sierra 1500. 58,000 miles. It's got the 6.0 liter. Not sure the specifics on the transmission.

I also have this problem and have talked with others that have. Check with dealer at one time they say live with it they know of the problem but? I bought this truck hoping to have a smooth shifting truck. 07 GMC Z-71

Go over the dealership's head, http://www.gmc.com/contactus/index.jsp
There is a contact us phone number on this link.
 
I had 2 Chevy transmissions crap out on me, and the third is a performance trans that I had built. You don't want to spend what I did, especially if you're still under warranty.
 
That stealership is being lazy. Get to the Regional GM Rep.

#539 of 1486 2005 Silverado 2500 HD Tranny overheating by recon0302

Jan 17, 2010 (8:22 pm)

My tranny gauge suddenly started reading high (almost max) - had everything cleaned and fluids/filter changed but still reading hot - repair guy believes possibly gauge is wrong or computer because he can't find anything wrong - after couple of days it still reads between 250 and 300 after about 50 miles of driving - no other issues other than a "shudder" when pushing down on throttle but that only happens occasionally - any ideas or anyone else hear of this? It's driving me crazy especially since I have been reading about tranny problems others are having. Any advice appreciated. 80K on truck and I bought it new. Thanx.

#540 of 1486 '91 Silverado Tranny by macsown

Jan 18, 2010 (12:30 pm)

I have a '91 Silverado with a 30fried. Whilst towing a trailer, I noticed the truck having problems shifting and no power. I found there was no tow kit and tranny fluid was extremely hot. A month later, I have 1st and 2nd but nothing else.
Before I put out all kinds of money I don't have for diagnostics, I thought I would post here to see if anyone can help.
I am told it could possibly be a "shift coil". I'm not too mechanically inclined so any info would be greatly appreciated.
 
Thanx,
Brian

#542 of 1486 help. 1995 silverado transmission problem by kwadrcr2

Jan 19, 2010 (9:31 pm)

need help. 1995 silverado z71. says check gauges and then transmission or clutch feels like its slipping. it shows no light under the PRND321 in any gear. it only happens every now and then and when it doesnt do this it drives and shifts fine. after shutting it off or leeting it sit over time it basically resets itself and will drive fine after this time.
