| I have a check engine light on in my 2003 GMC sierra 2500 h.d with the allison and when I scan it a p0700 transmission code comes up and wont erase. The truck also has no reverse lights and the steering column indicator does not work, along with DIC (driver info center) could this be linked or just a coincidence. It seems to shift and operate fine. Just wondering if anybody had a issue like this or simular. | |
| My '97 chevy does not want to shift from 1st to 2nd at first, but after it does I can drive a hundred miles and its fine. This problem is getting more frequent and lasting longer everytime. If anyone knows anything I could sure use some help. Other than when I very first take off there is no hint off a problem. | |

Hey everyone. Bought a 05 Silverado 1500 5.3L last week. It has 87k on it. I am a fleet manager and I only run Chevrolets and have been proven to the durability of these trucks but I may be proven wrong with this truck. I started noticing the other day that while driving at around 45 mph, without the cruise control, the truck has a lot of bucking and jumping and vibration. Had the tires rotated and balanced today and it still seems to be getting progressively worse. I have also noticed that when driving from 40-60 without cruise, the RPM's have a lot of fluctuation... and by the way, this is annoying as crap now that I have Flow Masters! I have also started noticing that every once in a while, the transmission slips when shifting from first to second. I have never seen this kind of problem out of my trucks at work so I am stumped on where to start. Anyone have any ideas? Thanks! |

| i have noticed a few people mention the tranny clunk after stopping, mine doesn't clunk but it does seem to still be engaged when I try to stop,it is very hard to get it to stop easily, almost like having a very heavy trailer on the back. If i take my foot off the gas pedal, it will basically maintain that speed for at least 6-10 blocks, mainly between 45-55mph. I have never driven a vechile that doesnt slow down when your foot is off the gas? The tranny also hesitates for 2-4 seconds between the 2-3 shift point, almost slams your head into the steering wheel. I can feel vibrations through the floorboards & it seems to shutter in all the lower gears & the exhaust is extremely loud & odd sounding. On 4 occasions I have experienced a "surge", that is I released my foot from the gas pedal & the RPM's increased 500 & the engine sped up, lasts 3-5 seconds. Guys I have had this death trap into 3 dealerships, 1 of them 3 different times, the 3-4 clutch plates have been replaced, pcm upgrade, new PCM/computer installed, the pcm relearned many times, by the way this solves all the issues for about 500-800 miles & it morphs back into its old self. GM is of no help, 80 hours on the phone with them, now district rep in detroit is on the case, laughable. So please do not feel alone in your troubles, keep fighting, they want you to just go away that is their idea of customer service. If your new GM product works then I'ld knock on wood.Good luck | |

| I HAVE A 89 CHEVY HALF TON PU, TRANSMISSION IS SLOW TO SHIFT, HAVE TO WIND UP THE RPMS, THEN IT SEEMS TO SHIFT FROM 1ST TO DRIVE SKIPPING SECOND. YOU NEVER FEEL IT SHIFT INTO OD AND DRIVING DOWN THE ROAD I CAN SHIFT BACK AND FORTH FROM D TO OD AND YOU CANT FEEL ANYTHING BUT IF I LET OF THE GAS AND SHIFT INTO D OUT OF OD YO CAN FEEL IT SHIFT DOWN. ALSO IF I SLOW DOWN TO MAKE A TURN IT WILL SHIFT BACK DOWN INTO 1ST OR 2ND, CANT TELL WHICH ONE FOR SURE. ANYBODY GOT ANY IDEAS? | |
