You are in the Chevrolet Silverado & GMC Sierra Forum. Your Host is kcram
Owned GM trucks since I bought my first 2WD HD GMC new in 1977. Always been the Chevy guy in the Ford Chevy debates - trucks, nascar, you name it. My fifth GM truck bought new, June 2005. 1/2 ton Silverado work truck - 4x4, I always have tool boxes, ladder racks and usually plows on-board, that's how I make my living. Newest truck has tranny shift problem, GM is aware, has no fix. It's results in a loud draintrain lash clunk that's make me think the universals are going. Also have the lash in the steering linkage/shaft. It's been greased at the dealership 3 times. GM is aware, there is no fix. The rattle is loud when this happens, feels like the front end is going to fall out, I can feel the vibration through the floor. Also, I have the problem when I roll ahead to stop and back into my driveway, my steering turns hard or not at all, until my truck is in motion. It feels like my tires are touching a curb and can't turn. Again, GM is aware of the problem, claims it is normal. Have also had the truck into the garage on 6 occasions when the check engine light came on. I work my trucks, but am easy on them, got 175,000 miles on my last plow truck without ever touching a front end part or having tranny trouble. Also, what part of Southern Florida did the engineer hail from that designed the no-lift windshield wipers. I can't even fit my snow brush under them. Anybody else have excess quality problems with their newer GM?

Ok, I have a slight issue, I have a 4l60-E transmission with no reverse, It had reverse when I took the trans out to replace a broken pump. The truck is locked down and will not move even in neutral. It shifts and everything in other gears, what could the problem be? any clues? |

When I am at low speeds (aka: parking lots,traffic,etc.) It feels like there's a delay when its going forward or in reverse. The best way I can describe it is, it feels as if its loose or hitting against another part. The feeling does not occur at higher speeds. I would appreciate any info on this matter. Thanks

I have a 2000 model (old style) ¾ ton Chevy pickup with 350 motor, automatic transmission and 72,000 miles. A few months ago my transmission shifted hard from 1st to 2nd a few times then started working properly. Within the last month it shifted out of OD on a hill, but would not shift back to OD once I was on a level road. It has done this 3 or 4 times. I ask the Chevrolet Service Manager about the problem and he said it was probably the shifting valves or ignition switch. He said next time it did this, to stop, turn motor off, then start it up again and see if transmission shifts properly. If not, the problem is in the shift valves. My transmission did not correct itself. On this forum an Chevrolet Service Tech said to try LUBEGARD in the transmission and many times it will free the shift valves. I did this: http://www.lubegard.com/automotive/trans_atf_mv.html I have driven the truck over 300 miles and it has shifted perfect, even shifted out of OD on a hill and back into OD once I was on a level road. If I had any money I would invest in this company. Just my opinion. |

| 89 c2500 2wd 200,000 + miles, tranny wont go past 45 mph and sounds like it is struggling to move truck, sounds like somethinhg is turning hard, at times when starting out acts like it slips but then goes, fluid is ok, changed filter or screen and fluid last summer, was great for a few weeeks then acted up again, some days it is fine, not sure what to try, torque converter, tranny, cant afford shop or $700.00 rebuild at this time, need to get gmc on road first. | |
