| I have an 07 Chevy 1500 Silverado 4x2. 10 -15 seconds after being at a complete dead stop not moving at all or anything, my truck will clunk and surge forward almost like i was rear ended. The dealer keeps lubing my driveshaft and yolk but that is not it. It almost feels like the truck stops in 2nd gear and 15 seconds later goes "O crap i'm in 2nd and shift down to 1st." i don't know if it is a computer thing or tranny thing or what. Has anyone had this problem as well and got it fixed. I have the settle back clunk from the extended leaf springs that the lube fixes but this is way different. Please post back if you know the fix or anything that could help. | |

I have a 1994 chevy dually 3500 1-ton and am having trouble with the tranny. After driving on the freeways for a period of time then getting off an off-ramp, the truck ssems like it is in neutral - when I shift to a lower gear nothing happens and when I try to put it in park or reverse it won't go in (makes a grinding noise). It drives fine and their is no slippage when I just drive around town, stoplight to stoplight, and drives fine when on the freeway, but when I get off the freewayit;s like it gets stuck in the gear it's in and wont downshift when I slow down. Eventually it will go back into gear, but not because of something I do - just does it by itself? any ideas? Thanks,

| I was test driving a Z-71 4X4 and I noticed a Service 4WD message in the cluster. I tried to press the 4WD buttons but nothing seemed to happen. Also noticed a red led that indicated "N" that is located between 2 of the 4WD buttons. The truck has193K miles on it. If the transfer case or transmission needs servicing, will it deactivate the 4WD function?????? | |

Replying to: dotr04 (Apr 08, 2009 9:43 am) Plastic pistons in the valving process start to crack (older Sable/Taurasourus do) and get stuck in position from freeway speed heat? Maybe gunk collection? Find a trans shop or mechanic you trust. I would expect a shop to be required to do a whole trans redo. Liability issues would prevent a less expensive valve body "patch". |

| Hi, this is my first post. i am a former Dodge service advisor so I have some mechanical experience in trucks. I currently purchased an 03 chevy Z71 ext cab with 5.3l. I have the steering shaft clunk issue. a buddy of mine got a new steering shaft put in which is just like the original. he is starting to have issues again. my suggestion is purchasing a updated heavy duty one through LMC truck catalog. it runs about $379.00 and claims to solve this issue. second, I also have the 2nd to 3rd gear shift clunk underneath my truck at low speeds or going up hills. Another buddy of mine has an 04 sierra ext cab Z71 with 5.3l and had the same issue at 22k miles. He got this issue fixed at the gmc dealer where he lives, they replaced his driveshaft with a beefier one which looks like a 2500hd shaft not sure though but definately beefier than the stock one. he now has 40k miles and says he has had no further problems. Hope this is helpful, I plan to do the same with mine and also put the steering shaft from LMC when i have the money to do so (Damn Economy!). Overall i am pleased with my truck and absolutely love the ride, though not as exciting when flooring it like a Hemi but still satisfies my needs! | |
