#185 of 506 What was your problem by tinamatt Dec 05, 2007 (7:48 am)
I have an '07 silverado with a scrubbing noise in the motor. Took it to the dealership and was told it was a vibration that could not be fixed. Any thoughts? Replies to this message: obyone (Dec 05, 2007 9:04 am) bumperdude (Dec 05, 2007 11:27 pm)

I have an old k1500 plow truck that was perfectly fine three weeks ago until I got a foot of snow today and I went to plow and had no drive or reverse gears. The fluid is fine. Is it possible that the cable between the shifter and the tranny just broke? If so is there a quick fix im snowed in...

Replying to: tinamatt (Dec 05, 2007 7:48 am) i had nothing like that but the answer that they gave is unacceptable. ask to speak to the service manager.
#189 of 506 2500 HD allison transmission failure by mprevost Dec 07, 2007 (10:08 am)
I have a 2002 Duramax w/ the allison 5 speed automatic transmission. I have 116,000 miles on it now. Replaced the transfer case 2 months ago when it burned up. The tranny now slips out of gear every 1/2 mile or so, usually between 4th and 5th gear. Had it in to the GM certified mechanic twice, 570 dollars later they can't find the problem and recommend a new tranny (rebuild). At their price and failure to fix it after 2 tries I took it to a transmission place. They put in a rebuild Allison tranny and guess what?, it still slips out of gear! Someone suggested perhaps it is the 4x4 actuator switch. It would appear that it is not the tranny itself but no one seems to be able to figure these allisons out. Any thoughts or suggestions?

Hi, Will a transmission fluid leak affect only the high gear. It will pull in the lower gears up to about 35mph, but not in the high gear. It was a quart low on fluid and has been leaking what we thought was oil?

#192 of 506 2001 chevy silverado 4x4 troubles by laura21 Dec 17, 2007 (3:45 pm)
My brother bought a 2001 chevy silverado 4x4 about 2 months ago, and has had nothing but trouble. He had problems with the ABS brake light coming on when he was driving on concrete. It went back to the garage that had 'safetied' it. When my brother got the truck back, the ABS light wasn't coming on, but the trouble was still happening with the ABS coming on. He thinks the garage might have disconnected something that is now causing him even more trouble. He had the front diferential replaced. The trans is shifting intermidetaly, when it shouldn't be. When he's coming to a stop (foot on the brake), his truck actually gets more gas and the rpm's go up. The truck shifts hard (bucks), when he accelerates to 40 kms. When he is driving over 40 kms and touches the brake the tranny kicks down, and seems to get more power then when stepping on the gas. There is a loud nois after the brakes have been operated (w/o the 4x4 on), it sounds like a bad bearing, but knows it's not. He thinks this all has to do with either the ABS, electrical, transmission - or, an immobolizer that a lot of people have been having various problems with. If anyone can please help my brother out, he is a perfecitionist with everything, especially his vehicles. He has spoken to mechanics, and the dealership he bought the used truck from and nobody can help him out. Any advice??? Thank you. Replies to this message: maxwell10 (Jan 07, 2008 5:40 am)
#193 of 506 02 Sierra transmission problems by edg2 Dec 26, 2007 (6:58 pm)
Bought the 2500HD used with 82k on the speedo, about 1 month after the sale the tranny got stuck in low gear, service engine lite came on. I did not have my code reader with me because I didn't need. The dealer had it over nite and said they couldn't find anything. Oyah the lite went out they said. Now 92k same thing, to run the darn thing I have to keep the code reader connected pull over, shut down clear the codes and then off we go for another 15-20 miles before the same thing starts all over. It's a 8.1lt with a 5 speed auto. I bought a $ 2,500.00 24 month warranty with it and I think the dealer does not want to fix the tranny, I've had a lot of trouble from the start. Does anyone know the GM main customer service phone number???
#194 of 506 Chevy 01 Z71 tranny issues by geno31757 Dec 27, 2007 (7:09 pm)
I love my truck, everything's been great until now. 2001 silverado 5.3L all highway miles 147K. I typically drive in 3rd except high freeway speeds. When passing it now slips a bit. My tranny shop[excellent reviews-they service CHP and patrol cars etc.] said i need a $1,800 rebuild and they will "hone" a port larger that allows more fluid to needed areas[torque converter?] I read below a mechanic suggested BP Blaster? Should I? I was also told NEVER flush a chevy's tranny, simply drop the pan drain, change filter and gasket-replace fluid. BUT $1,800??? Ouch. How much is a new one? Am I being yanked around? Thank guys, Geno in No. Calif Replies to this message: obyone (Dec 27, 2007 11:43 pm) geno31757 (Dec 30, 2007 9:51 am) nwalker1 (Jan 19, 2008 6:09 pm)
