#192 of 503 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 503 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 503 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)

#196 of 503 tranny problems?????? by missu3 Dec 29, 2007 (9:13 am)
98 chevy Z71 truck shutters really bad when trying to shift into overdrive. i have put friction fluid in tranny and it will quit an run and shift smoothly for 2500 miles. then starts shuttering again. took the truck to a tranny shop. the tech says its not a tranny problem because it gives a code for 5 cylinder misfire. the thing is it only does this when it shutters. doesn't make sense to me because soon as you put friction fluid in the tranny drive for 30 minutes it quits shuttering....

Replying to: blaroche (Dec 14, 2006 7:21 pm) it worked good, it has the 17 bolt pan, dont know what model. the truck will not go over 40mph or so the engine redline. so i assume is the tranny. i changed the fluid today it was a little dark, no metal visible, no burnt smell. no short when i took off the pan or around it, all fuses look good. btw the trany was rebuild dont know when. any help will be appre tk for the help Replies to this message: maxwell10 (Jan 07, 2008 5:30 am)

Replying to: obyone (Dec 27, 2007 11:43 pm) mine is a 5.3L, if it matters much. I was told by the local dealer [near sacramento] it ran $2,100. so total was $2,600 w/a 3yr 100K warranty. as opposed to $1,800 from a well known tranny specialist for him to rebuild and modify chevy impefections and i believe a 1yr but I need to ask. perhaps if I gave him $200 cash more he'd add on 2 more yrs??
#199 of 503 2500 HD Silverado 8.1L Allison Transmission proplems by sorensen2005 Jan 02, 2008 (3:02 pm)
if i dont come to a complete stop at a stop sign, when i hit the gas the transmission does not engage right away and that creates a problem when it does engage and i am at 2000RPM's. My local trans shop (Very well credited for generations) he says to me "Come pick this piece of S#&t up i cant figure out what is wrong with it and noone has any information for me on how to fix it." Has anyone had this problem with their chevy, and how did or would you correct it.
#200 of 503 was working great by biggie4 Jan 02, 2008 (10:02 pm)
I have a 1996 Silverado 1500 5.7 litre It is the best truck I ever had 'till I went to put it in 4x4 one day. Now its pulling to the left like the front left tire is not locking in with the front right. I don't know if its a mechanical or electrical problem? CAN SOMEONE TELL ME SOMETHING?
