Replying to: ruftoyzdawtr (Jun 18, 2009 10:16 pm) I started the truck today and it ran for about 10 minutes before it went out of gear and it made that hissing (air) noise when it did.Started it back up and it moved about 2 ft..you can tell when it's going to go out because of that hissing noise. an ideas? oh I forgot to put the # I got off of the tranny.. 15671928 no idea what it means.
#465 of 502 2000 Silverado 1500 4x4 what's wrong? by krazyk22 Jun 23, 2009 (2:30 pm)
I own a 2000 Silverado 1500 4x4 with 125K miles. Here recently when I accelerate, the truck often revs up into the 3000 rpms, and and sounds like it's going, but the truck doesn't move. I have been assuming it must be the transmission, but could this be something else?

Well I am having the transmission rebuilt.My mechanic said that tranny had NOT been rebuilt and gave me some tips for checking for that.You can bet next time I will.He told me my motor was good so I said just fix it then.He said the motor should last for another 100 to 300 thousand miles.So I am going to take the chance and see.Will let you all know what happens.I should have it back in about a week.The guy I bought it from really ripped me a big one.Oh the tips he told me were to look at the fluid on the tranny fluid..I did that but it was before I drove it.He said the guy probably just changed the fluid is all he did.He said check it before you drive it and after and smell of it to.If it smells like its burnt walk away unless you want to put a tranny in it..I hope that guy knows what comes around goes around..He also said if it shirfted smooth that you couldnt feel it that was bad to..He said you should be able to tell..to feel when it shifts ..maybe this will help someone else so they dont get ripped one like I did.

Replying to: saintal (Jun 27, 2009 6:37 pm) SORRY, NO I NEVER FOUND OUT WHAT IS WRONG. IT SOMETIMES SHIFTS GREAT, AND OTHER TIMES IT WINDS UP WAY FARTHER THAN IT SHOULD BEFORE IT WILL SHIFT. I KNOW LITTLE TO NOTHING ABOUT TRANSMISSIONS SO I AM AFRAID TO TEAR INTO IT THAT I WILL DO MORE DAMAGE THAN GOOD.

#472 of 502 2002 Chevy Silverado Transmission Failure by cajun_okie Jul 09, 2009 (6:46 am)
I have a '02 Silverado Z71 that I have taken immaculate care of since purchasing the truck brand new off the lot in September '03. Earlier this month at 62K miles my transmission went out resulting in the vehicle losing the 2nd and 4th gears. The guys who serviced my truck say they have never seen a transmission with such low mileage so burnt up. The reason is there was excessive space in the clutches for those gears which causes them to slip which in return causes excessive wear and tear on the transmission. Apparently this was corrected in the '03 model trucks. Further, when you purchase a '02 transmission kit for this model truck there is an update that corrects this issue. What really gets my blood boiling is that GM will not admit its mistake and issue a recall for this. I have been told by mechanics at local GM dealerships they keep extras on the floor because the transmission have such a high failure rate. Thanks GM for draining a once loyal Chevy guy's bank account nearly $2,000 to fix something that you failed to correct.

Replying to: cajun_okie (Jul 09, 2009 6:46 am) I HAD THE SAME THING HAPPEN TO A 97 Z71. WE ONLY HAD ABOUT 45,000 ON THE TRUCK AND THE TRANSMISSION WENT OUT. WE HAD USED IT TO PULL A TRAILER A LOT AND EVEN THOUGH WE NEVER PULLED IT IN OD, THE TRANSMISSIONS IN A HALF TON PICKUP ARE JUST NOT DESIGNED TO PULL ALL THE TIME. I DON'T KNOW IF YOU USE YOUR TRUCK TO PULL OR NOT BUT THIS COULD BE THE CAUSE OR IT MAY JUST BE SOMETHING WRONG WITH THE TRANSMISSIONS IN THE ZZ 71 MODELS. IT COST ME ABOUT 3,000 TO REPLACE MINE. I ALSO HAD TO REPLACE THE MOTOR AT ABOUT 112,000 MILES. I THINK THE MAIN BEARING WENT OUT AND SHELLED THE ENGINE. IT SUCKS Replies to this message: cajun_okie (Jul 09, 2009 7:41 am)
