I had my '99 Silverado Lt Extended Cab 4WD in for Service today. With 20 Miles left on the Warranty.
I asked them to check everything out and especially anything they would have done to it if it were their truck based on past problems they have seen and TSB's. Maybe that's nieve of me but, the service Guy has been straight up with me in the past and not recommended any crapola, so dare I say I trust him?
Based on some postings on this board when I took it in I did note:
#1 Rough Running at Start up when cold ( so I left overnight and they put a monitor on it and fired her up next day and said no problems noted)
#2 Wind noise in rear passenger windows - to which
they indicated they "Tightened" some molding behind driver side
#3 A finicky heater control (difficult to get comfortable either too hot or nearly cool) - they tested temp on full half and another position and said they had variable temperature readings thus OK
#4 Noted the "clunking" though this has only occured once since the "Fluid Flush refill" and asked for the new Yolk - On Order to replace when it arrives.
Well I picked it up today and the darn thing stalled out on me at a light 8 miles form the dealer (first time anything like this has ever happened) - Called the Service guy on the phone and he said may be due to injection cleaning (not dry?) and he told me to let him know if not Ok tomorrow. Does anyone know if that could have been the cause? (And was I a sucker for spending $90 on this??)
But my primary question is this,with my warranty near expiration, what do I want to be sure gets corrected?
I am going back through the posting now but a slow process, some of you experienced guys/gals can probably rattle the main ones off.
Any guidance is appreciated!! Thank you
Other background on me and the truck..
My first glimpse of a Silverado was about (May/June?) of '98 on the Chevy web site when they sneak previewed the new body style, sort of masked with a bunch of add ons so you couldn't really tell what it looked like (if my recollection is right it looked more like the avalanche in those previews), I kept checking and reading until they finally released the "real" pictures and colors, knew I had to have one and special orderd it in Feb '99 got It in May '99.
It's been great so far, with just the inconvenience of the few recalls, seat belts, brake pipe, etc. But really Love it it and have babied it. The only "service" I have had has been the standard recommended stuff. I hope this is a truck that will last as long as my '91 S-10, which now has 192K but is about pooped, fouling plugs, and burning oil etc. but hey I've got my money's worth out of it!!

1.) During the first 5-6 miles of driving the truck doesn't want to shift into over drive and when it does, it gradually shifts( not like my dad's 92 that when it shifts it will jar your teeth. Dealer tells me that this is normal because the tranny needs to warm up.
Is this true??
2.) When it is cold (below 28 degrees F) when the truck reaches a speed of 25 miles mph the tranny seems to whine, kinda of like the sound oversize tires make on a rough road, after you accelerate through it it goes away, after the vehicle is driven a few miles and is warm the problem won't repeat. Also if you acelerate quickly you don't hear the whine either, but since I don't lay rubber in my driving habits the whine rather annoys me and summer is a ways off.Has anybody else experienced this? Since I haven't bought American since my Chevy Vega fell apart 28 years ago, I thought I would re-vist the domestic scene.
PS: to the Tundra guys, I think the Tundra is a bit crampy and the "Rado is much more comfortable, but hey, what do I know, I've been in a compact for so long I didn't know how nice it felt to stretch out.
2. True
Has been happening on my truck for 2 yrs with no problems just gotta let it warm up
Still wondering if that Fuel injection cleaning was worth the $90? But I guess that's sunk now anyhow.
Thanks again,

I have scanned the nickel plated slip yoke tsb and the one for new 4 door latchs (ext cab doors hard closing when cold)
Thanks!
Send me an email to remind me ok
Last I heard was that GM is advising not to install it and that they were working on a third fix.
The nickel plated yoke works for about 3000 miles and then the noise comes back. Similar to greasing the splines.
Here is the original TSB

This bulletin is being issued to advise dealerships to no longer flush and replace the transfer case fluid when a customer comments about a "bump" feeling when the vehicle accelerates from a stop.
When Corporate Bulletin Number 99-04-21-004 was issued, a new transfer case fluid had just been developed to correct this condition. Currently, a nickel-plated slip yoke is being developed that will correct this condition. A new bulletin will be issued as soon as parts are available.
Please share the information in this bulletin with customers who may inquire about this condition.

I originally posted #1738 on these problems and went to the dealer in January. The hydraulic lifters and the limited slip are "live with it" sort of things. The limited slip is a design thing. The hyraulic lifters have been a complaint with other customers, but the dealership has not been able to fix, even after taking one engine apart. So, if the lifter does not make the noise all the time....live with it.
The muffler is a different story. They believed me about the "oil can" problem and ordered a new one, indicating that others had the problem too. The "oil can" noise is what you hear once when the muffler is heating up, and again once when it is cooling down. It probably helped that I told them what I thought was wrong inside the muffler, based on having worked for a muffler co. for many years. Well the new one has "loose insides." Parts inside the muffler rattle a lot when cold. You can hear the parts rattle when you tap the tail pipe or muffler with your fist. We are waiting for another replacement muffler.

A lot of us use Mobil 1 or other synthetics in our engines - but I don't worry about the engine -it is most likely going to last much much longer than the GM tranny. Anybody have a auto trans fail after using synthetic trans fluid? Should we all start "GM tranny savings accounts"?
Ray T.
The fan has a built in thermostat. It free-wheels when cold, but engages when more cooling air is needed through the radiator, at which time it will make more noise.
