#1 of 1492 97 GMC Z71 Door Sill Trim
Nov 22, 2000 (10:24 pm)
I have a 97 GMC Z71. Bought new, 24,000 mi., taken
"WELL" care of. I have replaced the the "Door Sill
Trim" 2X on Drivers side & 3X on Passenger side.
The trim (this trim includes black strip that
against window) cracks! My Drivers side has just
recently cracked again. Does anyone know if there
is an aftermarket piece available? Interior color
is "Neutral (Tan"). I don't use the panel as an
armrest either. Got any connections at GM to ask?
Thanks for your help.
#2 of 1492 Suspension / Body Bushing Noise
Nov 22, 2000 (10:29 pm)
I have a 97 GMC Z71. "Numerous times", I've had to
spray the Torsion Bar Mtg Bushings with silicone
to stop a "Dry Rubbing Sound" when stopping at low
speeds. Also, I've had to lube the Body Mtg
Bushings for body flex noise. Are there any more
permanent cures? (Maybe teflon lined bushings?) I
like the truck and don't wish to change brands.
sure GM was trying to correct some of these
problems with their frame changes on 99 models.
Thanks for your help!
#3 of 1492 wind noise around the right doors
Nov 23, 2000 (6:44 am)
Does anyone know whether GM has a fix on the wind noise around the front and rear doors on a 2000 GMC ext cab pickup. Dealer has been giving me all sort of comments about he has fixed it but is reoccurs when there is a slight cross wind. Very annoying..
#4 of 1492 Other than changing the weatherstripping
Nov 23, 2000 (8:32 am)
there isn't much the dealer can do. The door hinges are welded on so there is no possibility of adjusting the doors for a better fit. I guess GM wanted to save money on bolts. The solution is to break the welds, adjust the doors, and install bolts to replace welds. They have issued a TSB for the older C/K's on this but none for the newer silverado/sierras
#5 of 1492 Wind noise caused by bug deflector
Nov 25, 2000 (11:00 pm)
I installed a bug deflector on my 2000 1500 ExC SB Sierra and immediately noticed a loud rattling noise around the front window when I was doing around 55 mph. I had heard that some deflectors will cause the rubber weather stripping around the top of the windows to vibrate.
I removed the deflector and noticed that the noise went away.
I decided to exchange the deflector for a different brand and different style and tried it again. The results were better, it didn't get noisy until I was around 65 mph but the faster I went the noisier it got. I decided to put up with the noise for the time being as I am going to trade up to an 8.1 2500. Hope this might help others who are having a similar problem.
#6 of 1492 And how long will that be?
Nov 25, 2000 (11:12 pm)
The Lund Interceptor has been used by Tahoe, Yukon, Sierra, and Silverado owners with no problems. For $50 you may want to try it, unless 1-you can live with the wind noise
2-you plan to trade soon
#7 of 1492 And with your new 2500,
Nov 25, 2000 (11:15 pm)
you may want to order a Lund Interceptor for it, hopefully Lund has one by then....
#8 of 1492 Sierra auto trans COLD shift problem.
Nov 28, 2000 (10:54 pm)
Vehicle: 1999 GMC Sierra 1500, 4wd, ext cab, 5.3
l, 4.10 diffs(rear locking).
Description: When transmission is cold (below 25
degrees)the 2-3 upshift does not occur until 32-33
mph. As the transmission warms, shifting becomes
normal. Under light acceleration, approximate
normal shift is: 1st-2nd: 10 mph; 2nd-3rd: 20 mph;
OD: 35 mph. 33 mph in 2nd gear is 2500+/- rpm, way
to fast for a cold engine (or transmission). This
has been a problem since the first winter (99).
Not a problem in warm weather but the cold has
returned & it's the same as last winter.
Transmission was serviced in Sept (flushed)
w/approx 32K miles. My brother inlaw has a similar
setup (4wd/5.3/3.73/sb)& has the same problem. His
dealer said this was 'normal'. Any advice on this

I have roughly the same vehicle that you do, except mine's a 2000 Z71.
The owners manual(2-23) says that when the temperature gets below 32 degrees, the transmission is designed to shift differently until the engine reaches normal operating temperature. Something about improving heater to performance.
#10 of 1492 Correct

This behavior is by design, it is not a problem even though it may be annoying.
