GMC did however have a "GT" which was just a trim package like the Chevy "Sport" pkg of the '90's. The "350SS" decals you see are add-ons. The only Pickup SS was the '90 - '93 Chevy 454SS. Do a search for "auto decals" and you'll find loads of companies that specialize in them.
#1118 of 1492 Antifreeze by mailman2 Aug 14, 2005 (8:24 pm)
I have a 2001, 1500 Z-71, 5.3 with 35,000. I'll be changing the AF and trans. fluid. Should I stay with GM'S dexcool or go to Prestone? Any suggestions on changing tranny fluid, What kind, should filter be changed or power flushed? ANY HELP? Also, is there a drain plug for tranny fluid?

Replying to: mailman2 (Aug 14, 2005 8:24 pm) I would stick with the dexcool which has a longer useful life (5yrs. or 100k) and is available at auto parts stores. Not sure if standard antifreeze will cause any issue, I would think not but hey this is a GM vehicle subject to it's own little quirks. The tranny pan does have a drain plug if I recall but you should change the filter if you change the fluid. Curious as to why your changing the fluid? is there a problem? These systems are closed and not subject to outside contaminents, owners manual says not to touch it for 100k unless used for towing or heavy service then do it 50k. My buddy who owns transimission repair business says the same thing, unless there is a problem don't mess with the tranny. He also stated that these quick oil change places push for the "flush" and change because it's a money maker not a necessity. They use questionable scare tactics in getting you to do it similar to selling you a "motor flush" because of sludge build-up. All smoke and mirrors to the unsuspecting or uninformed consumer.   Ray T. Replies to this message: phaedrus411 (Aug 19, 2005 5:53 am)
#1120 of 1492 Air coming from under dash after brake job by sticks2117 Aug 15, 2005 (8:08 am)
I did a full front brake job on my 95 gmc and know when I press the brake it takes a lot of effort to stop the vehicle and I have a like a hissing sound coming from under the dash Any suggestions as to what it might be I did all the test for the booster and they all check out fine the booster shows to be solid Replies to this message: obyone (Aug 16, 2005 11:38 pm) rayt2 (Aug 17, 2005 9:45 am)

Replying to: sticks2117 (Aug 15, 2005 8:08 am) Did you bleed the brakes? Top off the fluid?
#1122 of 1492 Re: Air coming from under dash after brake job [sticks2117] by rayt2 Aug 17, 2005 (9:45 am)
Replying to: sticks2117 (Aug 15, 2005 8:08 am) Bleed the brakes again, sounds like you still have air in system. Start at right rear then left rear then right front and left front. The idea is to work from farthest point from master cylinder to closest point. Let us know the results. There is nothing under the dash that would cause a brake system air leak.   Ray T.
#1123 of 1492 Re: 2000 4.3L V6 won't start [gmtruckguy] by weels Aug 17, 2005 (8:54 pm)
Replying to: gmtruckguy (Aug 06, 2005 7:04 pm) Man! I know you checked the battery terminals but this really sounds familiar. My old 96 was doing that and every thing looked fine on the terminals till I peeled back the insulation over the connectors. I ended up replacing the battery cables and it was fine after that. Sometimes its good to undo the battery and soak the ends of the cables in baking soda and water for a while. I never cared for the side mount connectors. You can't inspect them like the top mounts. I hope you get it figured out without too much more cash. Good luck!  - Tim

Replying to: rayt2 (Aug 15, 2005 6:47 am) Don't use DexCool unknowingly. This antifreeze, though marketed as "sterile", has been shown create a residue in the cooling system that can block flow and even eat away at the gaskets. This is not smoke and mirrors; there are several class action law suits being brought against GM at the moment for their continued use of DexCool and supposed knowledge of this problem. As GM has used DexCool exclusively for a decade or so, a recall is not going happen as it would most likely cost the company in the billions of dollars.   Continuing to use DexCool probably will not harm your vehicle. Just understand that the 100,000 mile slogan is bogus. When you have your coolant changed, get the system fully flushed to remove the residue and continue change it every 2-3 years.
