  1. LOWERING Z71.....

    I’m sure you could. But perish the thought of WHY ? Lol Sent from my iPhone using Tapatalk
  2. 2002 Avalanche Z-71 4WD issue

    Thanks Gavin. Mine doesn’t have a mind of its own and tries to shift where it wants. It just won’t shift where I direct it to shift all the time and I noticed the illumination issue to be possibly related ? Not sure, but when it illuminated, it did drop into 4 low.

  3. Hello fellow Chevy owners. I own the above listed Avalanche. I keep it @ my hunting lease to use filling feeders and hauling bags of corn. It gets very wet and muddy during that season. It’s a drought now. My issue is, I’ve been experiencing issues of it dropping into 4WD low. It drops into any other Auto 4WD and 4WD Hi. Here is what I’ve recently discovered. My dashboard shift indicator, when shifted to neutral to engage the 4WD does not illuminate. When it momentarily DID illuminate, it engaged into 4WD Lo ! Now it’s stuck in low. Can’t get the neutral position to illuminate. Drive, And reverse illuminate and park intermittently does. My question is, being this is an electronic shifting system, is my electronics telling my transfer case it is NOT in neutral therefore won’t drop into Lo or out of Lo ? If so, what is the module part that is responsible for this dashboard indicator ? I might as well replace it. Already replaced the 4WD switches, and was thinking of the module that mounts outside on the tranny thinking it got wet ? That part is a $250 part so if I can try something less, I win, and this observance I discovered opened my eyes. I did notice recently this year, this shift indicator not fully illuminating. I got all my shifts but not my 4WD buttons linking to it. Any advice from experience would be greatly welcomed. Thanks in advance Mike Sent from my iPhone using Tapatalk
  4. Why do I keep thinking the water is not circulating well enough as the engine is working ? There should be enough air flow @ 60 to keep it cool enough. But if the coolant isn’t moving around freely from constriction or blockage it gets hot. Could be water pump, which was replaced, thermostat which was replaced, could the hoses be collapsing from air pockets possibly ? That would mean, there might be room for more coolant into the block while @ rest. Also, coolant diluted enough with water ? Sent from my iPhone using Tapatalk
  5. So you didn’t notice your vehicle being restricted by your brakes ? Wonder if you’re not getting all your gears ? Are your RPM’s a bit higher than normal while going 60 or so ? Sent from my iPhone using Tapatalk
  6. You seemed to have replaced anything that’s needs to be replaced. Since you do not have a fan clutch we can eliminate that. Have you inspected coolant circulation with the radiator? Is it possible water pump as you day just isn’t pumping ( impellar) issue ? How about your belt and harmonic balancer pulley tension ? Could it be possible your belt tension just is not driving that water pump to crank ? You would have noticed amp issues from the alternator as well ? The crazy part is, textron pink is where it seemed to originate from ? Weird. Tranny cooler circulating ? I’d start the engine with the radiator cap off and let it warm up until the thermostat opens to view coolant circulation first. Then look at the belt tensioner next, then finally water pump which should be connected to coolant circulation unless you are clogged. Sent from my iPhone using Tapatalk
  7. It might have a neutral safety switch which cuts off the engine upon big impact in order to avoid an explosion. Check to see fuel is pumping and you have spark. I have heard of Ford’s having this and am thinking it’s a across the board safety item for all vehicles. Sent from my iPhone using Tapatalk
  8. 2005 Silverado oil pressure problems

    Have you checked the accuracy of your gauges ? Are your oil returns / oil pick ups sludged up ? Is your oil pump working well ? I remember years ago, in the GM 231 engines they had an external spring that assisted the oil pump. The spring would fatique you had oil pressure loss and lifters rapping. 2 bolt switch out on the side of the pan fix. So pumps do lose their ability to pump. Sent from my iPhone using Tapatalk
  9. Grinding noise when accelerating past 60 mph

    I’m with a ujoint. In time it will get a bit worse at lower speeds. Outside chance the pumpkin [emoji316] because you heard a clunk and GM is known to have some clunks in the rear end. Sent from my iPhone using Tapatalk
  10. A/C blower motor

    Sounds like a bad switch relay being you replaced everything else. Sent from my iPhone using Tapatalk

  13. I just replaced my dashboard 4WD selector switch. I read how they have given issues. This didn’t cure my issues but it doesn’t hurt. Mine says service 4WD. I’ve had rats [emoji232] inside so we are thinking ate up wires somewhere now. Sent from my iPhone using Tapatalk
  14. Hey y’all My big red that I use to fill my feeders @ my camp had an interesting situation happen. First, I thought I had a hung up caliper and had some burn/heat coming from the left rear wheel. Seemed to loosen up as I felt the wheels were free ? Next thing a bit later on and possibly totally unrelated, my big square info center light on the dash says service 4WD. All the 4WD lights to switch from 2WD to 4 low, 4 high or auto 4 WD went blank. I got to thinking maybe I had a leak ? Truck was still driving well. Did not try to drop it in 4WD after that, and dumped it off to a local mechanic to get diagnosed. I’m not sure if it’s a sensor and a hung caliper or something strictly 4WD. He’s afraid he doesn’t have the equipment diagnose it so I’m thinking send it to the Chevy dealer. Anyone have this service 4WD light come on and what did you find wrong ? Any help is appreciated. Thanks Sent from my iPhone using Tapatalk
  15. Auto 4WD works, Fulltime 4WD doesn't

    I had a simile issue with my buggy truck, 2002 Z71 Avalanche. It was a sensor on the axle not working properly. Sent from my iPhone using Tapatalk
