  1. Do all gmt400 clusters use that weird plug in the back versus individual connections?
  2. What electrical checks have you done? Ive got to tear through mine and replace worn battery cables and clean up the grounds. My fuel gauge needle looks like its on meth and if I slap the dash I can get the speedometer to turn on or off. I generally will want to make sure the 12V system is happy before replacing anything other then like an obvious leaking water pump or worn belt.
  3. When I pulled with a 4l60e I would put it in 3rd on the highway when the Drive mode would hunt back and forth and not stick with a gear. This happened only when towing a trailer and happened basically all the time regardless of whether I had tow/haul mode on or off. You dont want excessive shift hunting on an automatic transmission, I think because it causes needless excess friction and heat.
  4. Just bought a k3500 2000 reg cab 4x4 at auction. Gambled for a 454 but got the 350 . Engine is..."lean".. but transmission feels freaking amazing. Hobbled it home with really bad front wheel bearings but otherwise looks very clean. Happy to get back into working on these! Did these forums change? It seems way more sloppy and slow on my phone and hard to navigate through the ads. I used to frequent the gmt800 side a long time ago but sold my 2002 1500.
  5. The transmission shop said the torque converter exploded. No real cause known because I barely pulled with it as it was and Im like grandpa level driving speed/acceleration. they replaced it at a huge discount for me because it happened JUST out of warranty lol. Ive had some theories and one of them is poor engine grounding. I read it is possible that electricity can arc in strange ways and cause pitting, which may cause early wheel bearing failures and maybe transmission failure too?. I cant imagine that happening so fast on a rebuilt transmission so I would guess installer tech error or faulty part is much more likely.
  6. I once came close to running dry on the gas tank on a trip to south dakota. There is no reserve calculated in my mile range indicator. The tank holds 36 gallons. I had a post somewhere buried in the past that explained it, it was very accurate mainly because my driving was consistently the same for hours.
  7. If money is tight, the gas HD trucks are capable. You will be underwhelmed for sure going from a 10sp half ton to 6 speed 3/4 ton gas for sure if your experience is a 5,000lb box trailer. But if your thought is heavy duty, these trucks clearly can handle abuse better since everything can handle more torque and HP. If you can afford the $10,000 to get diesel as a luxory, im sure that truck will blow you away. PLUS since diesel gas is easier to transport you have numerous aftermarket options to increase your fuel tank size for even longer towing distance. Basically it comes down to how much you are willing to spend. But I think the consensus is you are probably fine with what you have and if that doesn't change, a 3/4 gas truck will probably not seem like much of an upgrade.
  8. I wish the gas engine trucks had a smooth top hood without the scoop and had all the raised bulk removed. In my opinion the existing air intake routing looks to be better then trying to rig the center hood scoop anyway.
  9. Im having this problem again too. Is the issue the GM mechanics are not orienting the brake pads correctly and just slapping them on like any other? If I remember the TSB didnt it say the inner/outer facing brake pads on the caliper were slightly different?
  10. My beat up 5.3l v8 was pinging with 85 octane towing a 4500sh lb camper. I filled up with 87 and it was fine. That happened when I was driving up in the mountains west of colorado springs. On a newer motor perhaps its less of an issue, but imo i put in what the manual tells me to.
  11. Yet another shocking issue reported with little follow up. give me the juicy details!
  12. I do not like the REV hard folding one. It has quite a bit to do with the dealer installing it however
  13. How bizarre. I will give my 2 cents. These trucks have hill hold brake assist and electric auto parking brakes. If you are suddenly getting locked out wheels, all I can think of is your parking brake is engaging. Perhaps they will find a shorted cable connected to the parking brake equipment that only causes intermittent parking brake engagement that normally wouldn't be triggered otherwise. You said the truck wouldnt move and "N" was flashing so you moved transmission to N then back to D. Perhaps that is what reset and releases the engaged parking brake.
  14. Dumb question but you are installing this on a allison/duramax platform?
