  1. Had a few days off this week before I start my new job on Monday, so decided to tear back into the headlights. I can’t ever leave anything alone!!! Removing the old permaseal was a complete b!tch. When I opened them up the first time to install the Klearz, I went the easy way out and just mashed the perma down in the channel and put butyl over top of it. About 4-5 hours to remove everything and multiple times in and out of the oven. On top of that, I put a bead of clear silicone around the edge after the new butyl dried so had to get that off too. Live and learn... Took the chrome bezel out, used Easy Off heavy duty oven cleaner to strip the chrome. About 10 minutes in on the picture below. 30 min process and it results in gloss black. Installation of Diode Dynamics switchback DRL boards was next. Pretty straight forward process. 5 min epoxy to secure the boards. Reassembly of the lenses and bezels. PG9 cable gland on the back of the housing so I could mount the LED switchback drivers on the outside of the headlight. Wired it all up and test ran before sealing everything back up. Everything is good to go so back in the oven and sealed up! 250F for 10 min to soften the Diode butyl. And the final results. Super happy with how everything turned out!

Some rub but easily remedied Diablo i3 Platinum - 93 canned tune w/ Some of the parameters changed. Will possibly go with Diablew in the future. Let me know of any questions. Maybe I should post a build thread with more pics and detail.

  7. 3 people you know, its "common" to you. Been at a GM dealer for 12 years. Its not as "common" as lead to believe, but yes, they do happen. Out of all the AFM/DFM trucks we've worked on regularly in 12 years (hundreds to thousands) 99% of them have never been apart for lifter replacement. Low and high miles. The internet and social media make it sound like every single truck built has had a lifter go. Not the case. Hell, I think in the last 5 years we've had more 6L80s come out of trucks than trucks have come for lifter failure.

  8. I take it that the converters are not balanced? I would think they are before any fluid is added. Drilling and adding a drain plug would put it out of balance. To me anything that rotates like that needs to be balanced, just like our tires and driveshaft.

  9. That's cooler than I would have thought. Think I saw 104 F as a 'trigger' in a tuning table 1SLOW1500 showed once. Unlike the motor 'moisture' is not generated in a transmission as a combustion byproduct. It's absorbed from the atmosphere. Here's a pretty good writeup from Machinery Lubrication on that topic. https://www.machinerylubrication.com/Read/192/water-contaminant-oil Some moisture is present in ALL lubricating fluids. The object of the game is controlling/limiting the concentration levels. The easiest and most effect way of controlling its concentration is by regular fluid exchange. Take a breath.... the severe schedule in your manual is normally often enough. 45K. Personally, I do a partial every 25K. Color is a good indicator. Hazy is approaching the danger point.

  11. Found this TSB released last month stating there is a factory offered "fix" for those who want to do away with the idle time-out. #21-NA-228: Full Size Trucks Idle Time-out Disable - (Oct 21, 2021) Involved Region or Country United State, Canada, Mexico, Middle East, Israel, Palestine Additional Options (RPOs) BTM Condition Some customers may comment that currently if the vehicle is left parked and running with the RKE transmitter outside the vehicle, it will continue to run for up to half an hour. If the vehicle is left parked and running with the RKE transmitter inside the vehicle, it will continue to run for up to an hour. Cause This condition may be caused by GM PEPS vehicles were designed with an idle time-out. Correction In certain situations, the customer will request that this feature be turned off because they need to extend their idle time. A calibration is available to eliminate the idle time out feature. If this calibration is installed, the dealer will need to print the Owner’s Agreement Statement attached in this bulletin and put it with the Owner’s Manual. This is a customer pay repair. The vehicle owner is responsible to be aware of any local ordinances that restrict prolong idling.   Important: The following needs to be a separate page in the bulletin and the dealer will have to print it out and place it in the glove compartment or Owner's Manual. When the vehicle was produced, it came with the auto-shutdown feature enabled. If you are not the primary owner of your vehicle, please note that this feature may have been disabled by a previous owner. The vehicle owner is responsible for being aware of and complying with any local ordinances that may restrict prolonged idling. The vehicle owner can have this feature re-enabled at owner cost at any GM service center.

  15. A little off topic, but cannot tell you how many people I have written up for not wearing a seat belt while driving a fork lift (PIT). Oh, we were just going a few feet, and then they crash, kill someone, or drive off of the dock killing themself. Maybe the thinking is, it slows you down, and hopefully you are forced to be aware of your surroundings before taking off. JMO.

  18. Most likely its not metallic at all. The alloys and sintered "swarf" coatings materials mix with gasket making bonding agents, some swarf, are swirled and dispersed to the engine oil and while they might have a slight magnetic capability if you checked them in the oil pan they are usually inert and not actually wear. The phenolic, amine, and other polymers from engine oil and gasoline fuel additives in this care can reflect light and look metallic. Dyes even play from oil and fuels and mix with all that other swarf to reflect sunlight.

  27. Not to be a kiss butt sap, but Thank you guys so very much. This forum is a goldmine of information. From Transmission thermostat deletes to suspension overhaul to what kind of differential oil and many other topics, I can count on GM-Trucks.com and you fine folks to have 14 different ways to do things and valid and helpful thoughts on topics as well. I like to think I'm a decent DIY guy but I could not do it without you guys. Any given day I can log on and I learn new stuff, like the upgraded trans thermostat, or new TSBs for fluid specifications, or tips and tricks to make life just a little easier. It's great to know such a great resource is just a click away, and it's because of the cool dudes (and some dudettes) that frequent this site. New project coming up? Check GM-Trucks. What's the scoop on a common K2 problem? GM-Trucks. What's the best way to tackle a tricky part replacement? GM-Trucks. After the good experience I have had with my Cadillac forums, I started looking for one when I first got Clyde. I'm so glad I found this site. Thank you guys.

  28. I know this is late to the game, but I'm happy to provide some confirmation bias for you After my 275 55R20 Goodyear SRAs became drag slicks at 35k I put Michelin Defender LTXs on in the same size. Great tire, great traction, great treadwear, no noise, they handle hooligan driving well (think leadfoot launches and taking corners a little hot hahaha). I believe all Defenders are rated to 70k, I got 81k out of my first set with religious rotation and relatively close tire monitoring. I had a bad habit of running the pressures a tad high so the centers were at 1 or 2/32nds when I replaced them. My second set I got 67k out of them. Again, had a bad habit of running the pressures a tick high so the centers were wearing faster. The second set I replaced a bit earlier, i think at about 3/32nds just cause I had the tires on hand and I had a fairly long trip coming up (went from Casper WY to Las Vegas 7/4 to 7/9/21). Third set I'm rotating every 5k miles like I always do and am monitoring tire pressures much closer. Happy to report after 15k miles they are down to 11/32nds (from 12 new) and are even across the board. Michelin makes the best tires money can buy. Dad has run them on his Suburban, Escalade ESV, DeVille, first DTS, and his current DTS. They ride great, handle great, are quiet, and do great in inclement weather. I've run them on my DeVille and my Silverado and have equally high praise. Tried Goodyears once on my DeVille and they just are not as good of a tire. Same experience with my Silverado. The stock SRA Wranglers were ok but performance plummeted after 35k. Dad had Goodyears as OEM tires on his Escalade and had a tread separation at about 50K. Yours may be different cause of the different size but I think you will be very happy. Excellent choice!

  29. I'm a retired construction worker. Your truck is the most expensive tool you own. Take care of it and drive it for years. Fuel cost is directly related to the price of gas. Idle time, foot control are your best deterrent. There is no magic chip.

  30. Results are in STL010 average open highwaytemp is 140 Heavy city use is up to 197f stays at around 197 if I idle for an extended period flipped stock thermostat average open highway is 150f Heavy city use is up to 176f Temp goes down to 167 if I idle extended periods. same constant average load of about 600 pounds of loaded pallets with batteries in my bed with same routes and stops … All day for about 8 hours of total engine hours. 50/50 city highway. Average California 90 degree weather. both tests were done in literally the same circumstances very consistent 2019 Silverado CC Z71 8l90 with 51k miles transmission has had 3 drain and fills of about 6 quarts each time since purchased new. With blue label Mobil 1 atf. Filter was changed out 1 time at around 20k miles Front and rear diff are running Amsoil 75w90 since 50k miles. engine has had Mobil 1 0w30 since new no issues. and recently I’m trying out 5w30 Penzoil ultra. Always changed oil at 5k miles since new. No DFM disabled lol running it stock.

  31. Plenty of discussions with the dealer and techline in regards to the operating temps that GM set forth on the powertrain for our Tahoe. They said both engine and gearbox temps were normal and as expected... I ended up doing a Katech 174 and trans thermo pill-flip about a year ago and have been much more happy ever since. And now this is released for the gearbox... https://gm-techlink.com/?p=15389 Little bit of irony.

  33. Quick tip for everyone in this thread. 2014 and early 2015 V8 trucks, yes, this is correct. The trans cooler lines hit the radiator, then go out to the aux cooler at the top of the condenser. However... This is NOT the case late 2015-2019 old body V8. They no longer touch the main radiator at all. They are dedicated flow to the cooler at the top of the condenser. See pics below. I added some red lines in case the lines GM drew weren't 100% clear connecting the lines to their proper fittings/other lines. Again, V8 only, the V6 doesn't have an aux cooler and only flows through the radiator.

  34. Definitely the worst part about living in the midwest with a black truck. I try to hand wash at a self serve place once a month, but what a PITA and then it usually snows the next day anyways. I need a shop with a wash bay..

  35. In addition to an air bag, modern cars and trucks have crushable steering columns as a safety feature to prevent the driver from being "speared" in a head on collision. Hopefully the use of an air chisel has not affected the column's ability to collapse in a wreck. Rather than using a washer to fix the problem, you might want to get the column checked out by a professional.

  36. It's been a long ride but this week I should be picking her up from the shop. Got a fully built 416 long block from Texas Speed and performance with the EL-C7 cam. Camshaft w/ +32% Fuel Lobe: 231/240, .645/.635, 113 LSA, 109 ICL. Also put in a circle D 8L90 PRO SERIES MULTI 258MM high stall torque converter, LT4 fuel pump, LT4 injectors Tuner has it running getting around 435 rwhp with stock intake and throttlebody. I have a Katech 103mm and MSD Atomic intake but it seems like a pita to install (adding idler pulley and angled adapter. LT1 intakes are angled different). So we are going to try a stock ported l86 intake with the ZR1 95mm throttle body and hopefully that gets me some more horses. I also would really like to see the dyno charts because a stoker should pick up bunch of torque and horse power may not increase as much. I will update https://www.texas-speed.com/p-4418-tsp-416-cid-gen-5-lt1-long-block.aspx Pic was getting towed to shop on 7/22/21 with blown engine.

  41. Bravo!! I keep them until there is nothing left (rust) to hang parts on. Most of the time I've been blessed with vehicles that last 20+ years of very trouble free service. Yes, I've had a stinker to two and no I still didn't give up on them until they give up on me. That blessing is a result of a good PM program. One I learned at fathers knee and refined with 50 years driving/building/racing experience. Vanity is not part of my car buying equation. I don't believe in false economies. I rarely buy new. Twice in fact in my life and in both cases the 'deal' is what I bought. A deal that to buy new was cheaper than a two year old low mile purchase. Both were bought at or below 'auction' price missing entirely the first year depreciation. I look at the vehicle as a transportation device. Not a gaming center or office or music hall or a cup holder for six or a makeup table or communication center or ___________________. It moves me from point A to B without causing discomfort or undue stress. The less it has the better I like it. A few notable exceptions. Cruise control is a must anymore. There is no cheaper vehicle to own than a paid for well maintained one. Anyone who decides buy a $50,000 vehicle because a brake job on his current ride cost $1,500 or a motor cost $7,000 in an otherwise sound vehicle is looking for a reason to own something 'different' not cheaper.

  42. Assuming fuel cost is a wash (I don't know if you included that in your monthly cost), insurance premiums cost more based on the replacement value. Also I know some states charge annual plates/tabs based on vehicle value (Wisconsin doesn't so I'm not too in tune with that.) Everyone knows depreciation is worst in the first year. Now the last year has been a bit crazy, but I'm talking in general. That said, it is definitely cheaper to operate an older vehicle. You can debate the monthly payments vs regular maintenance, but keeping a vehicle for several years after its paid off always puts you ahead. Some people value having their ride under warranty, so always paying a monthly fee gives them peace of mind. I don't believe that is worth it in the long run, but its a personal choice. I have an extra vehicle so if one needs work, I'm not stranded. I have owned my vehicles for 8+ years on average and I don't plan to stop that trend. My wife would prefer a new one about every 5 years. Purely from a money standpoint, I think it is wisest to own vehicles around 4-8 years of age. Some people are more trendy than I am though. My 2014 Chrysler 200 work beater is bare bones, less to go wrong. Give me an FM radio and a heater and I'm good to go.

  47. All of the concerns would be eliminated if you change the fluid IMO. Short cold trips, switch to a 100% synthetic. Red Line? If you use semi synthetic fluid, 25 k exchange? Using 100% synthetic, 40 -50 k? Me and Grumpy have preached more fluid changes are good. Has worked for me for along time.
