Gives me hope that my 2014 SLE with 88K has some life left in it. I just hope without the transmission drama.  already had the AC condenser fail once. Impressive it has made the 300K but I would not call it reliable with two transmission jobs.....now my 88 Toyota it was reliable. AC, Transmission, 22R engine never failed thats reliable.

It's the V8 six speeds weak spot. Well, one of them. The worst of their issues. It's a design flaw that shows up eventually. Search Florida Converter on this site. Should find several discussions and links to SONNAX and Florida for the full explanation. The weak converter clutch is aggravated by leaking pump and valve body piston leaks as the bores wear that hastens clutch the lining burning through sending debris throughout the transmission killing it dead. Happens when fluid is used to long and to hot. Some guys have the transmission programed to not lock up until it's in 5 or 6 gear. Perhaps doubles their life. Billet converter won't stop the valve body issues but it will stop total destruction from its coming apart. 

 

Just information, not advice.

Grumpy,

 

Florida torque converters, is that who you are referring to?  I was looking on their site a few weeks ago and never did find one for my truck.  Saw options for 4.3, 6.2, and 6.6 but nothing for the 5.3 6 speed.  I really know nothing about it, just know I'm looking to upgrade mine as I see more and more horror stories continue.

Yes it is Florida TC. Give them a call. They have it.

Not sure if it's bragging or too poor to afford a new one.  Just hit 300K on 2014 GMC All Terrain CC 4WD 5.3v8.    

 

Truck is basically stock.  I purchased it in 2016 with 51K on it.  I immediately did oil change with Edge motor oil.  Have used Edge the entire time changing at DIC stated intervals.  A time or two I have had low oil message on DIC.  Either went in for top off or just got oil changed.  Wix filters were used up until 3 oil changes ago and my local oil shop was bought out by "Take 5"  Now I have no clue what filter or oil they use.  They stated it was equivelent to edge...I'm sure it's probably junk and I'm looking for a new oil shop. 

 

Part failures that I can remember:

 

Air condenser cooler went out at 115k.  I replaced it myself and I guess I broke a clip at the trans coolant line.  That clip let go about 15k later and dumped tranny fluid all over I75.  I buttoned it all up and then at 140k Tranny went out (was probably my fault)  A/C delco tranny in at 140k.  Brake pads at around 180k,  Starter around 200k,  Another transmission at 236k that was covered by A/C delco as the replacement had 100k warranty and didn't make it.  Second Air condenser at 245k.  Front pads and rotors around 250k.  about 4 sets of wiper blades, 2 batteries.  I have a grounding issue that I think is in the negative battery cable.  Starting to get intermittent no start/dead battery issues from time to time....re-adjust negative battery cable and it starts right up. 

 

With all that said.  it's been a great truck.  I've been from Mid GA to Colorado and South Florida to DC is this damn thing.  Also,  during 2021 it basically sat for a year except for vacation trips (so maybe 7000 put on truck in 2021)  I had a company vehicle.

 

So,  I'd like to sell it for 37k that I paid for it in 2016.  It's definitely reliable.  I'm wanting a 24 2500 so bad...but dang they are spendy.

Wow! What a record. No motor issues? Only trans and condenser as major repairs? About lifters?

Update on this thread.

 

No motor issues and no lifter issues.  AFM hasn't ran for over 100k maybe more.  

I replaced ground cable from battery to starter/chassey.  This solved intermittant no start issues.  I had an O2 sensor go out on driver side after header.  (that one scared me....truck just instantly ran like it was blown up) Also now at 349,800.00  

 

My trip to NM elk hunting in the mountains kind of hurt the suspension this past Sept.  I'm hearing creaking and stuff up front.  So I think a pair of quick struts and possibly ball joint replacement is next.  

 

Roll on

      5 Best Slide Down Gameplay Tips! 

      By lanaderay · Posted

      Are you playing Slide Down endlessly but your score is still low? Are you constantly crashing into obstacles as the game speed increases? Don't worry, this article will share 5 invaluable tips to help you master the race and impress your friends. Golden Rules 1. Look one step further. The mistake of 90% of new players is only staring at their character. The secret of experts is to look towards the top of the screen (where the slide is about to appear). This gives your brain an extra 0.5 - 1 second to process the situation and determine the direction of movement before the obstacle approaches. 2. Use gentle movements; don't swipe too hard. Slide Down is very sensitive. Moving your finger too forcefully or with excessive amplitude will cause your character to be thrown off course or crash into a wall. Practise moving your finger with small, decisive, and precise movements. 3. Don't be greedy for gold in dangerous locations. Gold coins are tempting for buying skins, but life is more important. If you see a gold coin right on the edge of a cliff or next to a spike trap, ignore it. Our goal is a High Score, and your score only increases if you survive. 4. Make the most of Power-ups. During the slide, you'll encounter items like Magnets (attract gold) or Shields (temporary invincibility). Never miss them! Especially the Shield, it's your "get out of jail free card" to help you get through those deadly fast sections. 5. Stay calm when speed peaks. When your score exceeds 500 or 1000, the game speed will be very fast. At this point, don't try to think logically; let your natural reflexes work. Take deep breaths and don't panic. Apply these 5 tips to your next game, and your leaderboard will surely improve dramatically. Good luck climbing the Slide Down leaderboard!

      Why I Recommend a Desiccant Air Dryer for Cleaner, Drier Compressed Air

      By lingyuair · Posted

      If you use compressed air regularly, one problem you cannot ignore is moisture. Water in the air line can cause rust, unstable air pressure, poor tool performance, and even damage to sensitive equipment. That is why I highly recommend using a desiccant air dryer. A desiccant air dryer is designed to remove moisture from compressed air by using drying materials such as activated alumina or molecular sieve. Compared with basic water separators, it can achieve much lower dew points, making it especially useful for applications that require dry and stable air. For workshops, painting systems, pneumatic tools, CNC machines, laser cutting equipment, and industrial production lines, a desiccant air dryer can make a big difference. It helps protect equipment, improve air quality, reduce maintenance costs, and extend the service life of the whole compressed air system. Another advantage is reliability. Many desiccant air dryers are built for continuous operation and can maintain stable drying performance even in demanding environments. For users who care about long-term efficiency and equipment protection, this is a smart investment. When choosing a desiccant air dryer, I suggest paying attention to air flow capacity, working pressure, dew point performance, regeneration method, and maintenance requirements. A good model should match your compressor system and actual air consumption. Overall, if moisture is causing problems in your compressed air system, a desiccant air dryer is definitely worth considering. It is practical, efficient, and highly useful for anyone who needs clean, dry, and reliable compressed air.

      My brand new 2007 Silverado's wax frame was rust from end to end partway through it's SECOND winter here in MA. That stuff is completely useless.

      2027 GMC Sierra: Official Discussion

      By Jsdirt · Posted

      I went another direction after losing a trailer tire, thanks to not being able to access air at ANY of the 5 gas stations and garages I stopped at prior, with a Toyota Tacoma onboard, 50 miles from the Canadian border. They were either out of order, access was blocked, or the hose a few feet too short and I couldn't get any closer without risking damage to someone's property.   https://postimg.cc/gallery/X5QJ55w

      I took a 12 second video on my iphone but the file is too big to upload. I will have to figure out how to extract the audio or just do another start with an audio recording.
