Hey All, speaking to a neighbor today, said he was looking at buying a 14 like mine.  But, he is finding one with the Transmission Replaced, because at around 100K Miles these 6 speeds Tranny and Torque Converters go out.  My truck has 92K, Should I be Worried?

You can always have a transmission shop do a drop and fill your transmission. If you take it to the dealer they will push for a  transmission flush, but if you push for a drop and fill, talk to the service manager about your concern. If they do a drop and fill try to be present when the pan is taken off so you can look for your self. You still have 8 thousand miles left on your 5/100000 powertrain warranty? If everything looks good to you have them put in the Mobil 1 Synthetic LV ATF HP. 

 

 

This only my suggestion don't take my word for it research and talk to a transmission shop.

So, after all the really strong advice, would you take your truck on a 3000 mile trip without any worries?

 

If not, I might think about seeing what else is out there to ease your mind.

 

All brands have issues, but if you spend more time worrying about what could happen, than getting smiles per miles, time to move on.

Ecclesiastes 11:4 says, "Farmers who wait for perfect weather never plant. If they watch every cloud, they never harvest". (NLT)

 

A failure can happen in the first mile or the millionth. Waiting for it with anxiety will give you an ulcer. You drive it every day. You have a 'feeling' about it trustworthiness don't you? Is it giving your reasons to doubt it?

Hey guys, I know I’m late. I’m from the T1 forum. Just a heads up, my 2020 trail boss (4.3/6L80) has blown through two converters in 50,000 miles. First one went at 25,000. They never fixed the issues and the 4.3 converters are just as shabby as the V8 converters. My question is….could I put a 300 mm billet JMBX multi-plate from Circle D Specialties behind my 4.3? The truck is 5,019 pounds empty, and they recommended a 300mm. I think they all use the same flex plate.

They are not the same converter. Not even the same style. First 4.3 converter failure I've heard of. Phone Circle D on that one. I haven't a clue. :dunno:

Brian from Circle D recommended a 300mm JMBX.

Funny, I spoke too soon. Brian said my

converter is an oddball (258mm) and he said they didn’t offer one for me after corresponding that a 300mm looked nothing like mine. I’ve gone through 2 in 50,000 miles. It’s on number 3 as of today.

      Gas Prices

      Not a distraction. You miss the point of the article. It's not just for today's situation. Another way AI is being used and it may explain some of the prices changes when there is no apparent event to cause a 25 cent jump out of nowhere, only to immediately, the next day, begin to drop by 2 cents and so on. These situations were happening before the Iran thing fired off. I thought it was interesting

      Disable AFM for $0: The M5 Method for 6-Speed Trucks

      By BlueV8 · Posted

      Disclosure: BlueV8 is a Supporting Vendor and sells plug-in AFM/DFM disablers.   Before you spend a dime with us — or with anyone — try the AFM disabler GM already built into your truck. It's the shifter, and it's free. ⏱ The 10-second version 🚫 Skip the M5 method if: Most of your miles are highway — M5 locks out 6th gear, so you cruise at higher RPM and burn more fuel You already know you'll forget — it only works if you do it every single drive Your lifters are already ticking — nothing that switches AFM off repairs existing damage You already run a tune or disabler — this would be doing the same job twice ✅ Worth trying if: You want AFM off today, for exactly $0 You want to test-drive V8-only life before buying anything Your driving is mostly town and short trips, where 6th gear barely matters Your truck is leased or under warranty and you won't touch the ECM — this is zero hardware, zero software 💡 The whole trick, in one paragraph Owners across GM forums keep reporting the same pattern: put the transmission in manual / range-select mode, pick M5 or lower, and AFM never activates — the truck stays in V8 the whole drive. Bump it up to M6 and V4 mode comes right back. Two of the cleaner threads on it are here and here. GM has never documented this behavior, so file it under "strong owner consensus," not gospel. The good news: it takes exactly one drive to verify on your own truck. Steps below. What "free" actually costs Effort, every drive. It's a routine, not a setting. Shift to M, tap up to 5, every time you get in. There is no set-and-forget here. 6th gear. When GM shipped trucks with AFM/DFM switched off during the 2021 chip shortage, its own estimate of the penalty was about 1 MPG — and those trucks kept every gear. In M5 you're also giving up overdrive, so expect the highway hit to be bigger than that. Patience. One Tahoe owner ran the L5 routine for two months, then got tired of it and bought a plug-in disabler — he had an extended warranty, so flashing a tune was off the table. That's not a knock on the method. That's just what month two feels like.   I put together the full instructions, limitations, and links to the original owner discussions here: https://www.bluev8.com/blogs/news/how-to-disable-afm-for-free-the-m5-method

      Half of you don't need an AFM disabler. Take 30 seconds to find out which half you're in

      By BlueV8 · Posted

      Disclosure: BlueV8 is a Supporting Vendor and we sell AFM/DFM disablers. We wrote this because not every GM owner actually needs one. In some cases, regular maintenance, towing use, an existing tune, or simply using M5 makes another device unnecessary.   ⏱ The 10-second version 🚫 Skip it if… You keep the oil full and change it every ~5,000 miles. Your risk is already low. You're happy shifting into M5 every drive. That disables AFM for free. Your truck tows heavy most days. AFM barely runs under load. You already run a tune or delete kit. Done is done. It's already ticking or misfiring. You need a mechanic, not a plug-in. ✅ Worth it if… You bought it used and the oil history is a mystery. Checking the dipstick is… not your hobby. (No judgment.) You're a long-term keeper with lots of easy highway miles — exactly when AFM runs most. The V4 drone and shudder drive you nuts. You're under warranty, so a tune is off the table.   The full article includes the supporting GM bulletins and owner reports: https://www.bluev8.com/blogs/news/do-you-actually-need-an-afm-disabler
