Not greg b 1,070 Posted January 17 Share Posted January 17 We run our own trucks for work. The gm as of lately shit transmission in about 2 years of use. Including mine. A lot of my co workers went to rams. They have held up better than the chevys. They go through brakes and tires a lot faster vs the chevys Quote Link to post Share on other sites

My ‘16 gasser that I had for 6.5 years plowed snow, pulled sled trailers and my Jayco Eagle 321 fifth wheel all summer through the Northeast. Never had an issue. 1 Quote Link to post Share on other sites

My 2018 I put 180,000 miles on it in 3 years. I shit a tranny just over 100k. My dad’s 17 failed about the same. It’s seems like the ones built in the last 5 years have more trans problems than the older ones Quote Link to post Share on other sites

My brother in law has a ‘17 Sierra 6.0 2500 that is literally a grocery getter for them (he’s in construction and has plenty of trucks). Lost the torque converter in less than 40k miles.

Lost the torque converter in less than 40k miles. 6 speeds are famous for the converter clutch burning up, and the debris destroys the rest of the tranny. The programming tries to lock up the converter at low speeds and in every gear, and allows for a lot of slip. Good tranny guys re-flash to eliminate it when doing a rebuild. Still having lots of issues with DOD/AFM lifters failing and taking out the camshaft too. My truck has 70k on it, 5.3 and 6 spd. I'm actually considering changing the converter to a triple disk, cam and lifters as preventative maintenance, and driving it till it rusts away.

That’s one of the first things I noticed with my new’23 gasser 6.0. The torque converter locks right up in second gear when just running around empty. My ‘16 never did that.

I noticed a slight vibration the day before at low speeds. Out of no where it lost most of the gears. Never had any engine issues other than the water pump shitting out about 170,000. The afm was annoying once it got a lot of miles on it because you could hear it activate and deactivate. I am not sure if the valves or muffler wore out over time.

ICG 126 Posted January 18 Share Posted January 18 This started about hitch weight..campers used to have weight distribution arms that leveled or lessened a heavy tongue weight. ???? Are they still in production? I opted for a simpler solution.... Doubled the springs on my dually... Quote Link to post Share on other sites
Crnr2Crnr 4,575 Posted January 18 Author Share Posted January 18 (edited) 5.3/6.0/6.2 with AFM Turn off the afm with a tuner (I prefer Superchips), when it cycles between 4cyl/8cyl mode the torque converter lockup issues begin and end. AFM in principle wasn't a terrible idea but in execution with the lifter failures they've had it's been a disaster for some. The electronic delete (tuner) is much more simple and affordable than mechanically deleting and programming them. Tuner also gives the advantage of holding a gear longer and less busyness in the trans gear hunting regularly. Edited January 18 by Crnr2Crnr Quote Link to post Share on other sites
Palu49 266 Posted January 18 Share Posted January 18 You guys gotta get yourselves a 4.8/4l60e. 35k oil change intervals with the cheapest fram conventional you can find and never even look at the trans dipstick. 9000lbs on a well balanced boat trailer and in 4wd you could even move it around the driveway 1 Quote Link to post Share on other sites

I got my Tahoe from a fire department auction for $1000 and put 100k on it. Sold it in the spring right at 200. Bought an LBZ duramax from texas and that truck was the biggest pile of shit vehicle I’ve ever owned I pretty much gave it away when the headgaskets went right after I replaced the front diff and every other part that could possibly go bad, even the almighty Allison transmission sucked in that thing. Shoulda kept the Tahoe 1 Quote Link to post Share on other sites

Shoulda kept the Tahoe Main reason ive taken so long to upgrade . My Dad owns 2 Duramaxs and they have had their fair share of repair bills as well. Awesome when they are right , but they can be money pits no doubt. Quote Link to post Share on other sites
Gym Ramstud 148 Posted January 19 Share Posted January 19 Gym transports his 9R in the bed of a Ram truck. Gym backs off his Ram on his 9R and sprays roost upon any nearby vehicles. Gym finds trailers unnecessary. Gym sometimes wants to swerve at oncoming headlights pointed too high in the air. 2 Quote Link to post Share on other sites

They probably drove in 4 wheel drive all the time “because I am Texas and my truck has diesel 4 wheel drive” 1 Quote Link to post Share on other sites
