2020 5.3 V8, 8 speed. Will the transmission actually last?

Huh? What is a serious issue? A failed sensor?

30 years ago the SES could be illuminated indefinitely with little consequence. These days a vehicle will shut itself down and you'll be calling a flatbed all in the name of "emission controls".

One mustn't dirty the Kings air.

That boat sailed about 30 years ago. If you can get 5 years out of a late model vehicle with out taking a serious beating you've beaten the odds.

 

Let's see....Pepper is 6 years + and a stones throw from 150K, a legal lifetime, and I've replaced: 

 

1.) An $8 pinion seal most would have never noticed 

 

2.) A $12 plastic starter shield making noise.

3.) Corrected a faulty factory wheel alignment. (All over the map "in spec".)  

 

Everything else has been normal maintenance or damage repair. Ya know, like the dog chewing the shifter stalk. Rock chips etc. Or one of my many project obsessions. Consumables. Oil, gas, 2 sets of wipers and 1 set of tires. Filters. Normal stuff.

 You would be hard pressed to have a reliable high mileage vehicle 30+ years ago that you would trust and easily last hundreds of thousands of miles without plenty of TLC.

I have no idea how old you are Tyler but this is NOT my experience. I've never had trouble getting 250K out of anything I put a key in with normal care. I've been driving 50 years. Okay, more than 50 years. 

 

If you had trouble getting those numbers then you drove so little it rusted away before it wore out. 

 

Ya know what didn't break on the old stuff? The INFOTAINMENT center. The computer. The ABS. The TCM. BCM and there wasn't much you couldn't fix with a screw driver, fingernail file and a matchbook to get you to the next town.

Back to the OP’s question... I remember reading on the Camaro forum a couple of years ago, after the 10sp starting going into the SS’s and higher trims, that the 8sp, despite its quirks and nuances, is a stronger transmission (capable of handling more power stock).  
 

My Camaro still has the harsh 1-2 shift first thing in the morning, but, after about 3 fluid changes, that’s my sole remaining complaint.  I have about 9 months of powertrain warranty left on it, and I’m close to adding more power (about 485HP today and shooting for 550ish) and will only tune the trans, no other trans mods, with no worries about it holding up!

Hey everyone,

 

Thank you all for your responses! I think a little encouragement was what I needed. I absolutely love this truck and can deal with a couple of harsh shifts. I was just worried about long term damage as a result.

 

Thanks again!

Huh? What is a serious issue? A failed sensor? A frozen touch screen? A memory seat recall not working? Vehicles these days that statement is quite the opposite. You would be hard pressed to have a reliable high mileage vehicle 30+ years ago that you would trust and easily last hundreds of thousands of miles without plenty of TLC. Lets put it this way, I would take a 5 year old 100k truck from today and drive it around the country, I would be more leery of taking a 100k mile 1985 truck around the country. If something were to happen it would be easier to fix the older one but the chances are higher the new one would be trouble free. They may have been simpler but no way more reliable than todays vehicles. Now the meat and potatoes of vehicles are much more stout and better lasting than yesteryears they do have a ton more sensors and technologies that can fail and cause an inconvenience but it is very rare to see a major mechanical failure today outside of the roque manufacturing defects or supplier issue (not to say it doesn't happen but it is rare). It is much easier to keep an older vehicle running with it being simpler and if you are mechanically skilled to work on those failures but again, more reliable that is a hard no. 

 

OP, to answer your question, YES. What you read on forums is a very small percentage of people and it is more geared towards complainers, that transmission should give you a long time of trouble free running.

LOL, I always knew there would be people like you who would buy my craptastic Ford EcoTurd with just over 100K miles on it. The older trucks were more reliable because they were simpler and didn't have things like turbo-charged engines to save miniscule amounts of gas or electronics prone to fail that take out your entire engine. That being said, I'm hoping my electronics-laden 5.3 DFM Silverado lasts longer than my turbo F150 did, but I'm not hopeful...
