Truck shopping...

So far so good. He says it actually feels more powerful on the low end than the 5.3.

I have a 2023 Colorado Trail Boss with the 2.7L and I have no complaints other than the fuel economy. It's no better than the 5.3L in that regard. Plenty of power though.

Been reading a lot about the 99-06 being the best 5.3 motors...and that the newer motors have issues because of AFM..?? Our 03 Tahoe went 365k miles...never an issue.

Interested to hear some thoughts on the subject. I don't mind an older truck, and I know the transmissions are the weak link.

Educate me and then I'll post the 'truck wanted ad'...

Here is a 1-owner garage kept 1986 Suburban w/89,696 org miles, 5.7, it is located in Hershey, PA, a friend of mine is going to put it up for sale soon.

The newer GM small cube turbo engines are pretty trick, my takeway is they have reduced the number of parts. In this video he goes over a cutaway engine, describing features like priority oiling to the turbo, and lots of other cool stuff.

So now the belt replacement is now at 200k?

When are the lifters guaranteed to fail? I have 4 and need to know when to plan for this.

On my 2015 GMC Sierra 5.3 the lifter- camshaft failure happened at 110K miles. A 3K dollar repair bill. 👎👎👎! I’m not waiting for the transmission failure, going to sell soon.

How many times have you changed the fluid in the trans ? I bought my 2011 with 51k and immediately dropped the pan and installed a drain plug. I then dropped and swapped 4 quarts at a time, every 100 miles, until I had run 12 quarts out. Fluid looks like new. I now drop 4 quarts every 3rd oil change (about 20k) and have never had an issue, and I've pulled my car and camper trailers over 20k of the 84k I've driven it. Mine is a 6 speed, is the 2015 the 8 speed ?
