Hey guys, been a while since I've been on here. A little background on the question:
Ever since my truck sh*t the bed, my parents have been on the hunt for a vehicle. I believe at this point I am going to end up with a 2006 1500 suburban. A little background on this particular vehicle, because it's a bit of a unicorn, and I have the factory build sheet to back all this up.
It has the 5.3 v8, paired with the 4l80e tranny, with the heavy duty tow package and a separate trans cooler. It's 4wd, with 4.10 gears, and locking front and rear diffs. Hydroboost brakes. It's basically a 2500 drivetrain, packed in a half ton body. As it sits now, it has 230k miles. The engine has had regular maintenance. However, the transmission has never been serviced, and that is starting to show.
So, the delimma:
Is there any worth to swapping the 5.3 for a fresher 6.0, or just freshen and beef up the 5.3? The transmission is not a concern at the moment, as it will probably get rebuilt. Structurally, the vehicle is sound, with only minimal rust starting on the quarters, per usual with the suburbans.
All thoughts appreciated
