Im sorry guys i left out a bunch of info
Transmission 4L65E…Flush 80,000
Hi guys my Nali is in excellent shape for its age and I am really in love with it…but…I come from a family that usually runs foreign cars that usually go to 300,000 miles without a major problem. My main question today is SHOULD I KEEP THIS DENALI??? The issues I have had so far include 1 water pump and a radiator at around 80,000 miles. Also at that time since transmission cooling line in the radiator busted and coolant was getting into the tranny they had to do a full flush. I am now receiving my truck from my mechanic after another radiator replacement and leaky oil pan gasket. This time I requested the AC Delco radiator vs the aftermarket one they used last time in hopes of getting more life out of it. Last time they replaced the radiator they flushed the system and replaced it with dex cool, this time I had them use the normal yellow stuff.
Even tho the system got flushed will the yellow stuff hurt any components in the system that may be used to the dex cool?
Is it normal for aftermarket radiators to not last as long?
For all the people with the third rows do y’all have as many rattles in the cabin as I have? Is there a way to correct them to make the ride seem more solid?
Its almost time to replace suspension, is it worth it to swap my auto leveling suspension with standard struts? Is there a ride difference? (I know there is a price difference)
Provided I repair EVERYTHING on my truck at FIRST SIGN of WEAR like I do, how long will this transmission last? I hear such bad news about these transmissions. And if it get it replaced is it hard to stick in the 5 speed instead?
I’m forgetting like half the questions I want to ask but they must not be all that important to me so forget it…
Thanks in advance
