Hello all. I have a 2011 LT. It has about 150,000 miles on it, 75,000 of which are mine. The car has some transmission problems, overheats going up a steep hill, and intermittently has the gauges bobbing up and down. Realistically, am I going to get much more mileage out of it if I put money into fixing it?

Most get more than 300,000 miles, if the owner cares enough to do regular maintenance.

You have a lot more to go with a bit of work here and there.

The gauges are most likely because the fuse box bolts need to be tightened. If the bolts feel "tight enough" give them some more.

I just crossed 210,000 and still going strong.

I’m at 186,000 miles on my 2011, I put 400,000 on my 2007. So you’ll be wise to change the Dexcool, install a new AC Delco 131-158 thermostat, and change out the timing chain and balance shaft chain and water pump. A small investment for another 150,000 miles. Your transmission problems could be related to those fuse box bolts
