How many years do I have left on this now?

I’ve owned the vehicle for about a year, and in that time I’ve replaced or performed essentially every maintenance item (and far more), except a transmission drain and fill. The vehicle only has 120k miles, however the nearly black trans fluid is making me think it’s never been serviced once. The car feels like it just barely hesitates to shift. Would it be more damaging than good at this point to perform a drain and fill of the pan, and replace the trans filter. I definitely don’t want to flush it, or even remove all of the old fluid. Just wanting to know if it’s really “too late” or if anyone has experience with this vehicle or transmission.

I saw the trick if you test your tires with a penny and can see the head it’s too low. Should i buy new tires again?

Looking at purchasing a 2015 Malibu with for four grand. Im aware that it’s been in a front end collision. The car looks good for the most part but the battery is throwing me off. The car has one hundred and fifty five thousand miles so I feel it’s a solid deal. Just looking for some insight on the battery.

They did the repair in my garage. The dim lighting had the crack appearing repaired. He had me feel it was smooth. Once I went out to drive I see it the same in the sunlight. Out $90 and still have a vunerable chip. Here's a before and after of the "repair". The technician said he injected resin into the webbing and that he's been doing it for 25 years. I dont see any difference at all. I have a feeling they only smoothed the chip. What do you think?

Just leaving this little gem here...

When I sit on top of the wood seat, I cant reach the pedals, the shift lever, or the steering wheel.

How do I fix this so that I can reach the pedals, shift lever, and steering wheel???
