Hello Scotty,
First of all, your YouTube channel is my favorite above all. Thank you very much for your infinite wisdom and down to earth explanations.
I bought 2012 Lexus GX460 about a year ago (EOY 2022) with 160,000 miles on it. The exterior looked decent except a minor paint peeled spot on driver side rear due to a “minor” accident. The engine is super smooth and It drives really well up to 60, 70 miles per hour. Plus, it goes straight and no bolding spot on any of the 3 year old tires. Judging from the Lexus owner’s website (by VIN number) showing it’s been serviced by Lexus up till 2 years go. What I am wondering is the transmission fluid. There is no mention of replacing/flushing the transmission fluid anywhere, except “level checked, serviced”. I am ready to drop the transmission pan and replace the transmission fluid; but, I have this nagging feeling after watching your video talking about “never replace transmission fluids when it was never done for high miles”.
I am sort of counting on the Toyota quality and the high miles must be due to freeway driving by previous owner(s). What do you think?
Lastly, a question on how these truck engines drive.. when I try to pass slow moving car ahead of me by flooring the gas pedal, I don’t get the extra pull (e.g. dropping the gear with high RPM) responsively. This may be due to my expectation after comparing it with a BMW 528i, my second car. Is it normal? Or can there be something I should check out for any possible issue? Perhaps, the above transmission fluid replacement may help improve the response? What do you think?
Thank you always! You are the best!! Have a wonderful day!!!
you're driving an SUV, not a little coupe. Of course it won't accelerate as quickly.

what does the fluid look like?
See our FAQ
Thank you. I will make sure to update the fluid color/condition soon.

Your transmission may be starting to slip. The whole idea of a downshift is to deliver more torque to the wheels (being pulled into your seat). There's a torque band at high RPMs. If anything, a truck should have more torque for towing, sacrificing top speed. It's too late to change your transmission fluid. If you change it, will most likely start slipping even more.
That's what I am afraid of... as Joe mentioned above, I will check the fluid color/condition and report back. Thank you very much!
