Hello all!
Back in February, I traded in my 2016 Nissan Altima w/ 83K miles for a 2014 Lexus ES 350 with about 124K miles. I bought the Nissan before discovering what absolute junk they were and before discovering Scotty’s channel. A week after I purchased it, I had to replace the CVT transmission. Thankfully, it was covered under warranty, but it blew my mind that I would need to put a new tranny in a 3 y/o (at the time) vehicle with only 75K miles! I drove it for about a year and a half afterwards before scoring an insane deal on a 2014 Lexus ES 350 that although was older and had more miles, has proven to be a very reliable vehicle as I have seen numerous of them with well over 200K and 300K miles on the clock.
Since buying the vehicle, I have replaced the serpentine belt, spark plugs, brake fluid, coolant, tires, front brakes, cabin filter, changed the oil, and some other custom cosmetic “mods” (LED interior lighting swap, aftermarket exterior rear-view mirror turn signal swap, etc) all on my own since I’m a Lexus technician. Pretty much the only thing I haven’t touched on this car is the transmission fluid.
The vehicle starts every time with no issues; runs, shifts, and drives perfectly. The transmission shifts EXTREMELY smoothly and doesn’t slip or jerk. I just passed 132K miles a few days ago. What I’m wondering is if it would be a good idea to drain and fill the transmission fluid at this point, or if it’s too late and I shouldn’t touch the fluid. I know that performing a “flush” is a BIG no-no, so I’m definitely avoiding that route. I just am not sure if draining the old fluid and putting new fluid in would be worthwhile or if it wouldn’t really be fully necessary.
Thank you to everybody in advance! I appreciate all of the insight from Scotty, the admins, and everyone else with much more experience than me!
If it were my vehicle and I didn't know when it was done last, I would change out ALL the fluids and appropriate filters in the engine, transmission, differential(s) and grease all lubricatable zerk fittings. The I will know the status of the vehicle instead of guessing.
