I have noticed a few dealers who have advised against changing the oil and the reason is the standard reply that new fluid could cause failure. That is an old tail that applies when a transmission is old, worn out and already giving you problems. Otherwise changing the fluid is just good maintenance. I would be careful that they are qualified to do the procedure correctly. Don't be shy about talking to the mechanic that actually does the work before turning over your car to them. Any hesitation in his reply or things like "oh you don't have to do the temperature reading to refill", go find another dealership.
Thanks for replying. I’m always amazed at how helpful the SMEs are in forums like this.
I’m old school regarding car maintenance. The fine points I’ve read here as far as the meticulous process in getting the transmission oil changed make this a potentially error-prone process with potential catastrophic consequences to the consumer.
I’m not sure what to do ...
I’m thinking the following:
- Use a dealership as they would be best to absorb liability.
- Sit in the passenger seat as a dealership service rep drives the car as to prove that I’m handing off a car with a flawless transmission
They say lifetime oil, but that defies certain common factors such as evaporation. From a liability perspective, where they say lifetime fluid, if my transmission fails in the future, I don’t think I’d have a strong case against being able to “blame” them.
Ultimately, I guess my original question (reworded) stands:
For those of you who see several sealed transmission system Camrys on a daily basis...
How often do you see Camrys come through with transmission failures?
Of the ones that do come through, what subset can be rooted to not changing the fluid?
