I forewarned you that transmission needed special Toyota equipment in order to safely change the transmission fluid and that it isn't a backyard mechanic job. I even posted the Technical Service Bulletin about this for you. I shared this information for your publicly and also sent you a private message to be certain you received this critical information, as another member here was providing you incorrect and bad advice about this.
Toyota Transmission Fill System (43k PDF) (Revision: 1/12/10)
For some reason, you didn't heed my advice and proceeded anyway.
Now there is a problem with the car. :blink:
I tried.
I hope the very expensive automatic transmission has not been damaged.
A member of the Corolla Forum who has no professional automotive training, is not and has not been employed in the automotive industry, (as I have been for many years), encouraged you not to take my advice,
not to use the superior performing, less costly to use AMSOIL synthetic ATF and
not to change the transmission fluid using the recommended Toyota special equipment. Will that person now pay for any damage that has been done to the transmission? :unsure:
Which automatic transmission fluid was used?
Why didn't you listen to my advice? Did you think I was lying for some reason?
Yes, it would be prudent to get the vehicle to a competent Toyota automotive technician in order to evaluate what has happened to the car. Whistling noises are not normal of course. I'd call the Service Department of a Toyota dealership and inform them of the situation and ask them if they recommend not driving the car and have it towed to them instead so as to avoid potential further damage.
I sure hope the automatic transmission has not been damaged.
For the benefit of everyone in the forum here, keep us posted.
Good luck with it.
