Thread: Why is my automatic transmission whining?

I just had it serviced, not flushed. It had the pan dropped and the fluid and filter replaced. It is a 98 pontiac bonneville se with the normally aspirated 3.8. The transmissiion was perfect and completely silent before the fluid change it was just way overdue mileage wise for service. Now it makes this noise all the time its pitch changes with engine speed. I have heard cars (not mine) making this noise and always wondered what caused it?

I don't have the money for a new transmission or car.

What is causing this and what should I do?

re-check the fluid level in it when those get low on fluid they wil do that ,they may not have gotten it full enough on fluid and that will cause that too happen,if it is fill it back up or it will damage it and get in touch with who ever done the work their responsible for seeing that the job was done right on it,good luck.

maybe something is stuck in the transmission!

check to see if it needs more transmission fluid.
