i was playing with my security system and noticed buzzing noise... thought it was my speakers-distortion...turned radio off and heard it was comming from engine...

long story short i heard BUZZING noise from transmission oil pan when ever i turned the key to ON/START position...

trans IS ACTING up lately but never had any real problems besides the jerk in on cold mornings...

any mechanics in the house????

thanks

Its your tranny pump. Your tranny fluid is low trust me. If your car is dropped you will need to fill a lil more fluid and it will go away even the jerking. Put it up and between the H and the O thats wat i do

 

I have noticed this same noise coming form my tranny pan as well. I just let it go and have never had any issues, but it made me go hmmmmm. lol It has been over 2 ro 3 years now since I noticed this noise and again have not had any issues.

I personally would not worry about it, but if it concerns you, che out what NOCturnalI30 said and see if that helps.

Good luck.
