Weird noise need some help!!

[jlds91389]

ok so i will try to explain this as best as i can. I noticed that when take off normal, when the car is in first gear there is this kind of whining noise. it not high pitched or anything and it only does it in first gear at? the car also just feels slower. i'm not sure if that matters or not.... could it be my tc? The car is an 01 auto and i just drained all the fluid including the converter about 2 weeks ago. it was doing the noise before the flush and stopped for a while. thanks for any help .

Go back and check your fluid level. That would be my 1st step. Also what fluid did you use?

checked the fluid level and its good... also is red like its supposed to be. and as far as fluid i used valvoline mercron5 like it calls for
