Transmission question?

I have a 2006 crew cab with 43,000 miles on it. It has developed a whine from torque converter lock up until 2 gear shift. Any suggestions, it is full of fluid and it is pink.

Change the transmission filter & The pump to filter seal. You chould have a small leak between the filter & the filter to pump seal. The low first gear of a 4l60E will amplify the noise from the pump sucking air.

Is the filter inside the pan like the 400's or the 350's? Thanks for the info.
