1999 Suburban noise, transmission or Torque Convertor
Hi all. New to the forum. I have a whining noise that has gradually gotten worse and am trying to determine where it is coming from. Ruled out the power steering pump after removing the serpentine belt. The noise is present in DRIVE or REVERSE, not present in PARK or NEUTRAL. The pitch changes with RPM and is present in 1st, 2nd and 3rd gear. Can't hear it when cruising down the highway. I've also noticed a slight shudder once in awhile when cruising about 50-55.
The truck has about 157K miles, but had the tranny replaced at 90K. My brother was the original owner and said the torque convertor was not replaced, so this is what I'm thinking is the problem. There are no shifting problems, just the annoying whine. Any suggestions? I recorded a video but saw no where to post.
