I had a 10 vane kit put in my trans, GM parts, clearanced. I'm confident
in the local guy. But the pump appears to whine at high pressure. At part
throttle I never hear it, but under heavy throttle I hear it. Also it happens in
manual second. The whine changes pitch with RPM. Its more of a whine than
a buzz, almost a whistle in pitch.
I thought it was the new converter we put in at the same time.... I changed the converter
and the whine is still there. When I could reproduce it at light throttle
in manual second I became convinced it's the pump.
Bruce, Don, Lonnie...... any ideas?
Thanks!
