I have a 2000 Pontiac GP SE 3.8L with 153k miles on it and it won't shift into OD. It runs at about 3100 RPM when driving at 70 MPH. There is a whinning noise coming from the front end. The whinning noise only happens when it should be in OD. No matter the speed. I've read on previous post on this forum that the 4th clutch hub might be causing this. Do I have the same problem? And is it hard to fix? Any help is much appreciatted. Thanks.
