So my 46re in my 98 ZJ 5.9 limited has 220k miles almost.. shifts exactly the sane as the day i bought it 11 years ago. But now its whining. Really loud too you cab hear it with the window down and people can hear far away. Its a whining whurrrrrrrrrrrrrr nkise.. gets faster as i get faster.. isnt there at a stop. Only happens in 1st 2nd 3rd.. but in overdrive or lockup. Its gone. If it down shift back to 3rd.. its back. Upshift to overdrive. Gone
What could cause all foward gesrs to whine but not in OD ?
