Tranny Noise
01 F250 PS w/110,000 on the clock.
When the truck is cold everything is fine. However, after everything warms up I start to get a whine from the tranny. An example of when this happens is, go down the hiway everything is OK (going aroujnd 75MPH). Take the off ramp get on the frontage road to go home (now going around 60-65) I get a whine from the tranny. The RPMS are OK for the speed (right around 1600-1700) so I know I'm in fourth. I can turn off the O/D the RPMs go into the hi 2000's, let it ride this way for a few seconds then turn on the OD. Sometimes the whine goes away, other times I have to do this 2 or three times then it goes away.
Torque Convertor? if not then what.
Tranny serviced at 98,000. I've checked the fluid level and it's right in the zone.
Thanks for all the help
