1999 f250 tranny noise

Greetings all, I'm checking out a 1999 f250 crew 7.3/auto.Low mileage clean truck,my only issue is a strange muffled grinding sound coming from trans area maybe around the torque converter.Noticed it idling in park.Could this be a performance torque converter?Should it be audible?Any help would be much appreciated.

I'm no expert at all, but if I recall correctly the '99s were notorious for this noise. A lot of folks say it sounds like marbles in a coffee can?
I haven't heard of any exploding first hand, but hopefully someone will come along with the info. Stock torque converters aren't too expensive, and you could put in a shift kid/ built valve body in while the trans is out if the rest is solid.

hope this helps a bit, at least a

I know two people with 99's and theirs made that sound for a few thousand miles then the converter went out. If the price is right it wouldnt bother me I would just figure on replacing the converter right away before it comes apart and yes it would be a grea time to upgrade valve body and converter.

Hey guys,
I am new to this forum and actually to the world of powerstrokes. I have a 99 f250 as well, only had it for a week and a half now. It started making a weird trans noise in park and neutral only. It will make the noise for a few seconds, then stop, then go again, in a very erratic pattern even with RPM's at idle staying the same. I listened to a few youtube videos of bad TC and it's not the same noise. Just curious for your guys' insight.
Thanks

if the noise goes away with light throttle, in neutral, its the flywheel. Its cracked around the bolts.

Should I be able to see that by just taking the inspection plate off?
