Strange rattle

[gparrow]

Hi ya'll I got a currious rattle coming from either my tranny or rear end, it only does it when the truck sits for a while and i put it in reverse ie backing out of my drivewy first thing in the morning, it will rattle a couple times and then stop and won't do it again untill the truck sits. It's been doing it for the last couple years and does not affect performance at all, there is no slip or vibration in the tranny so i'm just currious if anyone has had this happen or might know what it is?

Thanks
Greg

Dual clutch converter. Replace it now before it destroies the tranny.

Dual clutch converter. replace it before it destroys the thans.

So it's the torque converter? If so then I'm realy disapointed as it will be the second one in the last 80,000 miles, thats crazy especially since I dont do anything with it but pull a little 4,000lb utility trailer.

Did you replace it with a billett tc or factory???

[gparrow]

Ford did it so I'm sure its a OEM replacement and if I recall it was a real pain because they had it for a couple weeks but I may be thinking of the rear main seal which is leaking again to but I cant recall which one they had it for longer

Most rear main seal leaks are not rear main seal leaks. There are several places on top of the eng that oil leaks and run off the back of the eng. You can even have a fuel leak on top of the eng and it turns black as it comes across the eng and drips at the back where the rear seal is.
