Hello
Can someone help me find out what my Th 400 comes from.?
On the small tag on the trans itīs some numbers: F300D and the serial number is 85 FD 3318. And on the tail shaft its a casting number: 8624486. The converter is big and with 6 mounting holes.

Thanks
John

it looks like it might have come out of a 1985 diesel series c, p truck
