HD TH400

[FlapDisk]

So I picked up a transmission for my buggy tonight and was told it was a th400 out of an old military truck. It has HD stamped on the housing and from what i have read there was a heavy duty version of the th400. Is this one and if so what are the differences between it and a normal th400?

This thread has some good info on different th400 castings.

i think the only difference is that it has a stronger case, thicker around the bellhousing area....nice find!
