Where to Install My Trans Oil Cooler?

[SkiprJohn]

I have a Velvet Drive and am just now getting round to installing the oil cooler for it. According to the Velvet Drive manual it indicates that it should be below the oil sump in the transmission.
How about the rest of you folks with Velvet Drive trans? Where's your cooler mounted? Perkins owners usually have one that's on their engine so you needn't reply unless you just have a comment.
All comments are appreciated.

I always install coolers above the sump level either on rear of bellhousing or on bracket over rear coupling ,always lead water thru cooler first before engine coolers ;heat is the gbox enemy.

Mines above the bell housing. A couple of years ago one of the hoses developed a pin sized leak that sprayed a fine mist of oil all over the engine room - what a mess.

Thanks folks for the reply. I'd seen them mounted there before but then that contradicts the instructions for Velvet Drive.

I just checked the instructions again and it says, "Install cooler in a position which will insure it is filled with oil at all times and will not drain back to sump." I guess this could be interpreted to mean that if I place the cooler so the inlet and outlet fittings were on top of the cooler then oil would stay in the cooler and not drain out when not in use.
Thanks for your input!
Another question: Sometimes I don't think these things through enough.
Do the lines going to and from the transmission carrying hydraulic fluid need to be high pressure hoses?
