tranny cooler take home? he didn't get the car to the track so can't comment on whether his setup works or is needed, but apparently not needed for street use. i would assume it would provide some benefit at the track. from what i can see the cayman and 986 5-speeds are the same. personally, i'd replace the temp sender with a check valve to keep oil from backflowing into the tranny when the pump wasn't running; just hearing the fan run (or not) is a good rudimentary temp indicator.
oil cooler?didn't work, apparently. looks like the oem oil cooler delete plate from ln engineering might be a bad idea (heaven help me for saying that). makes more sense to me to keep the oem cooler and supplement oil cooling with a canton sandwich plate feeding an additional cooler. if you are keen on the ln engineering piece, he's selling his for cheap in the planet 9 classifieds.
