So there's been a fair bit of chatter in recent years of people installing a deeper pan on their transmission, but it seems most insist it must be accompanied by a means to lower the filter closer to the bottom, lengthen the dipstick and maybe a mod or two more. Is this absolutely necessary, and if so, why? I realize the unit will not be able to access the extra volume so it would be just extra volume, but since the dipstick is calibrated for the original filter configuration if you just fill to the dipstick wouldn't there be adequate fluid for the pump, or am I missing something here?
Now the reason for the question - I inherited a new 727 pan that was made at least 20 years ago or so that's intended to add extra cooling by having several finned tubes running through the bottom of the pan, (and even has "turbulators" installed in the tubes). These tubes are open to the atmosphere and air flow to add the cooling. These extra tubes would obviously interfere with trying to lower the filter to nearer the bottom of the pan. I realize this won't be near as efficient as an external front mounted cooler, but the pan is new and not beat to crap, so why not use it?
