Removeable Trans Fluid Cooler

I'm building a T-bucket style race car with a serious racing 489 cubic inch near 14:1 compression turbo BBC engine, that will run on E85.
with a modified th400 transmission, and a 5500 rpm stall converter.
I want to keep the transmission, fluid heat levels reasonable,
and because the cars engine is only likely to be running for 5-8 minutes at a time,
during the drag racing and staging process..as we generally don,t let it idle very long in staging lines,
I don't want to deal with the weight penalty of including an added larger and more efficient, transmission fluid cooler in the car.
the radiator we have in the car is really not set up to handle the transmission fluid heat levels for a much longer time,
I'd vastly prefer to have a small cart with a transmission fluid cooler
, that I could quickly connect to the cars transmission in the pits,
to remove transmission heat between runs, any ideas?


pictures would be nice?

something like this cooler linked above, and use of a fluid cooler with quick connect fluid lines, so it could temporarily be inserted in the upper fluid line that normally goes to the upper radiator and a set of battery cable connectors of at least 10 ga with quick connect clamps for the fan motor, would work
yeah theres cheaper options but a quick cool-down requires a fairly large surface area and a fan to move enough airflow that rapidly disperses heat,
Id certainly suggest a cooler rated at at least 24,000 lbs for a fast fluid cool rate
your local hydraulic hose supply can get you two sets of quick line connectors designed for high heat, high flow rates and pressure.
one set for the removable trans fluid cooler hoses and a matched set for the cars trans fluid lines, thus the fan could run and yes you'll need a fluid pump designed to pump for trans
fluid circulation mounted next to the cooler in the cart.

I recently had a friend ask if adding a trans fluid cooler like this might be a good idea?

$571 seems rather over priced

while the heat sink style pictured above, $182 seems far more reasonable
certainly may help, reduce trans fluid or oil temps,

it has far less ability to rapidly and constantly transfer excess heat out of the fluid ,to the outside air flow,
than something like the fan equipped radiator style fluid coolers linked below
