3)What size/capacity would you suggest?
4)The one thing that concerns me is the airflow restriction that a large cooler would cause if sandwiched between the condenser and the radiator.
5)On the valve bodies, they are $350 but what can I expect for labor costs and won't I have to ship them my old valve bodies and wait to get them back? Thanks for the input.

1) All years.
2) The factory ATF cooler is a single pass hollow brass tube about 12" long.
3) It depends on alot of things.
Climate, transmission condition, driving style, driving conditions, traffic, etc.
The best way to determine the cooler size is to find out what your transmission temperature is now.
Too big and you will never get torque converter lock up,
too small anf you are only mildly better than the factory set up!
More on this later.
4) On my hottest running SVX, the one with a 7-11 PSI blower, I was running a huge cooler, maybe 15" X 11", and before the hi flow ECUTune valve body it kept my ATF to no more than 190°f on a 100°f day, while dragracing or autocrossing.
BTW, even with a huge cooler, properly mounted airflow is not a problem.
5) I will have to estimate this one...
Raise the car, drain the ATF, drop the 20 bolt pan, drop the filter, carefully drop the valve body, take the new valve body, using a trans jack, carefully reinstalling the VB, filter and pan, refill trans.
Here is a copy of my bill to change out a valve body for a recent customer.
I hope that this helps.
