Old, but a good thread. Nice pictures and installation.

After reading it I'll revive a subject often not touched upon, the operating temperature...

I noted this information from B&M in the link from post #4:

"Monitor the transmission fluid as the fluid leaves the cooler and returns to the transmission. Monitoring the returning fluid will give you an accurate indication of how efficient your cooling system is functioning.
A good operating temperature of an automatic transmission is 160º to 200º F as the fluid exits the cooler."

And also noted from B&M was the optional use of a cast deep oil pan for the transmission that can increase capacity allowing more cooling ability.

And then from this source, they state 150 degrees is considered the 'minimum' ideal operating temperature.

Rhetorical questions and something to consider...

How many actually install a transmission oil temperature gauge and monitor it ? Can you use a trans oil cooler that is too big ?

I've used a larger size Earl's stacked plate cooler before (company link below) and considered it a bit large for my application, but also noting I ran an aftermarket deep pan with the extra capacity.
Often the transmission oil temp only ran a tad over 100 degrees when cruising around on the open road. The temp sending unit was located in the pan on the transmission.
