I tried the Fred Scoop, but with the lack of air flow in traffic, it didn't do much good. The 2x+ sized cooler did the job. As a matter of fact, I just recieved the AN-12 to Jiffy Tite connectors last night. They made me up some from scratch since they are not a part.
This will allow me to mount the new cooler in the same orientation as the OEM without any hoses.
I was really impressed with Jiffy Tite and their support for a guy trying to mod his truck for better cooling. They were even going to pass on my info to GM. I do need to get back with them as the fitting threads are about 1/8" to long for a good seal, but I can trim them down. Like I said, they are a class act IMHO.
Remember the old saying, there is more than one way to cool a tranny.
