Cooler Q's

I want to install a transmission cooler on my truck. The 700r4 is about 2 years old and is connected to the factory cooler. I have metal lines going from the transmission to the radiator.

Can I totally bypass the factory cooler and use a bigger after market cooler?

What about the factory metal lines? Do I have to get rid of those entirely? The kits I have seen do not come with fittings into the transmission.

Will having the new cooler in front of the AC and radiator hurt the cooling and performance of those units? I do have a pusher fan but it barely fits behind the grill. The fan is on the drivers side. I wanted to put the cooler on the passenger side.

Any help including links to stuff you have used would help out a lot.

You would do better to run both. Run thru the radiator and then to the cooler and back to the trans.
I got nuthin....

I used to run a big tranny cooler separate from the radiator, I have found that you can drop engine temps several degrees when bypassing the radiator.
I used my factory hardlines and just cut them up near the radiator and used aproporiate rubber oil lines and clamps to plumb into the cooler.
I would also recommend using the factory hardlines too, as they won't get snagged and rub and wear through.
There is no reason either that your performance or cooling should be affected by running a set-up like this.
