I have a 4l80e with a 3600 stall now, it was previously a 6 speed car. I have the large b&m cooler and frame rail one can I run one into the other or should I y it into both. I hear both ways I don't want to much pressure and tear things up.

Run the large B&M cooler by itself out front on the radiator and monitor the trans temp. It should be sufficient to cool the 4L80e. More than one cooler can become a restriction and cause the trans to run hotter.

Also remember that if you are using a cooler with the ports facing sideways you need to run your pressure line to the lower port , your return line to the top port. if you are using a cooler that has the ports facing up, turn it so the ports face down, when they are facing down it does not matter which side you use for pressure or return. you have to plumb the coolers up this way or you will not get flow through them.
