Make sure the lower cooler line is the feed. If you run it thru the cooler top down it may not cool correctly.Do you have acsee to an infared heat gun? You could use it to check the temps.

Really? Doesn't the pump push fluid through the cooler at same rate regardless of line orientation?

If your running road gears 2.76 3.23,with a 3200 stall might give you a problem.I think it will overheat the fluid in the converter,because the stall is to high for the gear ratio.Example 55 mph 2200 rpm,3200 stall.Your stall speed should be below your crusing rpm.

Well something in the story is missing. You said the tranny was leaking bad after cruising. If you read my reply then you know the valve body causes this problem (somehow). Now you say that it sounds like it is severely broken, that doesn't happen from overheating. Did you romp on it in first and let off hit it again, if your valve body doesn't have low band apply then that is what probably broke the internals and be happy that it didn't come apart entirely :-(

Call me if you need help pulling it John. I've got the 5A all tore apart right now in the middle of a 518 swap.

I had a torque converter with a crack in the hub where it goes into the pump and it leaked pretty bad, but that was a 904 transmission?
I like the vent relocation to the rear of the transmission too.
