Trans Cooler Help

Depends on where you mount it. If in front of the radiator isn't an option, then having one with a fan is a good idea for the tougher cooling jobs.

As was mentioned, a trans fluid temp gauge in the pan is a very good idea. My own limit is 220°F Past that and I stop doing what ever it is that I'm doing and let it cool down. I've been told that the OD versions of the 727 trans don't circulate fluid when in Park, but do circulate it when in Neutral. I would assume that this is also true of non OD 727's.

Metal tubing is better than hose for this use because it too acts as a cooler. The longer it can be, the more cooling just the plumbing can do for you. I would still convert to hose to make the jump off the chassis to the engine/trans. I know that none of the OE's do it and I've long thought that a poor decision made by economics.
