03 Flair V10 Trans Cooler

[ryano2121]

My 2003 Fleetwood Flair 33R with the V10 has a transmission that is getting too hot. I had a shop go through it after it boiled over and it's fine but I don't want this to happen again of course.

I'm thinking I want to add another transmission cooler. Does anyone happen to know what size the fittings are on the stock cooler? And which line is the return?

While adding a secondary cooler never hurts, I would be concerned that the reason for the overheating is unknown. It doesn't just happen.

The stock cooling system will be the radiator, with the tranny fluid lines routed through it, probably at the bottom.
