Has anybody used an automatic radiator in a manual car?

Did you see the pictures? The e53 uses an external heat exchanger. There is about a 1/2" hole that will dump the coolant out as fast as you pour it in if you don't seal it up.

Again, as someone who just went thru the same thing, those plugs need to to hold coolant. IMO it was not a trivial task to plug them in a reliable way.

A plug with an o-ring in it win't be difficult to make. I should have it done this evening. Once in place, it will only have 5 1/2 # of force on it if the coolant cap regulates pressure at 2 bar.

Ah I didn’t know the ATF cooler was external. Nevermind.

Fortunately these are not Mercs with the self destroying cooling system where the combined radiator fails and leaks coolant in the auto gearbox oil before anyone knows it.

Don't overlook the infamous Nissan Strawberry Milkshake of Death!

At one time, before Nissan went wacko and started putting CVT transmissions in everything (before I retired in '15), I had considered getting an early (2002-2007) X-Terra, Pathfinder, or Frontier 4WD as a project car, until I read of all the problems the automatics had with the combined radiator/transmission cooler bleeding fluids together...the Strawberry Milkshake of Death.

The problem ceased in 2010, after Nissan corrected the problem, but my budget said no to those later models, so I didn't get one. I waited awhile, and fixed my attention on a X5, instead. Lucky me! ?? !!
