Brown liquid under coolant cap, along with sludge build up

[J_D 2.0]

Radiator swap was sufficient. No coolant entered transmission.

The transmission fluid would be under a higher pressure than the coolant so as long as you catch it quick enough the transmission can be saved.

This is true . I neglected to mention that I cooked my transmission while pinpointing issue. So one transmission, one valley gasket and one radiator later....ALL GOOD.!

Yeah what you said about it being the radiator ended up being the case. I pulled the old radiator out which looked fine but after using a new radiator the issue has gone away. Only a tiny bit of residual crap floated back which I cleaned out cause I didn't do a full coolant flush. So far it seems like the transmission is okay so hopefully I caught it early enough. Just lucky that I'm a bit paranoid and check the fluids whenever I fill up for petrol.

LIM Gaskets, Every time,

The Radiator is only clean because its new,
But Wait, there is more,
Check in a couple of days, it will look like nothing has been changed !

Maybe after 3 months, it will look a bit better.

To get all the crap out, you will need to flush it numerous times.

You check ALL fluids everytime you fill up ?? Wow. I'd safely say your trans is fine. You'd know by now.
Not interested in anyone's thoughts, but I flushed my system by removing thermostat and adding a bit of dish soap to water. Ran that , turned on heater etc for a bit then reversed flush blah blah etc. Oils will float to top of block, heater and any other nook or cranny. Clean as now. And so it should be !!

It was only a small amount i drained the engine oil coolant and trans fluid to check conditions of all and look for water. Done about 2000kms with new radiator and coolant looks great. Before it would of had a thick film of that yellowy paste sludge build up.
