I just read about this not to long ago on another forum.Yes, never heard anyone else complain or talk about that same issue of mixing in radiator.
I had this happen in a Chevy S10 I owned in high school. The GM Dexcool would rust out the radiator between the radiator and trans cooler. Destroyed my transmission.I just read about this not to long ago on another forum.
Of course it could be the same guy posting there too. LOL.
There is a finned aluminium looking cooler in there.
Somebody showed a picture once. Resembled this:
Said it leaked somehow and it was all down hill from there.
I've had this radiator, CSF 3 core, for about 12 years plus. This is the first I had ever heard of it as well.
Apparantly it's not that uncommon, from what I'm hearing from others once I tell them what happened. One guy said that's why he bypasses the radiator all together and just uses a separate tranny oil cooler.
So far the fluid color is getting more red(redder?). I'm just on my 6th gallon and this is getting expensive to be buying all this tranny fluid.
On a side note, Walmart has the fluid for way cheaper than O'reily's...$13 vs $20+
On another weird note, the Walmart brand of tranny fluid is $3 more than the Valvoline brand...
what's funny is that I had just bought an external tranny cooler...however I had thought I would just run it in series with the radiator cooler as well...I just got my XJ back together, I disconnected the trans cooling lines from radiator and bought a simple external cooler (~$50). Never had the issue, but this is cheap insurance!

I'm slowly headed that direction. Almost rolled it over the front last time I was out. Already bought harnesses. Will prolly do a harness bar to start with just to get them in while I'm deciding on cage designs. These days there are a couple pre bent options for hybrids.Not unless I decide its time for a cage. Which unless I start getting out more often I don't see happening.
