Coolant issue

Has anyone checked the EGR cooler yet? Very common failure point.

 

Has anyone checked trans fluid? Does it have a water cooled trans cooler?

Seen a isx rebuilt twice for this problem.

Now I'm stretching and can't recall model. But wasn't it a eaton trans that had the aluminum case with coolant passages internal, only used a few years and abandoned for being garbage. Its been 10 years since I was looking for a back section for one. Dont remember the model.

 

Believe it was the "lightening series", predecessor to the FRO's, but memory is foggy too!

 

Was it the lightning? It was a aluminum case that was not used long. But coolant passages and when it was worn the bearing cups wore into housing. I spent three weeks locating a good back half cover. Tried to get them to put a FRO in. Company wouldn't do it.

 

FRO was older and not even close to the same design. While I do not like the Metric, FRO. Its twice the trans as the turd I'm thinking off.

 

Probably what’s wrong, probably didn’t need a head. Why didn’t they replace the head when rebuilding? Must have tested good. Unless the mechanics guessing like we are. Lol.

 

inside mechanic, throwing parts at it. who rebuilds a engine and puts a head on 60,000 miles later.

 

I would check the egr cooler. Very common issue.

 

This is the "Lightening" top two.
