Trans cooler bursts!

[IRA51]

what about the 2 lines on the drivers side of the rad ? my rad has 4 lines 2 on each side that go into the plastic tanks on ether side of the rad .

I looked all of this over today and I would not just loop the oil cooler lines on the drivers side. There is so much room over there that you might jut as well add a small cooler, or clean out your factory tranny cooler and mount it over there.

On another note- how many of these trans coolers are bursting, and are they bursting on the 03-04? or newwer? We added a second tranny cooler and a fan on a 1500hd this weekend... the second cooler was unnecisary, but the small 8" fan rocks..... Set up on a thermostat....

The issue is not in the trans cooler itself. It is in the side resi of the rad where the lines pass through. These are located on the passengeer side of the rig. The larger tubes are located on the drivers side, which go to the engine block....thinking some kind of oil cooler. I didn't touch them.....trying to investigate if anyone had any issues with this bursting, causing oil to mix with antifreeze......that would suck! If no issues I plan on leaving it alone.

mine just did.

~14k miles

GM would not participate in any repairs, under any circumstances.

talked my way up to John Martin (regional guy for alabama and mississippi)
678.787.7200

~$2000 for a new radiator, external tranny cooler, and some other work.

pulling out the stops for a 4L80E - I'd rather blow a diff than another trans.
