Collapsed Transmission Cooler In Rad
I got my transmission cooler back from my rad guy and had the time to cut it open at work and here is what I found.
The inner coolant passage has totally collapsed not allowing any cool coolant flow down through the centre of the cooler body. Thankfully it opened up the passage for the transmission oil flow through the outer wall passage of the cooler.
To have the inner passage close up that tight, to me this looks like it was caused by a huge pressure differential between both passages within the cooler due to my plugging of both transmission ports witt NPT fittings when I was running a manual transmission.
